Fujifilm 70-300mm vs 100-400mm for Wildlife and Bird Photography (tested with X-S10 and X-T4)

[@bahrambahreini732]

I'm a newbie to Fuji from the Canon world with 20 years experiences. After watching this video, I realized that choosing S10 + teleconverter x2 + 70-300 was a right and smart choice. I am very excited about shooting with Fujifilm and really love it.

[@peterscott-jones9998]

I take my 70-300 out along with a 1.4 TC and throw in a 23mm F2 and find this makes for a light weight wide choice system. I love my 100-400 too but this is mostly used for special occasions such as Wetland Trust days. They both take great pictures attached to my XT3. Thanks for your great review(s), please keep it up 👀👀👍

[@davegarth]

I’m an older but still active retired photographer. I owned the 100-400 for years and really liked the results. But, at my age (76) size and weight becomes even more of an issue. Specifically, I found my age-limited hand strength made handling the 100-400 gradually less comfortable, caused by both the weight and the girth of the lens. I never dropped the lens, but I worried that I would, and that took away a lot of the fun. Interesting, my younger friends who used my lens felt the same way. The 70-300, on the other hand, is just the right size and weight to make the entire photographic experience a pleasure again.

[@mikefoster6018]

Great stuff. Today I took out my new 70-300mm for the first time. I'm 48 but was also worried about general weight, as I want to carry two strong lenses. I htink my X-T5, 16-55mm and 70-300mm are going to be a fantastic combination that I can just about happily lug about in my backpack in the countryside. For urban situations or at night, I'll probably carry the f1.2 56mm instead of the 70-300mm.

[@catherinegrimes2308]

In the autumn of 2022 when I 65, I went to the local camera shop to buy a long focal length zoom lens and there was a choice a new 70-300mm or a used 100-400mm. On lifting the 100-400mm, it didn't seem to be too bad but when I put it on my little X-E3 I knew that it would be too heavy to comfortably manage. The 70-300mm was the correct choice and I can walk a mile to a nature reserve, take some photographs and walk back without being bothered by the weight. When flying to Gran Canaria for a holiday, the camera in a camera bag along with the 70-300mm lens in its case easily fitted into my backpack on the flight.

Most complete review of these two lenses so far. Pointing out details others missed. And well presented with informative graphics. Many thanks for being so thorough!

[@MathieuGasquetMirrorLessons]

Thank you for the kind comment.

[@robertbirnbach2312]

for me as someone who shoots both FF and Fuji APSc the smaller lens is my preference. I take the fuji when I want less size and weight which to me is the main advantage of the system. thanks, for the detailed review it told me what I wanted to know and that is optically the 70-300 is on par with the more expensive lens.

[@enigmabletchley6936]

Thanks, Matthieu. As someone who already owns the 100-400 I don't think there is an advantage to me also owning the 70-300. However, as soon as the 150-600 turns up it will be bye-bye the 100-400 and I may 'backfill' the range with the 70-300 at that point. The information on the use of TCs is very useful. It confirms my results with the TCs on the 100-400 so it is good to get a second opinion.

[@MathieuGasquetMirrorLessons]

Thanks, glad that my findings match yours. Looking forward to try the 150-600mm.

[@ksnmurthy4476]

As I mentioned earlier, I bought this 70-300 lens. There is some initial focus hunting problem. Once it’s fixed it’s easy and nice to use. Thanks for the impartial review. 🙏🏽👏🏽

[@MortAllachie]

If I was buying one of these lenses today, I would have gone with the 70-300 because of the size and weight. But since I already had the 100-400 when the other was released, I´ll stick with it. Thank you for the great review 😊

[@longboardfella5306]

Excellent reviews thanks. One reason for the slower autofocus with x2 convertor on the 100-400 is that I've read it disables phase focusing and relies only on slower contrast focusing. The x1.4 still enables both focusing modes to be active. So I now only use the x2 in really good light. I'm really overall happy with the light weight and performance of the 70-300 on my x-s10. I returned the 100-400 as I could only use it with tripod.

