Trust me, Jared Polin will never, ever be my Guru. That said, I have been having obviously demonic suggestions that I should get the MC-14 Teleconverter for my Olympus 100-400mm -- however, after much prayer and thought I have decided against it. Your inspired video helped to confirm that my decision is the right one. Truth is, I am one of those oddballs who shoots almost 100% Jpeg (Gasp!), and have found that my handy dandy DTC (Digital Teleconverter) function works every bit as well as cropping in post. Thus I have it programmed on my E-M1X to the Video button since I am strictly a stills photographer. If I need a tighter crop than my lens @ 400mm, I simply press the magic button and 'Wallah!', I'm at 800mm with no change in exposure speed, and that crop is to the sharpest part of the image. The only reason I have considered the 1.4X tele is due to good old fashion Greed -- I thought, if I can get 1600mm equivalent with the DTC, then the 1.4X will give me 2240mm! There is no end to the depravity.

[@CallMeRabbitzUSVI]

It's not a halving of image quality, closer to about a 30% loss in sharpness and contrast but you do get more detail since you are physically zooming into the subject and today with High resolution cameras and Upscaling tech the downsides can be easily mitigated

EPIC video - and new soundtrack :) I have the 70-300mm and was thinking of getting the 1.4, but now think I will just put the money towards a 100-400, or wait until Fuji announce their longer range lens. I will still keep the 70-300mm for all round portability / convenience while travelling. It is still a brilliant lens and mine does not suffer from the stiff zoom ring yours seemed to have. Your videos keep getting more informative and useful, and you wildlife shots are becoming better and better - keep going down this road :)

[@romanpul]

Just to point something out. TCs do NOT stop your lens down. Aperture is measured relative to the focal length. A TC changes the focal length of your lens, but the entrance pupil stays the same. Hence a pupil of diameter 50mm gives you an aperture of f/4 at 200mm focal length and when you add a 2xTC it gives you f/8 at 400mm. And since Tóneh comes from the size of the pupil there should be little to no difference between using a TC and cropping.

[@daweil94]

Thank you, missed this comment Also when cropping digitally in Post you also lose the same "iso" because the same noise is related to a lower area. Literally the same difference between a big and a small sensor, it is a crop and you have less total light than before

[@anonymousl5150]

@@daweil94 Less total light is irrelevant, it's light density that matters. And that's exactly what f-stop tries to measure.

[@anonymousl5150]

@romanpul TC changes your light density, which is what we primarily think of when 'stopping a lens down'. Yes it doesn't change the depth of field, assuming distance from the subject is exactly the same, which is the 2nd factor (not just entrance pupil size) to depth of field. All TC does is it magnifies the light and projects it into a smaller image circle and you lose light density in the process. The exact opposite happens with a speedbooster, where you gain f-stops.

[@tectoramia-sz1lu]

When I bought my 200-500 Nikkor lens, it cam with a 1.4TC. I use it a lot without any problems. The only issues that might arise is if you zoom in too far when processing. I also use a 2xtTC with my Z mount 70-200. That works extremely well too. I wouldn't be without them.

[@Group51]

I did no lab tests, but my most exciting moment with cameras was using the digital teleconverter at an Airshow with my Olympus. I was blown away at the details captured. I didn’t realise it was digital zoom till later, but the difference was not distinguishable from my eyes.

[@KurtisPape]

Interesting tests! I got a Sony 1.4x teleconverter for my 200-600mm and no joke it was a game changer for me. As a bird photographer trying to pick up fine feather details with large crops, it allows me to pick up those finer details by having more pixels on the bird, yes it is softer but once sharpened in post i have a higher quality image using the converter. As soon as i zoom my lens out it completely defeats the purpose of having the teleconverter though, so I have to make sure its always pinned at 600mm The fact that me and other photographers keep using the teleconverters (on zoom lenses) is enough evidence that they work even with the loss of light /sharpness, added weight, increased shutter speed needed, its still somehow worth it just to get those extra pixels on the bird, otherwise if the results were bad I naturally wouldn't choose to attach it...

[@ryankwan1934]

The 1.4x was a must have at Starbase, conveniently it's super bright most days so speed isn't a problem, since getting closer isn't a option zooming and cropping is needed to figure out what they are doing, I really liked having the 1.4 on the 100-400 and take the art pics with the 50-140

[@AstralLovelace]

I think probably what's going on with the 5.5x zoom on the 1.4 GM lens, with the lines that you can see with the teleconverter, but not the in post crop, is the difference between the resolving power of the lens vs the resolving power of the sensor. The overall image without the teleconverter is sharper, *but* those lines get lost between pixels on the sensor... maybe.

