I'm confused and shocked that the Metabones lost the nice swirley bokeh that the generic maintained in the last comparison. That alone would rule out the Metabones for vintage lenses.

I expected the generic to do better. It was easy to tell which was the generic in every test. However, it was hard to tell the Viltrox and Metabones apart. I would have liked to see tests of chromatic aberrations in high contrast areas like tree branches against a bright sky to see if the Tantalum glass in then Metabones provides better aberration control than the cheaper glass in the Viltrox.

Very surprised with the results! Sometimes I could guess but in some cases the generic looked the best, in my opinion. You are improving the quality of your channel very fast. Hope you continue grinding up and doing more and more videos. Thanks for all.

that was one of the best comparison videos I've ever seen lol no joke. That was cool. im getting viltrox. I thought they were the worst on the first guessing video, but it was my favorite the rest of the way. thanks for the vid!

I use the Viltrox for M4/3 and love it.. Really breathed new life into my photography and filmmaking. I use a ton of vintage glass but also some EF lenses. I amazed by the image quality and shallow depth of field speedboosters give, I only wish I had done it sooner. Great video as always!

Another very useful video, thanks.

Thanks for making this awesome video! New to all of this and I have recently acquired a GH5. I just ordered the Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon with the Metabones Canon EF to Micro 4/3 T Speed Booster ULTRA 0.71x. On some other video I saw that if it wasn't 'ULTRA' there would be vignetting. Honestly I think the Viltrox is fantastic and the price is unbelieveable. I'm still waitng for the Metabones coz it's on 'backorder'. So I can return it coz it hasn't got here yet lol But I worry about the vignetting. Not sure which Viltrox would NOT have the vignetting for my setup GH5 and Sigma 18-35

That was such a sweet comparison, Man. Just the vibes of the vid were enough to keep me engaged throughout the vid and the quality of content was top notch. Keep up the good work, Man :)

Don't forget aperture control, besides autofocus and stabilization on modern lenses which can't be used with the generic speed booster. But it looks great with manual lenses!

The comparison at 6:54 is very clear. Metabones has the best color retention, contrast, clarity, and no chromatic aberration to be seen. Go full screen you will see Viltrox has severe chromatic aberration at the corners, and white is turned bluish. Metabones is best overall but also by far the most expensive.

Thanks for making this video! This definitely answered my question. :) Metabones wins, but Viltrox and Metabones look very similar. However, as everyone is saying, the price for Metabones is ridiculous. There's no point getting it when we can just buy the Viltrox for a lower price and save the rest, or spend on another lens, or something.

I would definitely sell the Metabones in this case, even if you could get half your money back. $800 is insane.

Thanks For this sir. Im not gonna go for the metabones anymore haha. From those footage can't tell the difference but yeah there is but just a hair not that much viltrox is great. Thanks Again sir. 😊

Nice to Watch you again 👏

I noticed that the Generic speedbooster produces a softer, less contrasting image and softens the sharpness. This allows you to combine two into one, i.e speedposter and CineBloom filter, recently promoted by Moment. Why buy a sharp speedbooster and a CineBloom filter when you can get things done with Generic? And this is how manual autofocus is usually used.

Kickass review as always, thanks.

What a great video! Thank you so much! It is really great to know that for just getting started that this generic speed booster works great! )))

Great video Zeek. I had the impression that the Viltrox, while supporting AF in video for certain lenses, didn't support AF for all lenses. Can you comment on that or do you think they have corrected for this via recent firmware or whatever. Thanks and great vid!!

Zeek, big salute for the attempts you have been making to promote Magic lantern...... You always found to use the speed booster on eos-m. It has an APS-C sensor which can produce sufficient shallow depth of field. Then is it worth using a speed booster. Please share your views. 🧡🧡🧡🧡🧡

Metabones did seem to be better though...when I could notice. Thanks for putting this together!

I use a lot of manual vintage glass and it looks like the generic does a pretty decent job. That said, the extra versatility of the Viltrox makes it a no-brainer for $150. The Metabones is a ridiculous price and simply isn't worth the money. You're getting marginally better performance in some tests, but in others it's worse than the Viltrox and generic. Anyone who pays $800 for the Metabones needs their head testing. You can buy a couple of decent lenses for that price.

thanks i love you hate how much you have to know to get this right.

This is really helpful. Thanks!

Great video good analysis

Can’t wait to kit out my eos M!!

Besides the flare comparison I consistently preferred the look on the generic speedbooster to the other two, which shocked me. The metabones especially didn't seem worth the price tag.