[@MathieuGasquetMirrorLessons]

It depends on the camera. The X-T4 and X-S10 maintain phase detection at f/11 if I'm not mistaken (if it was contrast detection I would have noticed a much bigger difference, as well as a different behaviour with the movement of the lens elements).

[@ronallen94]

I have an Xt4 and I pair it with the 70-300 and1.4x teleconverter. I find this good enough for my wildlife photography as I usually get good quality images. The close up capabilities of the 70-300 are also a great feature. It is a lightweight set up which is good as I’m now 68. Sure, there are times when I could do with more reach but the 100-400 is too heavy and pricey for me. Perhaps a 2x teleconverter is the answer for mr. Thank you for this video.

[@jamesmlodynia8757]

You can use most telephoto lenses for wildlife photography, some work better than others, the 70'-300 works well on a APSC Camera body, I have used glass like this photographing birds and wildlife from a 14 foot kayak. While some people use a teleconvers on this type of lens, the loss of light can be a problem if you are shooting in low light such as early morning or evening hours when some wildlife and birds are most active. This morning while out walking my dog, I brought along my XH2 with the 100-400mm fujifilm lens. I was able to photograph a great blue heron feeding in a creek that is located on the perimeter of the park I walk my dog in, my Iso was 5000 ,exposure compilation -1, I was just able to get fast enough shutter speed at f 5.6 as long as the movement was at a minimum, later on I photographed a fawn that still had its spots feeding along the same creek. There are times when I find nothing as far as wildlife goes to photograph and days like this morning when things are great. I carry this camera setup in my vehicle as I never know when a photography opportunity will present its self. While the 70-300 is lighter,less expensive and more travel friendly, the 100 to 4oomm lens is a much better option for wildlife.

[@MathieuGasquetMirrorLessons]

[@ralphn8948]

This is so helpful, thank you. I have the 100-400 but find the weight discouraging to carry especially when out on my bike. It sounds like the 70-300 with/without a 1.4 converter might encourage me to pack the camera more often rather than resort to a hybrid.

[@gerriewessels9690]

I've wanted to upgrade my xt10 & 55-200 for something suited for birds, your review has helped met to understand that XS10 & 70-300 is indeed a worthy alternative to XT4 & 100-400 is not the only. Your reviews are great!!

[@martinyip65]

Excellent comparison, Mathieu ! Very helpful and should be of great interest to those with this exact dilemma. Personally i have an XS10 and the 100-400 but was very curious as to how the 70-300 compared.

[@frankbrune3101]

Tank you for the conparison. Two things specially stood out to me, the comparision of the fields of view and the effort to have the top budget and top of the line body side by side. Tank you for that!

Glad you enjoyed it!

[@QuickQuips]

Great video. Unless I find the 100-400 used at a good price I think it makes more sense to skip and go for the 150-600 or do a 70-300 plus 1.4 TC.

[@joao.s.cardoso]

Thank you for the really good review. I have both, The 70-300 is better for travel or when you want to be lighter but the 100-400 is the best lens by a good margin. Not only for the 100mm extra reach, that allows you to be closer and have mode blurry background, but also the tripod collar makes a huge difference when using the tripod as its a much better balanced system. So for travel and the dayts I dont want to carry my main camera bag I use the 70-300. When I do want the absolute best IQ and experience with a Tripod (Landscape photography for example) I take the 100-400,.

[@jadeEpeace]

Thank you so much for this detailed review. I found it very helpful for choosing which lens to get.

[@julioareck]

As always, excellent review. As an amateur travel photographer, I prefer lighter and more compact gear, so the 100-400mm is not my cup of tea, and I guess the upcoming 150-600mm will be even heavier and bulkier. I have the 55-200mm which is OK but sometimes I need more reach, so I intend to get the 70-300 (and the teleconverter) in the near future.

