Works perfect for my Canon Rebel T7! I got a FD Canon 30-70mm and it works great, there is no auto focus but the Manual focus is very easy to do! No problems with depth of field looks great and you can’t even tell it’s a separate piece, it was easy to install as well! For some people they had it easier if places on lens and then the body. It worked better for me to place on body and then add the lens! I got some great images on my first 2 tries!

Fit teh lens and camera quite well!

I purchased two of these so i could use T-Mount lenses on my Canon EFS. The finish on these aluminum adapters if very good and the adapters fit the Canon quite well, including the locking pin. The price on these is also very reasonable. I have had some adapters that do not fit this well, but so far the Fotasy products have been very good. I have a similar Fotasy Canon EF-M to T-Mount and is very comparable in quality. The same is true for Fotasy filter ring adapters.

To get the lens to stop down (darken when you move f/stop ring) you must:1. Mount the adapter onto the camera. 2. Slide the ring to OPEN. 3. Mount the lens. 4. Slide the ring to Lock.Some FD lenses have a lock switch on the end that attaches to the camera: just slide the lever towards the lock and switch the tab to 'L' and then you can work the f/stop ring and the blades will close and open-permanent prewpview mode!I successfully used this adapter on a Canon T2i camera to adapt and old Canon FD 50mm 1.8 S.C. lens and also used it with and without a Samigon CF1 Auto Teleplus 3x tele-extender.It's been foggy for days, but I am able to focus on trees in the far-off distance, so I believe this will let you focus to infinity (which is why THIS adapter has a glass lens in it). Photos look sharp edge-to-edge, corners look fine, no vignetting.Adapting a 'free' f/1.8 lens is very nice--lots of light and blurred background--but manually focusing with such shallow nice depth of field takes a little getting used to. At first I thought the lens was a little 'soft', or maybe the 40 year old UV filter was dirty, but maybe it was just a little lack of focus on my part.(update: all the FD adapters have a lens in them which creates haze, NOT in your viewfinder but in the final image at wide open fstops. f/1.8 is like a glamour photo on bright days, very hazy like fogged eyeglasses on a cold day. Stop down and it gets better. This seems to occur no matter what brand adapter used as far as I can tell from my reading online. Lighter objects almost glow with haze. I've adapted Olympus and Nikon lenses just fine but they are just metal adapters: no lens in them. My lens is useless at f1.8 but around f8 it's fine. On video it seemed okay too so I'm still happy, but I'm glad all my other lenses are adapted w/out glass adapters. Old Canon FD lenses just don't adapt as well as other makers-at least at extremely wide apertures. Your old Canon lens might be a telezoom that doesn't even open to 1.8, in which case you might be fine. My 3x tele extender also 3x the f/stop so with it the softness I was seeing was really at f6.4 wide open.)Just in case you didn't know: your autofocus points will NOT light up and beep; you can use a Canon T2i on auto but your aperture will not register so you'll want to use it on Manual and adjust ISO and shutter speed on the camera after setting your f/stop on the lens manually. You will be focusing manually as well.One other thing you might not be used to: old lenses have lots of jagged little levers and posts sticking out of them. Do not let them poke/scratch the center lens in this adapter. It's VERY easy to let this happen.I already had a lens cap for my really old lens. The supplied front cap with this kit fit nicely as a body cap onto the old Canon FTb 35mm film SLR body which I snagged my lens off of-NICE! Now I don't have to buy a body/dust cap for the old film camera body. The rear lens end cap that came with this adapter says Canon on it and fits the adapter nicely.I tried this on 1/7/17 with a Vivitar 28-210mm 1:3.5-5.6 macro focusing zoom lens With c/fd mount. On my eos with this adapter I can NOT focus on the house across the street or to infinity. I can however use the push/pull ring to pull to focus on object in the same room as me up to almost touching the lens, then turn the focus ring on the lens to get nice focus. I took video with this setup of stuff on a coffee table and it was beautiful! The house across the street is just a blur. In the video I was able to adjust f stop blurring and unbluring the background behind object in the coffee table (follow the procedure above for mounting or else for fstop will be locked open). With this lens i get less glare/haze at either end of the fstop range so that was nice for photos. In video i had no glare problems with the vivitar.Each old lens is different with these Canon to eos adapters.I got this last old canon lens for $5 so it's nice to be able too use them as macro lens and sometimes beyond. HOWEVER: the worst lens to adapt to eos are old canon fd lenses. The old olympus zuiko lenses need no glass in their adapters and just pop on and work to infinity. Same with ancient Nikon lenses.If you're planning on buying a bunch of old film lenses for your newer digital canon dslr get olympus and nikon adapters and lenses-those adapters let those lenses work perfectly. All canon to eos adapters do NOT allow old canon lenses to work perfectly, but they can still be fun. I have a 4000mm old olympus lens and can focus on bolts and screws on passing airplanes, canon fd lens adapters won't let me focus on the house across the street.Moreover: canon fd mounts are physically hard to take on and off the original cameras and these adapters. The adapters for old olympus lenses are easy to use. The adapters for old nikon lenses tend to get stuck on the old lenses. I have 1 canon fd to canon eos adapter; I have 1 Olympus om zuiko to eos adapter. I have a few nikon to eos adapters PERMANENTLY STUCK onto some old nikons. Every old nikon someone gives me gets its own adapter since the jam on, lol. It's all great fun.Old nikon: video. Old canon: macro video. Old olympus: great super telephoto, macro, ultrawide, fisheyes, etc.If you have a box of old canon fd lenses then go for this. If you have a resale shop with lots of lenses: buy nikon and olympus adapters and lenses. ALL CANON FD TO EOS ADAPTERS DON'T WORK PERFECTLY (unlike the nikon and Olympus adapters).Nikon and olympus to eos = serious photography and video work can be done.Canon fd to eos adapters = fun, occasionally decent macro, weird effects, better than tossing the lenses in the garbage.-Mike from DetroitMichael Logusz

This adapter is just horrible. While it technically allows you to mount FD lenses on your EF camera and allows infinite focus, the image just looks like bad. You lose some field of view (it magnifies the image slightly), you also lose a stop or two of aperture (dims the image), but worst of all, the image is washed out and there is a very noticeable softness, like using a 1970s soft focus filter. It looks very similar to pictures taken with a cheap point and shoot camera on a hot rainy day (think fogged up lens). I would return this item, but the box it was shipped in got tossed out so I’m stuck with it.I have attached two images the focus was as good as I could get with my usually tack sharp Canon 50mm f1.4.

After trying multiple adapters I finally found one that actually fits my camera. Just for reference I have 2 Minolta MD Rokkor -X lenses one is a 45mm and the other a 50 mm both fit on my Canon EOS rebel T6 with the MD-EF adapter.
