Speed Booster or Adapter for your Canon M50?

[@baldeagle242]

I love my speed booster. You can also remove the EFS adapter from some of the EFS lenses, and they will work with the speed booster also. I actually cut the plastic EFS mount off of my EFS 10-18mm lens so I could use it with the speed booster on my Canon M6-II and it works GREAT for video when I need a wide angle.

[@musicaBG]

Do you have a tutorial how you did it? I'm interested.

[@RVKevin]

Mark, describing the difference in such a way that it is easier for a beginner to understand, i appreciate. I own the Adapter but now i will get the speed booster because now i understand the options it will provide me. Thank you for what you are doing, and the link.

[@markwiemels]

So good to hear! Thanks for the feedback!

[@ThoriumHeavyIndustries]

The easy answer is get both. You need both. And while you are on it also buy a tele-converter. (However it might be a bit complicated to get a Metabones EF-M / EF speedbooster ... since they ship from HongKong) and no shop has them on the shelf. Some has the viltrox... but that´s comes with visibly inferior image quality in regards of sharpness.

[@alexev]

I’m watching your videos and despite English isn’t my main language, your explanations are so clear, that i sometimes understand the theme better with your videos than with videos on my native language. Great work!

[@markwiemels]

That's great! Thank you so much for sharing!

[@Designsforpurpose]

And I almost sold my adapter since I had the speed booster. Now I’m keeping them both. Thank you for sharing

[@markwiemels]

Yes, once I got the speed booster that’s one thing that jumped out at me, all these lenses are now two lenses. Glad it was helpful, happy shooting.

[@tompurvis1261]

I have both. Just got the speed booster yesterday. I tested last night the lower f stop, with interesting results. Canon 80 1.8 now a 1.2. 50 1.4, still a 1.4. 17-40 4.0l, now 2.8. Same for 24-105. I will update the firmware tonight and see if it changes.

[@markwiemels]

Yes, those reading are correct, it's trying to give you the "effective" aperture. .

[@tompurvis1261]

@ I picked up an EF mount Rokinon 85 1.4 today, used, for $130. I would love for it to have an effective of 1.0.

[@joakimskurk]

@@wandersonxavier829 I do mostly photography, and when I'm using the Speed Booster I only use vintage lenses without any AF.

[@hanniosman1839]

Good summary, I started with the adapter and have since bought the speed booster. I tend to have my nifty50 on the speed booster for the wider angle and bokeh effect, then the adapter on my zoom lens. Great combo I reckon, although my speed booster seems to be missing it's software... Still works and I normally manually focus anyhow. Im on the old m3 but still takes fantastic shots.

[@jaimetan]

I love my M50ii! But after watching countless videos of creators jumping ship to Sony, part of me wonders whether or not it’s worthwhile sticking around to see what’s up with the EF or EF-M series… would love your point-of-view in any upcoming videos!

[@markwiemels]

That's a good idea for an up coming video, I will add it to the list. Out of curiosity, what is the Canon M50 not doing, that you think you are missing?

[@benjaminbong]

@@markwiemels I love my m6 mark ii, but I'm really missing a fast super wide angle auto focus lens for it. There's the Samyang 12mm f2, but the auto focus version for ef-m doesn't exist.

[@jaimetan]

@@markwiemels It’s doing a great job for what I need but any time I think of upgrading beyond the kit lens, there are so many opinions about “don’t invest in EF or EF-M lenses coz Canon hasn’t” so then I’m stuck wondering what to do. Mainly my issues are: 1. Longer than 30-minute record time in one go (I use a decoupler when I’m home but not if shooting yoga/meditation videos outside). 2. Image stabilisation that doesn’t crop in so much when turned on (eg. Vlog type shots) 3. A faster, wider lens with autofocus (I just don’t use it at all at night and would love to!) Thanks Mark!