[@Maxmaxs5]

I luckily bought my whole Fufjifilm setup just a few weeks before the 70-300 dropped and was able to return my 55-200mm after buying the 70-300mm, and I couldn't be more happy with it! They're practically the same exact size/weight/everything, just with better more modern quality and longer reach. The 70-300 never ceases to amaze me with the quality I get out of it, hope you have a good one with it too! 100-400 also too big for me

[@amitkrupal1234]

Most detailed & apprehensive review. Awesome thanks for tour efforts & uploading this video

[@tomleo4670]

Another awesome video, thank you so much for the detailed comparison, Mathieu! I walked around both lenses for a long time, but in the end I opted for “you cannot have enough reach” 🙂 and for wildlife 100mm more or less is huge. I got luckily a great deal on the XF 100-400mm plus 1,4 tTC and so far I am really happy with the lens. I am using a gripped X-T3.

[@JeffreyHauser]

I also use the XT-3 with the battery grip & 100-400mm. I find this to be a good combination with a nice balance- although it is NOT light weight. If I need even longer reach, I attach the 1.4 tele extender, losing 1 stop of light. All in all I am satisfied with this setup & the optical stabilisation on this lens is very good & much needed at these longer focal lengths. Love your channel, Mathieu!😊👍

[@bill3117]

This review is the best I've seen written or via video! I recently purchased a used 100-400mm (to use with my XH-1 and XPro3) after giving up on obtaining a in-stock 70-300mm.So, the XH-1's stabilization is not additive to the 100-400mm stabilization? That is disappointing! I hope there will be a firmware update for the 100-400mm that will fix that. I'm not so sure the price difference was totally worth it (for my amateur use) by going with the higher priced 100-400mm, but I am very satisfied with the the 100-400mm. PS. Great conclusions!

[@MathieuGasquetMirrorLessons]

I think it’s probably related to the X-H1 ibis rather than the lens, but I could be wrong. That said, with those long focal lengths, the OIS plays a more important role anyway.

Very good comparison between the lenses! Thanks a lot for the video! I'm very happy with my 70-300mm for it's nice small size and light weight but knowing the difference with the Fuji 100-400mm is good. :-) I believe that Fuji is working on a 150-600mm lens, I'm looking forward to that and curious what it will bring.

[@fujiwildlifevideography9288]

I've been using the Fuji XT-4 for almost two years now with the very compact and budget friendly XC 50-230mm f/4.5-6.7 (I know a bit slow compared to your telephoto lenses :( but still capable of producing amazing wildlife videography!). This camera and lens really jump started a new hobby for me since the start of the pandemic. I've been particularly pleased with the stabilization but of course low light scenarios can be tough when limited to f/6.7 (really need to crank up the ISO). Nevertheless I’ve really enjoyed getting outside and capturing some beautiful Ohio wildlife. I plan to share some of my work on YT soon. First video is already up!

[@MathieuGasquetMirrorLessons]

Nice video. How much stabilisation in post did you need to add? The shots are very stable.

[@RVNmedic]

Very nice. Now I'm really torn as to what to buy. I really want the 100-400 but the size, weight and price difference is substantial.

[@thomashill5768]

I have the xf70-300. I like it, I'm pleased I bought it as I like the size and focal lengths, but it is soft as pudding! Uncropable! To the point where I'm wondering if I have a lemon on my hands. I've experimented with shutting off the ois at high shutter speeds but have had mixed results. I wish they had kept the ois switch on the lens and losing focus catastrophically when you zoom in and out gets old quick. If you're just getting in to photography I think you'd be better off just grabbing an xc50-230 off ebay...

[@MathieuGasquetMirrorLessons]

The first sample I rented had a serious optical quality issue, the images were just too soft. Fortunately the rental company had a second sample and they exchanged it right away. I thought it was just bad luck at first, but now I wonder if you got a bad copy and there are some quality control issues with this lens.

[@thomashill5768]

@@MathieuGasquetMirrorLessons That's interesting. What would you do if you were me? Is there somewhere to send it to see if it's deficient? I'm in the US...

Have a look on the Fujifilm US website, I’m sure there are some support/repair centers in the US. If you think that level of softness is not normal, it might be worth to ask them. When / Where did you buy it?

[@faisalsheraz8101]

Excellent comparison of these two lens...

