I've been using M5 for a while and really like the size/performance, but always hankered after a full frame camera, so was dissapointed the Eos R is so expensive and limited (no proper 4k etc), so this looked a good alternative, to use my M5 with EF lenses and get full frame performance.Initial impressions were good, and definitely the 1.1 crop is much nicer than normal 1.6, but a couple of niggles, I understand adapter drains battery even if camera is switched off, so has to be removed when not in use, more annoying is that the adaptor stops focus retract when camera is powered off, so 50mm F1.8 STM which is a very common lens becomes very annoying to use,

I have a Olympus OMD EM10 III and also an old 35mm Canon camera.I forked out a substantial amount on lenses in the 2002 just to be overtaken by the digital revolution on cameras.Now finally I bought a lens adaptor to try and use my Canon lenses.It was important for me to be able to have auto focus and that the camera works with the lens without any major issues.It works for my EF 28-135mm just fine and even the EF 28-105 works despite not being on the list of supported lenses.I ran some test for clarity and as an amateur I can not spot any lens issues on the pictures.Yes auto-focus is sometimes a bit slow but again I did not expect the same performance as with Olympus lenses.I am very happy

Works from a single moment you plug your lens inn! my F.4 became F2.8 that just changes the game and I in love with my 24-105 once again. Sadly on M4/3, it became 34-115. But I don't mind for super-wide shots you still are forced to buy M4/3 14MM lens as to get L series 14mm we talking about fish eye 8mm lens which is pricey. Definitely do not recommend to by metabones as back in 2018 metabones most expensive speed booster was 300-400£ when today its 400-800£ just because of GH5 and Black Magic Pocket cameras. Which means they are trying to pull of from people double the price. When Viltrox came in and showed the real cost of a speedbooster I would easy pay 200£ for it as It even feels like that.

What a great piece of kit, if like us you don’t or can’t warrant the Canon Price then this won’t disappoint.... No need for any technical review as nothing technical about it, fit to camera then fit EF or EFS lenses ideally canon as third party lenses can cause issues!And of you go take shots till your hearts content.... nothing more nothing less. ( yes AF is slow, but that’s no different then Canons own adapter, it really comes down to the lens....But hey that’s what manual focus is for).

It does work and I like the fact that you have a tripod mount that keep things nicely balanced on a tripod. I am using Canon EF(S) lenses on Fuji x-e3. When you get focus it is quick and precise but I have found that focussing can be problematic with close subjects, worse with some lenses than others and tricky in low light. For me it's a good stop-gap until I get more x series lenses - a pretty good product over all.

I bought this product thinking it was the speed booster version, unfortunately it's not so I sent it straight back for a refund and bought the speed booster version.So I cannot review this product fully although I will say it looked and felt sturdy although I never fitted it to my camera as I knew it wasnt the version i wanted.Amazon took the return no problem and refunded in full.

I bought this adaptor so I could use Canon EF lenses on my Canon M50, without having a large crop factor. This adaptor reduces the 1.6 crop factor, associated with mirrorless cameras, by 0.71, bringing a Nifty Fifty, down to 56.8mm, from 80mm. Much nearer to the full frame equivalent. I recommend this adaptor for anyone with an M50, who wants to use EF lenses, with a minimal crop.

This works better than I thought it would.I have some Canon EF lenses from about 20 years ago knocking around and they all work fine on my XT2 and X Pro2.The adaptor works so well in fact, that I think I will get more Canon EF glass like the 24mm 1.4 to use with the adaptor. There are also more long telephoto options with Canon, Tamron and Sigma too by using this adaptor.

The product is great and it works perfectly. It's quite nice to get back the field of view lost by the APS-C sensor. Truth to be told though, the gain in aperture was difficult to notice, so in this regard, don't be fulled believing that the out of focus areas will look like full-frame cameras because my experience says it won't

The same results as using a Metabones adapter. It doesn't work with all lenses - my Tamron lenses, for instance don't work with it at all, but all my Canon lenses do. The extra stop that you get really helps in low light conditions. Excellent value for money

What an amazing piece of kit. Means that I can use a whole bunch of different lenses on my Canon M50. One of the most interesting things is that it virtually increases the sensor size and reduces the f-stop. Well-made, works just as it should. Genius!

I bought this to use it with my BMPCC 4K and canon lenses.It gives me an extra stop of aperture, my 2.8 lenses turns 2.0 which is fantastic.Autofocus doesnt work in BMPCC 4K but hey its BMPCC fault haha.love this one.

I use this with my Canon M6, and it performs brilliantly. I have used this with for example a Canon 100-400mmL as shown on the pictures, and autofocus and exposure works perfectly. Warmly recommended.

I have a bunch of EF lenses working hard on my canon M50 and I love it. You feel like it's Christmas every time you see you got a better F stop when you put a new lens on. It's just great.

Does what it says on the tin.I've used Canon's official adapter before and this is just as sturdy. No defects or flaws whatsoever, fits snuggly without any wobble.