[@stathorinoakenshield6331]

@@jaimetan Vlogging with the m50 in 1080p with digital IS on (not enhanced) is doable especially if you have a lens with is. if you want more than that you have to upgrade. The speedbooster with an EF 35mm F2 IS will also perform good in low light scenarios and you have the image stabilisation in the lens that helps a lot for shaky footage. Best all around upgrade that you can easily resell if you want later is a used Canon 24-105 F4 L IS with the viltrox speedbooster. You will have great quality for photos and videos (unmatched at this price at least for photos) as it offers great is and optics. Also the lens would be at a constant F2.8 at all focal lengths (a bit heavy and bulkier set up though)

[@jaimetan]

@@stathorinoakenshield6331 thanks so much for your considered reply! I’ll definitely look into these suggestions… but like I mentioned - with all the shiny new features Sony includes in their cameras that so many KZbinrs are now embracing, part of me wonders whether I still want to consider investing in Canon… 😅

[@deltacx1059]

0:23 I mean most of these optics have too many elements anyway so adding a extra element that is good quality isn't going to hurt.

I have both Viltrox adapter and speedbooster. I got a M6 mark II. Now that everyone is buying the RF lenses, I am still using EF, EF-S and EF-M lenses that I already have.

I got a Canon A-1 with 4 lenses and Rebel EOS T2 with one lens in a lot of cameras I won in a silent auction a couple of years ago. Decided to try out the 5 lenses.

[@faspete2nd]

I flipped back and forth on my opinion. I had the booster and then sold it. Then bought it again because I missed the versatility of it. Then sold my M50 with the booster. My final opinion was I liked having it. I would not hesitate to recommend it to anyone that's looking for versatility with the lenses that they have. It's another tool to add to your kit.

[@markwiemels]

Yeah, that's kinda where I am at too. Not perfect for everything, but well worth having.

[@MadMusic26]

Thank you for this explanation ❤ I used a 50mm lens with the adapter on my Canon M50 Mark II last night for some astrophotography and was so confused as to why the image appeared so zoomed in / cropped. I think I understand why now after watching your video. So thank you!

[@DanaPushie]

Hi Mark, I had to revisit this video, after some time, as I was unsure of which way to go the first time around. Having taken the time to review the options, and rethink about what I was looking for, it's the adapter I want, not the speed booster. I am not looking to change my M50 ii anytime soon but wanted to consider the EF & EF-S lenses for their quality. Too bad Canon abandioned us M series owners. Lesson learned Canon. I'll be buying used. Thanks for your info and clear presentation.

[@normanfranke4041]

Great summary (as usual)! I have both for very specific reasons. I have the straight adapter for use on my EF-S 55-250 which gives longer reach than the native M lens in that category at a lower price point, and also for my Sigma 17-50mm fixed f/2.8 zoom which is a lovely (albeit bulkier) replacement for the kit lens and great in low light. But I have the Speed Booster for use with my vintage Helios M44-2 EF mount adapted lens for exactly the reasons you described - namely, the intended wider field of view and the artistic effect of the classic “swirly Bokeh” with that lens.

[@markwiemels]

I have tried the speed booster with the Hellios, It makes a pretty wild image!

[@mylifepart2]

thank you - i have a Blackmagic with 25mm lens but the crop factor is too much...i would like a Wider field of view ...hope the booster will help me - nice video thanks for making it...

[@davidtrachtenberg7095]

Most of my lenses are EFS or M lenses. My only EF lens is the 50mm 1.8. No need for the speed booster for the 50mm lens, since I have a Sigma 30mm 1.4. So…I just use the Viltrox non-speed booster adaptor.

[@markwiemels]

Yes, thats a good lens set.

[@Domin0ss]

Nope. The f-stop doesnt change the aperture so speedbooser doesnt affect the dof by itself. It does that because it changes fov and the distance from the subject changes. Dof is not shallower compared to ff but you get more light.