[@RichardSilvius]

This is by far the best and most detailed comparison I’ve seen regarding these two lenses. Thank you! 70-300 looks like an incredible value by comparison. One thing you didn’t cover in your review was precision framing while on a tripod due to sagging caused by the front heaviness of the lens. With the 55-200 this is super annoying at the long end, and I imagine it would be even worse at 300mm. For some, having the tripod collar to reduce or eliminate that problem might make it worth paying double for the more expensive lens. The sagging is THAT annoying. It can cause you to miss shots - for example a distant landscape with rapidly changing mist or clouds could go from the perfect composition to complete trash in a few seconds - seconds you could lose trying to achieve the desired framing with one of the non-collared lenses.

[@MathieuGasquetMirrorLessons]

Thanks! About the sagging problem, isn't it also related to the quality of the tripod head? There are also lens support brackets that could solve the problem.

[@RichardSilvius]

@@MathieuGasquetMirrorLessons I'll have to look into those brackets, I had not heard about that. As far as what causes the sagging... it's hard to pinpoint. I was using the appropriate Really Right Stuff ballhead for the weight of the camera and lens - a little overkill actually. But have also experienced the same using a manfrotto head designed for much larger cameras. While I can't rule out the heads, it seems to me to be the lens itself when fully extended. Maybe there's a tiny bit of play in the construction that allows it to happen... I'm not sure.

[@rogerhampton2844]

You could try a geared head?

[@hackerblubb]

thank you for the comparison! i own both lenses, with the 1,4x TC, but the 100-400 doesn't get much use because of the weight & size (at least when casually travelling or hiking) so right now the 70-300 with TC is kinda glued to my xpro3 and it feels so versatile to the point, where i don't know if i should even keep the bigger brother "just in case you need it one day" :) your comparison images were very good, thanks again!

But I have not seem a creditable review of the lens for BIF etc. One thing I cant find out about the Tamron 18-300 is if the IBIS & OIS work together or not

Great review. Thoughts regarding the 1.4x Vs 2x teleconverter? 2x better reach but potentially worse image quality (lower light) so 1.4x perhaps a sweet spot?

[@MathieuGasquetMirrorLessons]

The 1.4x is the sweet spot for sure, unless you really need the extra reach. You loose a bit of sharpness with the 2x but it’s not terrible.

[@ZemiEmperor]

Wow, wonderful review, also graphically! To make sure, could you clarify if using in-camera IBIS makes a difference to using the lenses? I assume that it must make a difference but it is really so and is it significant?

[@MathieuGasquetMirrorLessons]

Practically speaking, I don’t think it makes a relevant difference. At 300mm or 400mm, it’s mostly the OIS on the lens that counts.

Thanks for the review and setup tips! I just received my 70-300 and am very happy with the image quality. I did, however, notice quite some noise when the lens is focussing (not the stabilisation). Is this normal? Thanks in advance!

[@MathieuGasquetMirrorLessons]

I don't remember having a lot of noise with my copy. Is it really loud?

[@te4743]

Thanks for the reply! Appreciated. I’m not an experienced Fuji user. But yeah, it’s a lot louder than, for example, the 16-80. Sounds like beeps from an old router. If I lock focus in continuous and then slightly move, it makes a lot of sound. Don’t think this is normal? Maybe I’m too picky.. I’ll let someone in the store take a look at it.

[@urbansoban2669]

Thank you very much for this very informative and well-made video. What puzzles me though is the photos of the eagles with the 70-300. I have the same lens and an X-T4 and there is no way I could get such impressive shots. How far from the birds were you and what kind of post-processing did you do? Kudos!

[@MathieuGasquetMirrorLessons]

At the red kite feeding station, you can be reasonably close (very close if you go to Gigrin Farm in Wales). No major post processing, just basic adjustments. I rarely spend more than a few minutes editing a photo.

[@funkyboogiee]

I have the 50-140mm which I do like a lot. it get's decent reach with the 1.4x TC. I've heard the 100-400 has even faster AF than the 50-140mm. is that true? the 150-600mm has my attention, but who know's when it will be released this year. I'm torn on getting a used 100-400mm or the 70-300, which probably will only be good for bright days if the 1.4x TC is attached to it.