[@matthieurochette]

I just bought a 2x TC to put on the end of my Sigma 150-600mm. Why ? - 1. Money : less expensive than another even bigger lens - 2. Weight / volume : same, less annoying than another even bigger lens to carry around. - 3. One thing I noticed nobody is ever mentioning: the optical crop makes it easier for the camera to focus on small subjects at very long distances. So sure, the image quality may be similar, but when I got a bird (even a big one) so far out that my camera has trouble focusing on it (say, a bird flying in the sky, far away, and I want to shoot it with the background in a sort of "environment" shot), I think the TC will give me the optical reach the camera needs to actually make the focus work better. At least that's my hope.

[@alanhoughton6166]

all of these points are valid, but I would especially call out the 3rd point. I use teleconverters constantly for birds and if I'm not close enough, I just don't get the focus where I want it to be. I will add, though, that using professional level prime lenses makes the teleconverter a viable option. My favorites - Nikkor 300mm f/2.8 Ai-s, 400mm f/3.5

[@gerardferry3958]

1.4 is ok. cropped sensor better and 2x is a glass jar on a mount. teleconverters give you grain advantages

[@puffinspictures]

I find they have a purpose...sometimes. A more unusual use was on a pelagic birding trip where most of the birds were waaayyy out to sea and sometimes rather tiny. A 1.4x on a Sony A1 with 200-600 made many of the birds just large enough that cropped in 100% we could positively ID some sketchy ones after the fact (most people on the trip were strictly birders). And if I didn't have it on I wouldn't even have a "prove I finally saw it" shot of my favourite bird's behind as it flew away from the boat. In the right conditions, from an image quality perspective, you can't tell one was used. In the wrong conditions... "dammit why didn't I remember to take it off!" Just gotta know your gear and have realistic expectations.

I initially also thought that the teleconverter is less sharp, but looking at the crazy punch ins it seems like the teleconverter gives a softer image with MORE detail, which seems counterintuitive. So like yes it's giving more detail, but if you can't see it without cropping in like crazy, what's the point? Unless you plan to sharpen in post and then maybe the teleconverter just wins.

I ran similar tests with a rented Sony 100-400 GM and a 1.4x but only with photos. I rarely do video. On a bright sunny day all things being equal the 1.4x vs cropped were about the same, similar to your results. But a Sony 100-400 with 1.4x vs the same focal length on a 200-600 (both at 560) the 200-600 was clearly sharper. On cloudy day with not the best light, the 1.4 was basically useless at at 560 MM for photography. The ISO’s were so high or I had to lower the shutter speed too much for taking bird photos. So I agree there is a place for Tele’s under the right conditions but if you’re on a budget, crop. I also compared shooting my A1 in crop mode vs using the 1.4 x, at the same focal length and Fstop , I found crop mode to be slightly better.

[@EngineeringSiblings]

on the "35" the focus plane was a little different. :) thus on one lines were visible and on the other focus was n the "grain" of the paint.

[@CollectiveMindz]

The 1.4x is definitely sharper than the 2x. When you use a 1.4x teleconverter on say a 2.8 lens and you open up the aperture all the way and it says f4. It is just displaying the 1 stop light loss you are still technically at f2.8 but you lose a stop so it will display f4. You aren't suddenly at f4 depth of field. If that makes sense.

[@allankcrain]

No, you're not at f/2.8, you're literally at f/4 with both the depth of field and light loss implications. The f/number of a lens is the ratio of the focal length to the size of the aperture of the lens (hence f/number--the focal length, f, divided by that number, gives you the size of the aperture). Adding a teleconverter changes that focal length, but it doesn't change the size of the entrance pupil, so the aperture ratio is literally and technically different. If you have a 100mm f/4 and a 50mm f/2 with 2x converter on it, those will give you the same depth of field at the same apertures.

[@CollectiveMindz]

@@allankcrain sorry but you are fundamentally wrong about teleconverters. They do not change the focal length of the lens. They simply increase the image circle projecting onto the sensor enlarging them. This factor of enlargement is based on the power of the converter, 1.4x or 2x. The light loss is based on the amount of light hitting the sensor being reduced via enlargement. 1 stop less for 1.4x and 2 stops less for 2x. Therefore you see a reduction in light but not a change in f-stop or depth of field.