[@lugaroz]

I was just thinking about this I don't have any EF or EFS lenses but I may eventually move to a full frame camera and would invest in those lenses. I plan on sticking with Canon. I have a friend that is a professional and has lots of Canon lenses I could borrow so I may get both starting with the regular.

[@markwiemels]

Yes, if you plan to move up to a RF camera at some point, the EF lenses make a lot of sense,

[@chingymofo1]

I have both. I love the fact that it’s almost like having 2 focal lengths in one lens. I want an almost actual 50mm? Speed booster. I want 85mm? Adapter. Also I’ll definitely buy a couple more ef lenses to really utilise this method and since I’m still a beginner it’s a good hands on and cheap way to figure out what focal lengths are good for certain situations so whenever I upgrade to full frame I know what good lenses I’d wanna fork the money out for!

[@markwiemels]

Good thinking! It is nice that you can take the EF lenses up, and use them on the RF mount in the future.

[@MrLittlecat123]

[@thelowprofile9767]

So why is that lens or adapter very dirty? See at 1:48.

[@markwiemels]

That’s the wear on the plastic mount of the kit lens, they all end up like that with use. Thats why a metal mount is better, the plastic will wear done over time. No lens adapter in that shot.

[@Callomir]

Hi Mark - so would the booster essentially turn a EF-M 11-22mm into a (rounded up) 8-16mm lens, with the bonus of having it a few f-stops lower increasing the overall aperture? I like the idea of just having to buy the booster without buying such an expensive lens for the same result, as a wide aperture, zoomable lens with a decent range is very pricey. So I wouldn't mind a small degrade in quality if it meant I can achieve a slightly wider FOV as well as having a few f-stops lower.

[@markwiemels]

The speed booster adapts EF lenses to work on EF-M cameras, so doesn’t work on EF-M 11-22mm, but other than that yes, wider field of view and larger aperture (more light).

[@josemg8556]

Just the information I'm looking for. Thanks

[@markwiemels]

[@Duke49th]

Why would I do buy a speed booster? Because of the crop factor. Easy to answer. IF I want to use a 11 to lets say 24 mm prime lens, I have no other option. Sadly. Especially not with a good f-stop and auto focus. I wish there would be lenses that have ultra wide angles to counter the crop factor. But there aren't.

Hello 👋 ! So I have a m50 ii , I was thinking to buy a tamron 24-70 f2.8 g2 , the question its what you recommend : speed booster or adapter ? Thank you 🙏

[@barbaranostrand4214]

A lot of lenses are sharper in the center than in the periphery. An adapter will crop off the periphery effectively giving you a sharper image than on a full frame camera. An ideal adapter which introduces no distortion will preserve the peripheral distortion of the full frame lens. Real life lenses will of course introduce transmission effects.

[@markwiemels]

Adapters don't modify the image all all. The smaller sensor just sees less of the image (a crop form the middle).

My guess is, that if you achieve the same reproduction size on the sensor, the bokeh wont be different, but the sharpness would be better without the speed booster.

I think the physics are that with the speed booster you can get closer to the subject, because of the wider field of view, and this is what gives you more blur… I think..

Bought the Viltrox Speed Booster M2 off your affiliate link ;). Question though: Using it with a Canon 50mm f/1.8 on the Canon M50, does it: Make my focal length effectively 35mm like a preferred street photography lens like on a fujifilm x100V? How does this work in regards to the crop sensor? Essentially we are given a non cropped image from the Canon 50mm, i.e. a full frame image? I'm getting confused with the 35mm image/focal length vs the full frame non-cropped image. Is going from 50mm to 35mm achieving the wider field of view, giving us a NON-cropped image, however this image is squeezed onto our aps crop sensor.

[@drunkntigr]

To better reword this: Using viltrox speedbooster on a 50mm on the Canon M50, are we getting a non cropped 50mm full frame image, or are we getting a 35mm image on a cropped sensor - or are these two essentially the same thing?