For value def think generic is way to go. I found it a bit softer wider open than others but i actually prefer a slightly softer look anyway. Actually thought it had most pleasing bokeh and dof separation. Thanks, i was thinking of getting metabones but i don't think it's worth it now

I agree, but the viltrox needs firmware 2.3 for the stabilizer on lenses to work. Any other firmware does not work with this, and their older firmwares are not on their site no more...

Hi Zeek, Great channel by the way. I have a Minolta Rokkor 58mm f/1.4 I would like to use on my Canon EOS-M and M6 with a speedbooster to eliminate the crop factor. I already have the generic adapter Minolta=>EF-M. Is there a speed booster that just works the same? Or do I have to use a Minolta => Canon EF adapter then a EF => EF-M speed booster ?

Just got mine viltrox today thanks for the review it helped a lot. In general It worked pretty good with my 50mm 1.8 ii and gave me more wider look. Only confusing part for me that, I can't get to see my aperture goes lower then f1.8 on my camera screen even after the viltrox firmware update. The odd thing is, I have a regular ef to ef-m glassles adapter too (commulite) so I can compare. After comparison test between regular commulite adapter and viltrox, I realized my viltrox speedboster with same nifty fifty, same iso, and same shutter in 1.8 aperture performs slightly brighter then my regular commulite adaptor. I am confused that people on amazon reviews showing that they were able to see f1.2 on their camera screen with the same nifty fifty and eos m.

The Viltrox does not support IS from Canon IS lenses to the Fuji body - tested 3 different lenses - it shots off after 3 seconds

Your viltrox renders fine at f1.4, mine is crazily soft

Thank you Zeek.

can u do a test on the speed booster at different focus lengths to see if defocused areas shift to cause chromatic aberration on a larger black and white chart?

The best comparison video ever seen i'm with viltrox .Good 👍 job

One thing that will save a lot of Mac owners a big head ache is to not upgrade the firmware on the Viltrox on a Mac, borrow a friend’s PC instead! Be warned!

So because I wanna make films, does the autofocus work better on one or the other and secondly would I get more of the surroundings in frame more with a EF 85mm than a EF-M 85mm from the same distance?

using manual lenses doesnt show the aperture of the lens on the camera itself. but lets say i have a manual lens like f2.8 and using a speedbooster, will it be like an f2? or for like a f4 to be like a f2.8? i know on a viltrox with af lenses it shows the aperture on the camera. im not sure if my vintage lenses might still be at the same aperture after a speedbooster.

I agree, Viltrox wins in performance/price.

Did you notice any colour cast between the three or variance in contrast? I thought I noticed some minor differences.

I feel a little bit swirly bokeh with filtrox speedbooster...

The price of Meta bones, at least where I found it, B&H, is now half the price. Did you mean to stay away from metabones because of that price?

Thanks for helping

What a great video! I have one question have you ever tested the commlite speed booster it's cheaper and have af/is? I cant find any comparison :(

Crazy that you answer all my questions 😂 So that’s great, no need to buy this expensive (overrated?) Metabones !!!

happy with the Viltrox,

After watching other reviews of the Viltrox most said they couldn’t get infinity focus with the Viltrox did you find this as well.

Thanks for this comparison. What i'm really interested in is the power consumption of the metabones. Does it draw more or less then the 10 mW, the Viltrox constantly drains out of the battery (even if the EOS Mx is switched off)?

Hey Zeek, I encountered a firmware upgrade failed try again message whenever I attached a M42 Helios lens with adapter chip(M42-EF) on my EOSM+Viltrox Speedbooster. Could it be the adapter w/ chip?

hello!! I have the eos m and the eos m50 right now... I got the viltrox one just some minutes ago, but it doesn't work as I was thinking with my canon 50mm 1.8 FD, now it works like a macro... however it works very fine with my helios 44 2 58mm. Is that ok? (I saw you video about how to get a macro with the adapter plus the speed booster, so I didnt expect it works like this with mt FD...)

Hey Zeek, I've been looking for a speedbooster for my vintage nikon lenses to the eos m but I can't find one anywhere. I don't see why you wouldn't be able to adapt so is it just sacrilegious? I've got a regular adapter on the way, but I had to ship it from china. What the heck? is there some sort of patent issue? I wouldn't care if I didn't already own nikons.

Hi me i have Adaptateur de Canon EF et EF-S à EOS M - Meike MK-C-AF4 buy on amazon i ll be like to compare this meike to vitrox and metabones is good but i really want knox if metabones or vitrox has more speed for MAP (time to have for have correct focus point)

Big thanks for this video! I like to use MF vintage lenses so the generic option suits me fine. Glad to hear (and see for myself) that there aren't any optical limitations with the generic. I actually went straight for an M42 to EF-M focal reducer (meaning one less adaptor in play). Really helpful video, as ever. Thanks again.

hi Zeek, i am wondering can you get a speed booster for a canon 200d? So basically a EF to EF mount to run a speed booster? Cheers

The generic speedbooster has the lowest contrast and makes bokeh a little less pleasing, but the Viltrox and Metabones are extremely similar. Metabones is insane with their pricing. Fantastic video as always.