[@MathieuGasquetMirrorLessons]

I never tested the 50-140mm with birds, but I used it several times for sports events. Not sure if the 100-400mm is faster, I find both really good and on the same level. I guess the 150-600mm will be announced alongside Fuji's new flagship X-H2 in May (according to Fujirumors), but we'll have to see for the release date. You can take more than decent photos at f/8 as long as the light is acceptable, even in cloudy days.

[@funkyboogiee]

@@MathieuGasquetMirrorLessons yeah I've gotten great birds in flight with the 50-140 with the 1.4x TC, which of course bumps up the aperture to f/4 through about f/8 where I'd shoot. Of course the reach isn't crazy far but that lens is certainly one of fuji's top lenses! It's not necessarily in the sports, action, wildlife range but if you are close enough then it absolutely can do it very well. I'm just torn on getting a used 100-400mm, or a new 30-70mm while I wait for that 150-600mm, because it seems like it could answer a lot of our needs! who knows what the price of this new one will be though? Could be close to 2k, or more??!!?? anyone heard any predictions yet? kind of bummed that it may be late may or June,or later by the time it would be released.

I use the 50-140 +1.4 teleconverter but I would like to get more reach to avoid cropping in the edition. I have a doubt about the focusing keeper rate of the 70-300, when you have to change quickly the focal length ( when the soccer striker is coming in your direction) and just after changing the focal length, when you have to use the continuous focus.

I am at crossroads to sell off my XF100-400 and keep only XF70-300 (that I bought after reading your review last year). I can see a frame in your video where you have attached 2X TC to 70-300. How is the picture quality of this combination? If I got a 1.4X TC I could get the similar reach with XF100-400 in the longer end. So if to keep it or not?

[@MathieuGasquetMirrorLessons]

The performance degrades a bit with the TC 2x, and so does the optical quality. It's not terrible, but you can notice it. I think 70-300mm and TC 1.4x is the better combination.

[@MathieuGasquetMirrorLessons]

I’ve had better results with the A7 III overall. With Fujifilm cameras, it is also a matter of finding the right setting combination. Fujirumors mentioned a new camera coming in May and it should be a new flagship (X-H2), so hopefully we’ll see an updated AF among other things.

Hello from Belgium, I have the combo X-S10 + XF 70-300 + 1.4 TC I'm verry happy with this set I would like to buy an 2.0 TC but I'm afraid the picture is bad...or wait the 150-600 mm Sorry for my english ;-)

[@MathieuGasquetMirrorLessons]

You loose a bit of sharpness with the TC 2.0x (you can see examples in the video) and the fastest aperture at 300mm becomes f/11, so you will need decent light conditions to get something out of it. But it is an affordable option to get more reach. Or you can stick with the 70-300mm + 1.4 TC and use the 1.25x crop mode in camera, or crop in post (if you're not doing that already). We need to wait for the 150-600mm, but I suspect it will be large and expensive.

[@chodzsiepowoczymy1892]

Fuji xs10 with xf70-300 or Sony a6400 with sony 70-350 would a better option for compact wildlife system? My friend asked me what he should buy for wildlife, he often takes a camera on bicycle so it have to fit into handelbarbag. I'm landscape photographer and fuji user but from what I've read a6400 will have better AF than Fuji. If Sony really has better AF is 70-350 a good enough lens compared to xf70-300? I worry that Tamron 150-500 which would be a perfect fit for a6400 will not fit in his handelbarbag :p

[@MathieuGasquetMirrorLessons]

The Sony has a better AF overall, but I have no experience on the 70-350mm lens. With the Fuji, there is compatibility with the teleconverters which can be a nice thing to have the day you friend wants more reach. What are the bag's dimensions?

[@chodzsiepowoczymy1892]

@@MathieuGasquetMirrorLessons thank you for reply. The bad dimensions are: 23x15x16 cm which is 9x6x6,3 inches. There is foam inside so dimensions aren't super precise

Teacher, may I ask, I currently use x-t4, the lenses are xf16, xf56, xf70-300, I am sure to buy tamron 150-500mm, but I also like tamron 17-70 and tamron 18-300, if it is you , tamron 17-70, tamron 18-300, xf70-300, these three lenses, choose two or one, how would you choose, can you give me a reference??? Thank you

[@MathieuGasquetMirrorLessons]

I didn't try the 17-70mm and the 18-300 so I can't really comment on that one. It also depends what your needs are.