[@allankcrain]

No, I understand that what a teleconverter is doing is enlarging the image from the main lens system by increasing the image circle. What I’m saying is that that’s is literally changing the focal length, and so that literally changes the aperture ratio, and so that literally changes your depth of field. And if you’re now thinking “But that’s effectively just cropping, and cropping can’t change the depth of field!” well, guess what, that’s exactly what I’m saying, and it does. Consider crop-sensor cameras. You get more depth of field with a camera with a smaller sensor. Why? Because either you’re using the same focal length and moving back a little bit to compensate for the crop (and moving back a little bit means you’re not focusing as closely, and that means you have more DoF) or you’re using an equivalent focal length, meaning a smaller focal length relative to the full frame camera, and staying in the same spot (and the wider focal length means you have more DoF). All that’s actually happening is the same image is getting projected onto a smaller sensor-a crop-but in practice, that affects your depth of field in exactly the same way as using a smaller aperture on a larger sensor would. Using a teleconverter is exactly the same, but in reverse. I.e., imagine you now take your teleconverted lens system and put it on a larger-format camera, like a medium-format system with a 0.7x crop factor relative to 35mm (exactly canceling out a 1.4x teleconverter). By the same logic above that shows how smaller formats have deeper depth of field at a given aperture and field of view, the larger format should have shallower depth of field at a given aperture and field of view. So when you put this hypothetical lens+tc system on the larger sensor, you’ll get the exact same depth of field and field of view as the lens alone would give you on 35mm, which means that the lens+tc system must have a smaller aperture than just the lens alone. You see the same thing again with “speed booster” adapters for mirrorless crop sensor cameras-they’re effectively just wide-converters, and the “speed boost” comes from the extra brightness you get by shining the same amount of light on a smaller surface area, but you also get the same depth of field that you would get with the unconverted lens on a 35mm camera, which is the same as the wider aperture on the smaller-format camera. If you really need me to, I can dig out my teleconverter and take some example shots.

[@CollectiveMindz]

@@allankcrain sorry but you are still wrong. You can throw down as many words as you want to make your point but you are arguing for the sake of arguing and throwing out miss information.

[@allankcrain]

@@CollectiveMindz If you can actually lay out a logical argument and show me that I'm wrong, I can totally accept that I'm wrong. I'm not just "arguing for the sake of arguing" here, though, because in addition to my logical argument, I tested it in the real world with an actual teleconverter to make sure I was right. So since apparently you had trouble following my argument in one big chunk, I'll try explaining it to you in smaller sections. So: You understand that you get shallower depth of field with larger format sizes (e.g., full frame or medium format) than with smaller format sizes (APS-C, 4/3, cellphones, etc) all else being equal. Correct?

The difference in the fine lines of the aluminum brushing on the 35 might be a slight difference in focus: in some zones of the frame the no teleconverter shots look better and in others worse, most of the time no difference worth the price.

[@Scyth3934]

SHARING TO LET PEOPLE KNOW MY EXPERIENCE: The Canon EF 1.4x II on the EOS R with the Tamron 70-200 G2 (at 200mm, applicable to all areas of the frame) displays *very* slight increase in detail (due to not having to crop) but that is cancelled out in my opinion by a very slight drop in contrast as well as a doubling in chromatic aberration.

[@pspicer777]

I might be missing something here, but the teleconverter gives you more resolution per magnification. You are imagining a larger (magnified) image on your sensor. So you will have more 'room' in post to crop etc.

[@drdomestos]

So, would the conclusion also be, get a GH6 and use the Leica 50-200 (rather than the 100-400) and crop in post where needed? Or even use Digital zoom in the camera?

[@halfalligator6518]

For video this makes complete sense, because you already have enough information when cropped (so long as the main lens is high-resolution enough to land the light on that sensor making use of every pixel. You simply can't beat pixel perfect sharpness. The TC might help with photos on some lenses on some sensors and with some settings - but not always. Especially not with video which is relatively low-res. I had the same issue with my FF Nikon setup. My FF 300mm prime + TC1.4 had the same reach but a less clear image compared to using the 300mm on a crop-body WITHOUT the TC. I wasted $450. This is because that particular lens was so sharp the FF sensor was not even high resolution enough to get the most "potential" out of that lens. Simply increasing the density of the sensor (with a crop sensor) managed to utilize that extra sharpness that was just "hiding" in waiting. No TC necessary. I think this is mostly a "problem" when your lens is super sharp already though. It's always best to increase the sensor density up until the lens is no longer over-powered. Much better to do that if possible than use a TC. Your sensor even while cropped in post, was still 4k, and the lens (without TC) was more than sharp enough to provide pixel level sharpness for that cropped zone.