[@wubbadubnub]

@@drunkntigr Essentually it is the same thing, the focal length is basically the same (however, on a 50mm on a cropped sensor, it becomes more like a 56mm uncropped since it is 50mm x 1.6 (crop factor) x .71(speedbooster) and this applies to all lenses). Hope this makes sense.

[@GrantMcWilliams]

After buying virtually every EF-M lens focal length available and taking them traveling with me I've decided I just need a 15-45 mm (24-70 FF equiv) but fast. The kit lens is not fast enough. My 22mm pancake is nice but not wide enough on my M6 II. Now I'm looking at EF lenses and using the speedbooster to try to get me into the focal length that I need. The problem is lenses with that range that are fast are already very large and heavy and then adding the speedbooster makes them uncomfortable. Oh, how I wish Canon's 24mm was an EF and not an EF-S lens. Anyone have any suggestions on a 24-70mm FF equiv fast lens for EF-M either using an adapter or speedbooster? I find myself leaving my 22mm f/2, 32mm F/1.4 and 56mm f/1.4 in the hotel when traveling. There are wider zooms but slooowww. There are wide fast primes but they're primes.

[@markwiemels]

I have had the same experience, have not really done the research, but I can empathise with your position. I see people talk about the Tokina 11-16 f2.8 as an option, seems to have a cult following. Seems like an off focal range to me. The issues with fast zoom is going to be the size. There are rumours of Sigma offering an APS-C 18-50 F2.8, which would be prefect.

[@GrantMcWilliams]

@@markwiemels When I started taking photos again I really didn't know what focal range I'd need but now it's very clear. I need to get far enough away from buildings which at 22 I can't. I have the 15-45mm EF-M, the 18-55 EF-M and the 18-150mm EF-M lenses. I use the 18-150 mostly. It's faster than the 15-45 and covers a lot of focal length. Still not ideal though. Before Canon decided to abandon EF-M it was rumored that they were going to make a 15mm f/2, 18-45mm f/2.8-4, 52mm f/2, 62mm macro f/4, 100-300mm f/5.6-8. At the time I would have bought four of them. Now I have the Sigma 56mm but I'd still buy 3 of those lenses if they released them. The 18-45 isn't as fast as I'd want but is quicker than the kit lenses. The 15mm f/2 would undoubtedly be smaller than Sigma's 15mm f/1.4 so I'd buy that too.

I have the speed booster & it’s def harder to focus and needs to be on a tripod almost all the time cause any movement even the tiniest will make the image blurry, if anybody has any suggestions I’m open to trying some out

[@markwiemels]

This is likely just the shallow area that becomes in focus with the speed booster. From a movement perspective, looking at camera shake, the speed booster allows you to achieve higher shutter speeds, so should be even less prone to camera movement than the adapter.

[@tango3004]

I have a M50 mark II. I recently purchased a speed booster. However, when I use it with a Tokina 11-16mm lens I get vignetting on 11-13mm focal lengths. Is this normal or a defect? Do I need to change a setting to remove the vignetting?

[@markwiemels]

That’s an APS-C lens, the speed booster takes a full frame image and squeezes it onto the smaller sensor. So essentially that lens and the speed booster are not meant to go together, so yes, what you are seeing is normal.

Question for you. I have a M50 and a collection of 5 EF-M glass. I'm just a photographer with no EF lens. Do you think its worth it to start investing in a speed booster, Adapter and EF glass or in the long run just better to go with a RF second camera like RP and/or R7? PS I do want a second camera. The question is over the value of delaying getting a second camera.

[@markwiemels]

The EF lenses do allow you to use them with RF cameras, and they are more affordable than RF lenses. RP is a lot of camera for the money, I’m a big fan.

[@okaro6595]

Buy lenses for a need not as an investment. If you need a new lens you might consider adapting EF lenses for future compatibility. Of you go to EOS R later then you likely want to buy RF lenses so the EF lenses would be a compromise.

Great video Sir! Just bought a viltrox adpter for my canon m50 mark2, can i use my friend nikon d90 kit lens using this adapter? Thank u very much!