[@DjCjFoto]

Nice review...any chance to review Nikon 100-400s?

[@MathieuGasquetMirrorLessons]

Would love to, maybe coupled with the Z9 :-)

[@steviegriffin]

I own a x-t20 and I am very unhappy with the AF performance if there are branches in front of a bird - lots of AF hunting going on. this was more precise with my old Nikon D700. Is there much difference between an x-t20 and a x-s10 and even x-t4?

[@MathieuGasquetMirrorLessons]

Which settings do you use on the X-T20?

[@newsigmundfreud3023]

*Thanks. As many have asked in a different way I would ask like this: Can you do a 50-140 / 70-300 comparison?*

[@MathieuGasquetMirrorLessons]

I'll keep the suggestion in mind. But right now I'm working on the OM-1.

Very good comparison, can you make a video on bird photography with fujifilm X-H2S, thank you.

[@MathieuGasquetMirrorLessons]

Yes, I'll test the X-H2S, not sure when but hopefully soon!

[@driftinsider3392]

I shoot motorsport is X-S10 and 70-300 good idea? Or I should buy XT-3 (XT-4 is to expensive now) and 70-300 or different lens? I really want join to FujiFilm family.

[@MathieuGasquetMirrorLessons]

I think the 70-300mm can work well: fast AF, excellent quality. X-S10, X-T3 and X-T4 have the same AF system (Fuji updated the firmware of the X-T3 to raise it to the same level) so choosing the camera comes to the budget and features (for example the X-T3 has weather sealing, two card slots, better EVF). I'm assuming it's mostly outdoor motorsport?

[@DUCzillaMonster]

Thank you for the very informative video! Looking for more mm, i got the 50-230, but i think that 70mm extra is not that much, what can you say about that

[@MathieuGasquetMirrorLessons]

No 70mm is not a lot of extra reach. I would consider the 70-300mm if you wanted also to work with the teleconverters.

[@DUCzillaMonster]

@@MathieuGasquetMirrorLessons yes with 1.4 its even more then the xf100-400

[@miguelosvaldo]

Great review and comparison.

[@MathieuGasquetMirrorLessons]

Thanks!

[@edbertcadavero14]

at 12:05 I dont think enabling OIS with a higher Shutter is a good idea. It will create weird motion blur . better to turned it off when boosting up your shutter speeds

[@MathieuGasquetMirrorLessons]

Well, that's basically what I explain in the video ;-)

[@jayzn1931]

Excellent review!

[@MathieuGasquetMirrorLessons]

Thank you kindly!

[@doptimist]

The 70-300 OIS turns on and off automatically by sensing if it’s on a tripod.

[@albertobeto8120]

Hi! Amazing comparison :) Do you have comments on the image quality regarding the 1.4 and 2x teleconverters? I have the 70-300mm and am interested in taking pictures of the moon, either alone or with some foreground elements. I wonder if cropping the image using the 1.4 TC provides a higher image quality than the 2x? Or does cropping the 300mm image leads descent results? Do you have high resolution comparisons for download? Thanks!! :)

[@MathieuGasquetMirrorLessons]

There is a whole section about the teleconverters in the video.

Looks Good!

From 6:00 it goes way too fast to see what you are comparing to what. We can’t read, listen and compare at the same time. Pausing video every time is also annoying. Please give some introduction what is where in the screen.

The Tamron 18-300 is a better choice than the 70-300.

[@hans-peterkarl5095]

Nice video. But...are there seriously people out there doing Wildlife with a Fuji?? Give me a break. The Fuji XF100-400mm is such an inferior lens optically and from Autofocus, it's simply terrible. Same with the X-T4, this camera is good for resting on the shelves. But not for Wildlife.

[@andyjones6127]

Trolling hard with this comment. Fuji might not be the top choice for wildlife photography but still great performance.

[@rfa2381]

Well maybe the problem is the photographer...