[@officialtiimo]

I have the exact opposite take, re: photo vs video TC performance, because cropping in on a compressed video in post also crops in on lossy compression and artifacts. With a photo you can just shoot RAW so the compression artifacts are not really baked into your shot when cropping.

[@halfalligator6518]

@@officialtiimo i'm not sure that would be the case though... because the compression comes after the light is captured by the sensor. All my points are relating to that prior process so any compression would happen the same with or without TC

[@philsag]

@@officialtiimo Same here. For video there's only so much you can crop in because the image (usually) is already low resolution compared for photo. Unless you're going 8k to 4k or 4k to 2k output it just ends up looking blocky and pixelated if you crop to far. Slight softening from a teleconverter is a better trade off if light allows.

From my experience : a TC 2X will bring a significat plus in 15-20% of the situations, while in 80-85% will make it worst than lens alone. And of course the 2X TC has to be mounted on a fix lens (F/2.8 or F/4.0) which has a good resolution and use it in good light only. In this way the impact of the TC is minimum. When the TC it's mounted on a zoom which eventually is soft wide open, the result is easy to be predicted.

They work great on the Sony Gm prime lenses with no quality loss with the 1.4 and barely any with the 2x.

[@chefineer]

The times when it probably would make a difference is if you shoot jpeg with sharpening. The sharpening process usually includes 'edge enhancement' which will add a tiny line of white pixels around (for example) the edge of black text. When you zoom into that then the pixels increase in size, the enhancement effect becomes more obvious, but...only if you use a loupe

[@summolibritor]

I bought the 1.4 teleconverter as part of a deal with the 100-400. It didn't take long to figure out that the converter reduced the quality of the images to the extent that I do not use it at all. I have seen it mentioned that the converter performs better with the new 150-600 although we will have to wait for some decent independent reviews and testing after the lense has been officially released. I'm still using the XT2 for my bird photography and was thinking of migrating to Canon. I've decided to sit back and see what the XH2s/XH2/150-600 brings to the table.

[@alansach8437]

To be fair, teleconverters were never designed to be used with zoom lenses. They were designed to match with premium fast prime lenses. When used with zoom lenses, the image quality of which doesn't match the fast primes to begin with, you do so at your own risk. Having said that, I have successfully used a 1.4 with my Canon EF 100-400 ii. The difference in image quality was acceptable, though not as minimal as using it on my f4 primes.

[@kenfrank2730]

I'm generally not a fan of TCs, but with one exception. When I use my Canon EF 300 f2.8 IS II with the 1.4x it still retains superb IQ and AF performance. Can't tell a TC is attached. But that was a $6k lens.

[@pedrosanchez4035]

Great tune - great video thanks

[@bigshooter461]

Great footage, that Female Blackbird perched in the Bullrushes was fantastic. I think the teleconverter definitely serves a purpose you just have to understand the difference between using all the sensor with a converter and a portion of the lenses visible field of view, or cropping the sensor. With the right lens at the right appeture the teleconverter might be a better image, especially in video where the resolution is already much lower than with stills. Cropping in on 4k isn't so bad but cropping in on 1080 does get a little grainy sometimes, but not always. I would say keep the converters it gives you options. You don't have to shoot with it. I enjoyed the music as well!

'You don't have to shoot with it'..... it would make a really expensive paper weight. But stylish of course.

[@bigshooter461]

@@ItsWhatIDo I never suggest not using it only that you don't always have to, I think I made the point that it definitely had a time and place, his footage clearly displays it's value!

[@JohnDrummondPhoto]

The 2X teleconverter is a waste. 1.4x is useable, though not ideal. The key is, you still have to get closer. Go back to the waterfall shots. Look how much heat wave distortion because you were so far away. That will affect your bird photos also. So keep learning how nervous your birds are and how close you can get. Try shooting in a botanical garden. Birds there are more used to non-aggressive humans and may let you get closer. Good luck! P.S. the blackbird in the reeds is some of your best footage yet. That's from getting closer. Luckily, red-winged blackbirds aren't very shy compared to others.

