too slow to focus

I’m super disappointed that the auto focus does not work on the A73 with this adapter (after reading many reviews that it retained full functionality). Doesn’t matter what setting you use, all it does is search back and forth for focus. At least the Canon lens fits, so it got 2 stars.

I used this on a Sony A7II to use my Canon lenses they all worked but each lens had its own focusing issue. My Canon 50MM 1.8 would take forever to lock on. My Canon 24-70 F4 I, it worked best overall. Trying to shoot sports was a nightmare with both my Canon and Sigma 70-200 2.8 lenses as continuous AF would not lock on and center focus worked but even the most in focus images really did not look good. While the adapter works, I would only recommend it for portrait photography.

Achieves quick focus with my Canon 50mm f1.4 and Canon 200mm f1.8

I don't use auto focus much, so I can't really comment on its performance in that respect. What I did notice is that the feature on my Sony that auto-magnifies the image when manually focusing did not work. That said, I was pleased with it in every other respect. It seems to be well made and I am happy with my purchase.

The adapter works fine for aperture control with all the lenses I've tested so far. The autofocus is not good but not a big deal for me since I normally use the camera with manual focus. I recommend it.

I rated 3 stars cuz unlike adapters that are useless, this one can be used ... for some things but not others. If you are expecting enthusiast level high tech magic, you will not find it here. But if all you need is for the auto-iris to operate and the data to record to the exif file, you can use this adapter for MF, and only for FF EF lenses. It will NOT fit Canon EF-S lenses ... altho some non-Canon APSC lenses might fit. If you use EF IS lenses, the IS will not operate ... ever. But the IBIS in the Sony bodies works and the FL data from EF zooms is transmitted to the Sony IBIS system, so that is a very useful convenience. Some EF lenses, Canon and non-Canon, demonstrate varying degrees of AF ... from slow to nothing at all. But for $100 you do get to use your EF lenses for many purposes. The removable tripod interface is very useful. The EF lens latch has minimal play, and the rear flange fits and latches well into the Sony bodies.The front flange has real leaf springs ... this is waaaaay superior to simple slotted bayonet lobes forced to serve as [very inferior] springs.

I purchased this after replacing my Canon T3i with a Sony A7rii. I was not terribly invested in Cannon glass so I didn't want to drop all the money on a metabones but still wanted the option to use my Canon lenses. It doesn't really work like I wanted it to based on reviews I have seen from others, video reviews on youtube, etc. I intend to contact about returning this item as I feel my money would be better spent on something different and I'm not satisfied enough with my purchase to keep it.

I tried using autofocus, didn’t work well with my canon lens. Sometimes it’d snap into focus quick but 80% of the time it was just lost trying to find a focusing point.

Bought this to connect my EF 24-105 L to a new A7Sii. Issues were immediate and frequent. While I was able to take some still photos with it — often after reseating the lens several times and/or turning the camera off and on — it would not work in video mode. I tried AF and MF, manual exposure. With the lens appearing to be functioning, pressing the video button on the side of the camera caused the camera to freeze and no video would be taken. Reseating the lens, the adapter and turning the camera off/on repeatedly eventually resulted in the camera locking up and displaying nothing on the rear screen or in the EVF. I use a Metabones dumb adapter to connect my Leica R lenses to the A7Sii with no problems. Having used that, NIkon-MFT, Canon-MFT and the Metabones Speedboosters, I'm pretty sure I'm not attaching anything or setting anything incorrectly. Bottom line: This adapter did not work for me. My primary video camera is a Blackmagic Ursa Mini, on which I use the Leica Rs with dumb adapters and the 24-105. The A7Sii is new -- a few months old -- so maybe there's a firmware change that Fotodiox needs to make? Don't know. I'm switching to the Metabones adapter. The folks at Adorama were great in facilitating the return -- thanks!!

I had to get a refund and my lens would lose connection to the camera.

The adapter works with 2 out of 3 of my old Canon EF lenses. The third is a 24-60 with a USM that has to be used in the manual focus mode. Not terrible, but a bit of a bummer for shooting ski racing and cyclocross. The AF works great with the other two lenses.

Solid build quality, no problem securing or attaching. But there is quite often a lag between when the lens is attached and when the EVF will recognize the lens. So the screen is black sometimes indefinitely when I attach the lens. Yes, I take the lens cover off! I found the solution is to release and re-seat the lens and everything suddenly works! Not a big deal, but having to do this every single time you mount or turn on the camera is a pain and will add more wear to the adapter. Maybe it's a firmware issue, I'll have to look into it.

This adapter is a life safer . i can use all my canon lenses on my sony A6300 which i also bought at Adorama . And they have an excellent service. They make the difference, ADORAMA !

All functions work .but AF to slow best to use in manual.

I haven't used the adapter extensively yet, but so far it is functional. It is, of course very handy to be able to use Canon lenses on a Sony. There is a bit of fussing involved - sometimes almost seems like superstitious behavior. If the lens stops focusing....turn camera off then on again....or disconnect and reconnect adapter with lens mounted. Means sometimes missing a shot. I have also tried a Neweer. The Neweer is also well built but much lighter and seems to malfunction less often.

I bought this adapter as I have my Sigma 35mm f1.4 lens for Canon and wanted to take advantage of good glass. Unfortunately, Fotodiox adapter did not focus at all (not even once) with this particular lens. Now, I am sure it works with Canon native lenses as I see a lot of reviews by others. For me, I am returning the adapter because it does not work with the only EF lens I kept when I sold my 5D Mark III...

It works pretty well, every once in a while it might lose connection. I generally turn off the camera and take off the lens and put it back on but making sure I put on the lens as tightly as possible and seems to work then. I've had the adapter for a short time so not sure on build quality for long term use. I also have the Metabones adapters and reliabilty seems to be similiar.