[@SchardtCinematic]

Do they make a speed booster for the Canon EOS R7 and R10?

[@awesomecatvideos4723]

I'm definitely a speed booster kind of guy. I love the video quality

[@markwiemels]

yes, it's a pretty cool look.

[@Navyman2004]

I have an EF 75-300mm with Viltrox speed booster should I invest in the EF-M 55-200mm... Thoughts?

[@markwiemels]

Only if you need the image stabilisation.

[@DrJon-zf2xo]

I beleive you are wrong about speed boosters always reducing resolution. The speed booster does need to consider the lens design. A well corrected lens is going to send the light to the sensors in cones with points st the sensor. The speed booster only needs to increase that angle and it is the same range over then entire frame, regardless of the lens focal length or aperture. If the original lens has aberrations the speed booster may make it worse but I have used speed boosters on my Nikkor 180mm f/2.8 AI and it still out resolves my APS sensor. My experiencxe is that these work very well on very good, sharp lenses at full aperture..

[@rubabmubarrat]

just buy both. I got my adapter today. Later I will buy speedboster

[@psallen5099]

Does using the adapter create a zoom effect with an EF lens? If so how much?

[@markwiemels]

no

Will the Viltrox Speed Booster work for the Canon M50 with a Laowa 9mm f/2.8 manual focus lens for Canon ef-m mount? I'm trying to get more light in and wider 4k shooting real estate. Thx!

I recently read a comment (not on yours) that the Viltrox adaptor has a shiny black surface on the inside which bounces stray light on the sensor. I have and use both the VILTROX adaptor and booster and the interiors of both are matt and I've never experienced the light flash he described have you?

[@markwiemels]

I have had this reflection issue with the genuine canon adapter, but not that Viltrox.

Just got the sigma 18-35 and gonna get the adaptor for now. Great vid man tho

Probably the EF 100mm, but it can be a bit pricey.

@@daniellc1331 ok, yes, don’t use the speed booster for macro, it degrades the image and detail.

wait! I can still use ef-m to ef-m+efs lenses? Am I getting that correct? or do I need to buy multiple? help.

Is this lense compatible Canon RF 35mm f/1.8 IS Macro STM For canon m50 mark ii, if you have an adapter?

Hello, i have a m50, and i'm planning to buy the 55-250 or 18-135 EF-S lense, should i buy the speed booster or adapter?

[@markwiemels]

adapter, they wont work properly with the speed booster.

Which one do you recommend for m50mii with a macro lens for dental photography purpose?

[@ronreaper3739]

Lens: Canon EF 17-40 F4 L Camera: Canon 5D mk ii & Sony A7ii Adpater: Viltrox EF Nex IV If i use canon FF sensor lens on canon FF camera and i shot on 17mm fl, the image output will be exactly 17mm wide. When i use canon ff lens on sony ff camera body with the adapter & i do the same shooting on 17mm, would i get same result? I mean i get exactly 17mm wide image, or it will be different like wider or narrower image because there's something called mount conversion factor? I ask this because im new to this adapter, and i want my canon lens work exactly like on my canon ff body.

[@markwiemels]

You should get the same, or almost the same (maybe the slightest variation), field of view.

[@ronreaper3739]

@@markwiemels what will happen if i use FF sensor Lens on FF camera body with this speedbooster?

[@markwiemels]

@@ronreaper3739will likely get a bad vignette.

[@ronreaper3739]

@@markwiemels i see, so the conclusion is if you want experiencing ff output on aps-c camera best option is speedbooster because it magnify image near ff size image. Other than that just pick adapter.

[@krishnasr597]

Hi, for canon m50 mark2, which is best buying efm lenses with high price or buying ef lenses with adapter in budget ?

[@markwiemels]

It really depends on the lens, but I wouldn’t hesitate to buy more affordable EF lenses and use the adapter, you will get great results.