Interesting tests for sure. And I'm liking the new song! Can we download it from your Stern Beats page?

[@AlpacoFilms]

Great tests, dude! I think the benefits are mainly if you shoot photography. I definitely don't see a big enough benefit to use a TC for video. With photos you you get the advantage of using the sensors full potential and full resolution. With video (even when downsampled) there's lots of compression happening. But I'm no professional so I could be just talking out of my butt.

[@jonnyfez]

It depends entirely on what you are doing/using. I use a 300 f2.8 lens on a D850 (46mp). If I add a 1.4x I get effective 420 f4. I could leave the f2.8 and zoom in post and crop. But with the TC I still have 46mp to play with. The optics of the 300 f2.8 with the 1.4 are completely fine and focus/tracking is still fast. I do not see how I can achieve this other than carrying a 300 f2.8 AND a 500 f4 together. No way. The 300 + tc is great. Very flexible. Not much loss in quality and still 46mp. The TC was not expensive. No brainer for me.

[@thomasmaughan4798]

Precisely. You need lenses good enough that extending them you still have quality.

[@tauaklonowski]

with the teleconverter.. there's more background compression.. only real gain and diference I could notice..

[@robertlosch4797]

The use of a converter makes sense in some cases and in some not. I will explain 2 cases, a converter makes sense: 1. If you are shooting with a "lowres" camera (around 20 MP like lots of the pro cameras for sports events), you don't have much left for cropping in post. To maintain a reasonable amount of resolution, you can use a converter. So: Using the converter depends the optical qualities of the converter and the lens attached, using "post crop" depends on your sensor's quality. But this also means, that there could be bigger differences in quality with another lens-converter combination that might result in a big plus for the use of converters as well. 2. If you are working under time pressure or have other reasons for not doing any post production... Well, that's self explaining, I guess. But yes, the primary question always is the build quality of the converter. If you take Canon's EF 2x III extender, you might want to kick the image into the bin afterwards. Whereas you use the EF 1.4x III (or one of the two RF extenders) instead, you will jump for joy. So, if you want to use a converter, always take your workflow and your working equipment into full consideration, because the decision to buy/use a converter always is very subjective.

[@skyrunr]

Great video and comparisons. I believe focus accuracy/performance decreases on mirrorless when using a TC due to less light hitting the sensor. Nikon Z lenses have less compromise with their TC's. If you can get even your hands on a TC.

[@officialtiimo]

The 1.4x seems like a better compromise. I did notice that the 1.4x was a bit sharper in the duck shot vs zooming in. More importantly I saw much fewer video compression artifacts because when you crop in post you are also zooming in on artifacts and the compression has happened before the zoom. When you use a TC the magnification happens before the light even hits the sensor. So I do think it would be worth using in some situations. The 2x doesn't seem worth it for the noise and AF issues.

[@WesMann]

I've started using a 1.4 teleconverter to make my wide tilt shift lens less wide. I suppose your point is that the 1.4 could be applied in post to achieve the same result. It is nice not to have to fiddle with the digital zoom on the camera to see what the 1.4 crop in post would look like... so 1.4x makes shooting faster. I've been running the 1.4 for real estate shoots and only taking it off for extra small rooms. Also means I don't need to manually crop in post. Of course this is still photography with a tripod and flash.

[@scgb5]

The tests were pretty good as it's typically dark (ish) outside. but the teleconverter image would look better if it wasn't running at such a high ISO. That said, everyone (you, Toneh, Jared), doesn't seem to know that real wildlife photography occurs in the earliest hours before the sun is really up. Need that fast super tele

is the zoom not doing artificial scale? our computers and browsers are doing automatic text anti-analyzing, image software is doing it any time you zoom.

Congratulations on your discovery of Brick Works' majestic and natural waterfall! Also, screw you for spotting TWO kingfishers when I only spotted one and couldn't get a single photo of it.

[@perpetualflame]

I think I've mentioned before. But if you have high pixel sensor then a teleconverter would only diminish your quality. Because of the extra glass but also the extra stops of light you lose

[@kchambers8102]

Pix awesome. Music awesomer ! Is that a word, don't know maybe I should look it up. Did you really create that? I don't know but maybe I'm getting addicted to your videos, I'm not sure... don't hold me to it.

[@skylar767]

Mom's safe. I watched the whole Damn thing.