Hi Zeek. Ive been watching your channel for a bit now, Im very interested in eosm camera ability to shoot 2.5k RAW, and be my B cam to M50 I own. I have a question about viltrox speedbooster. I have Sigma apsc 17-50mm 2.8 which on speedbooster gives a vignetting on eosm sensor, since ML crops sensor even further this should get rid of vignette and I should get f2, closer to real focal lengh as speedbooster gives 0.71 reductiont? Would that be correct? Cheers.

I notice you have the speedbooster for EF-EOSM but what if you have an EOSM lens and want to speed bost it? Is there EOSM-EOSM speedboosters out there for that purpose?

What about the Canon version?

Thanks again, Zeek. I've ordered the generic 42mm speed booster, I have 2 lenses to use it with. I don't suppose there is a C-Mount booster ?? I haven't found one, yet ??

Would you say that VILTROX EF-EOS M2 0.71x Speed Booster is a good choice? Because I am on a tight budget and I have one 35mm EF mount cine lens for EOS M camera. I am thinking of using a speedbooster to use the cine lens as both wide angle lens and standard wide lens. Therefore, I will have equalient to using two lenses for the same short film.

I like zhongyi lens turbo ii! It's crazy sharp, like a metabones! Try it!

Hello Zeek, I have the EOS M with the Viltrox EF-EOS M2 . If I get a Helios-44M-4 with an adapter, can I use it along the Viltrox? or Should I get a Canon FD 1.4 50mm ? It would be an advantage to use the Viltrox with old lenses right? Thanks

I have purchased the viltrox and used it on a m50 mark 11 with a 3rd party cropped sensor lens and noticed heavy vignette from 14mm to about 20mm in my photos. Does the megabones still have vignette in the photos when used with a 3rd party crop lens? Thanks

B，Viltrox👍🏻

4:30 good one🤣🤣

Hey, I checked this Pixco page, can you clear 1 thing for me? There's said "Pixco for EF", does this mean that I'll need to put EF-EF-M adapter on it in order to use EF-M lenses?

Really love this clean image !!!!! 30mm?! M50

Great video Zeek 👍🏽 I was going to ask, I have 3 lenses I use my eos-M with, the canon 24mm 1.4 ii 50mm 1.4 and 135mm f2 but how do I adjust them at a lower aperture? When I use them they just stay at their original aperture. I believe you can bring in more light into the sensor correct ?

Question I had has been answered in this video

I'm sorry, but it's not a helpful test at all. Why didn't you do a stopped-down test with the field footage? At least the Gorilla (which appears the same as generic) speed booster (Nikon g f lens to Sony e) is just unusable at any f stop other than wide open to f4. From about f5.6 onwards, you get a coloured blob in the middle of the image. The Metabones will boast superior-quality optics. Which is why it's more expensive. I can't vouch for Metabones with Nikon mounts but I can with ef to e and there's absolutely no coloured ghosting and blobs at any f stop. Maybe it's a matter of 'you get what you pay for'?

Thanks for this Great Video... I want to ask a weird question 🤷🏼 Can you Adapt a speed booster on a speed booster example viltrox Ef - rf and rf - ef. Double speed boosting... I'm trying to Turn an S35 Camera into a Full Frame camera using boosters

Before I see the mystery speedbooster reveal. It has pretty bad chromatic aberration with longitudinal aberrations

I also have the EF-S 18-135mm ....I wonder if it can be modded to be used on the EOS-M with the Viltrox booster and if it will vignette, any idea?

Hey there, after your video about making the Canon eos M a budget Bolex 16D I got my self a vintage lens for super 16mm, thanks to the cropfactor the lens it a bit tight so I was thinking to get a speedbooster for it, its a PL mount wich can be adapted to the EF speedbooster but my concern its about quality, you think pairing them up will be a good idea, have you tried it?

i can't see the different of three lenses, how many stop of viltrox ibis can handle? thanks to all zeek

hi zeek quik question do you know the difference between viltrox m1 and viltrox m2 cant find info on Google thx

How do you connect 3 SB's as in your video title photo?

THAT GENERIC ONE IS DEFINITELY THE WINNER.. AND VILTROX IS SECOND...Metabone is not sharp at all

Does viltrox one work with eos m1?

Если покупать метабонс, то только 0.64 версию

Metabones GIVEAWAY 😁😁😁😅.

Viltrox it is.

Who is the model?