[@wateaman]

Years ago I had the opportunity to test the latest version of the Canon 1.4x teleconverter before buying it. I used a tripod and optimal lens/ISO settings to shoot dozens of pics with my Canon full frame. In the end, I could get sharper results by cropping the photos without the converter to equalize the image size with the converter. Didn't buy the converter. Empirical confirmation of Jared's genius?

[@dct124]

Pretty much why camera brands put in camera cropping into the bodies. I think Leica made the best use of cropping with the Q2.

[@garfieldirwin]

Not sure the concerns about ISO penalty when shooting video outdoors with TC? Adding a TC just reduces the need for an ND filter -- ISO shouldn't be a factor. Stills are a completely different matter of course.

[@GlennFamilyChannel]

The advantage of the TC for me is seeing my subject better (birds) a little better while I’m photographing them even the there’s little gain in post.

[@DeputyNordburg]

Essentially the lens has to be so sharp that your camera can't capture all of it's detail. With the high MP cameras we have today, that is a small set of lenses. I have a Canon 600mm f4 IS II, and I've sent it in to canon to be turned. I get noticeably better detail with the 1.4X and 2.0 X VIII extenders when shooting the same subject (like a bird) from the same distance with my 45MP R5. Now if I could get 2x closer to the Bald Eagle, that would be better. If I could get 200MP that would be better. Back int the days of film or 4MP DSLRs, a teleconverter probably gave more detail on Andy decent lens, but today with MP galore...

[@Delphisteve]

First of all, teleconverters work best with prime lenses ON A TRIPOD. Second, you need to used both hands on camera and lens and apply pressure to facilitate vibration. Using a teleconverter with the right technique should make your magnified Image sharper then cropping in post because w/ converters you put more mega pixels on your subject ...!

[@Alseki7]

As per my comment previous video, TC only worth using if the lens is sufficiently sharp that when used natively you could crop to or close to the sensor resolution while producing acceptable images. When used at 400mm focal length the fuji 100-400 lens just isn't that sharp. Whereas for e.g. 80mm macro or 50-140 the 1.4 TC can have some niche value.

[@jameskurzynski2386]

I'm not a tele user, but I was actually surprised how well it worked. What I did notice is that your comparison was cropping the non-tele to match the tele. What I presumed you were looking for was a tele so you could crop the tele to get even closer. Perhaps you did this already or I missed it in your examples (don't come after my mom, I watched your footage... nice song), but what I would be interested to see is 400mm + 1.4 tele (600mm) cropped another 1.4 vs. 400mm no tele cropped 1.4 x 2. That test, to me, would show better if a tele is worth it. To me, your tests simply showed that the difference between a non-cropped tele shot and a cropped non-tele shot are basically the same.

[@jameskurzynski2386]

Opps... You did do this.... my bad. sorry.

[@jamesoliver6625]

You're now talking of what I observed, as a "picture taker", and why I've decided to remain in the DSLR world and using "vintage" glass. If you buy quality vintage glass, at an extremely attractive price, and compare the nuances ($450 lens vs $2400 lens), the differences don't justify in the economics of my world. And if I need that tiny difference (product photography of jewelry), I can grab a different macro lens that I got years ago at a third the price.

[@1armbiker]

The only reasons I could justify getting a 300mm 2.8vr over my AF 300/4 was weather sealing, the VR, and the newer coatings. The extra stop and faster focus were nice, but realistically the 300/2.8 is 95% to perfect and the 300/4 for 1/10th the price was 85-90% perfect.

[@jamesoliver6625]

@@1armbiker sort of been there. I have the 300/4 (no VR) and at my age to use it I ride it on a monopod (I shoot a lot of grandkids youth sports). The 2.8 would be a balance nightmare on the monopod but when properly used, the f4 is beyond what any sold photos have needed ("baseball cards" of their kid in action) AND I got it for a song.

I think teleconverters are good for macro, but not much else. Maybe that slight but more is worth 400 whatever dollars to someone, but not for me... Except when I sit macro. I love macro. Slugs are actually pretty colorful up close.

[@sunny8784]

one thing he forgot to add..when shooting birds, you do crop your images quite a bit in some cases. With the TC, you have more room to crop, without, less room to crop. with todays cameras and post editing software, teleconverters will be more prominent.

[@douglasstemke2444]

I wonder if physics becomes an issue with a TC do you start to get refraction artifacts that would amplify as the lens stops down. The place this might be an issue is macro if you wanted more reach and have more dof
