Fotodiox PRO Lens Mount Adapter - Compatible with Canon FD & FL 35mm SLR Lenses to Canon EOS (EF, EF-S) Mount D/SLR Cameras

In short, This did exactly what I wanted it to. it allows me the use of my old FD mount lenses on a EOS/EFS body, and does an extremely good job at it. construction of it is solid no looseness at all. have had no problem mounting any lens to it. I would buy again and have already recommended it to my friends with the same interest.In more detail, This adaptor does exactly what it said it would. the instructions were very clear. and packed very nicely. it's compact enough to take next to no room in any camera bag. and the thing I was most concerned about, I've read advisories about these adapters (Not this brand but as a whole) blocking the mirror from flipping properly from being too close into the body. This one did not have that problem at all. Another concern was it's ability to support weight. the old FD lenses were not lite being made of glass and metal, but this has been no problem at all I've had a telephoto hooked up to it without any concern of it falling off or worse yet damaging the mount's on the camera body. as I said at the start the adapter is made very well. of nice metal and glass there is nothing on it at all that would make me feel like it was cheap. If I could change one thing it would be the color. the bright blue ring stands out like a sore thumb. but hey you're taking pictures of other things so in the long run it does not matter how it looks doing it.As you could imagine using a FD lens you'll lose all your snazzy features that the lenses of today offer you. there is no image stabilizer so for someone like me that's a little of a set back I can tend to bump the camera at times so a tripod is almost a must, there is no autofocus it's all done by manual (I mainly shoot with MF at any rate though) aperture is semi manual. you do have the ability to set the light sensitivity of your camera and than adjust the lens aperture but that leads into a trick I'll detail in a second, as a whole this is a amazing adapter that I wont be without from now on. it allows me to use all the lenses my grandfather's and uncle gave me rather letting them just become forgotten about.Depending on how your lenses were taken care of they might need to be taken in for cleaning. the ones I have gotten were always kept in a thermal camera bag and never bothered so they're great. but a lot of them have dust even meldo in them. don't let this put you off. they can be cleaned and brought back to their youth by a professional and still more cost effective than buying that lens new. different lenses are different quality. I've had amazing luck with my 70-200, 35-105, and 100 macro, but had a little bit of a love loss with a 50MM prime. it just was not as clear as I wanted it, this is in no way due to the adaptor however it's a factor of the lens itself. but the reason I brought it up is to say one lens may look bad but don't knock this adapter for that, try again and see if you can get better results.That pretty much wraps up my review of this adapter I'll now go over the trick, I found that adjusting the "Install" ring can allow you to manually over ride the aperture of the lens. I found often times when the picture was just too dark and turning your shutter time to 30 seconds didn't do much either. that turning the ring back towards the install mark would allow the image to brighten up substantially, being that the ring is free turning there are no clicks it's a great way to get that perfect brightness just like using a dimmer knob. when I get the chance I'll be uploading pictures I've taken with this and the lens used. hope I was able to answer some questions and should you have any further questions or just want to discuss it over all before buying feel free to let me know I'll be more than happy to go over it with you.

Ok, so I bought one of these. I wanted to use it with an old 50mm Canon FL lens from 1967 that I inherited and was used to take most of my childhood photos. I have a Canon T7i, a nice, modern ASP-C sensor DSLR. Would it work? The short answer is yes, it does, and fairly well. Once I got it on and played with my camera, I was taking decent photos within an hour and they had that vintage vibe these old lenses can provide. I'm very pleased with it.Now the caveats. As noted by others, it was tricky to get the lens mounted on this adapter. It actually took a little force to snap it down into place before tightening the bezel ring. I needed to press down harder than I expected. Once mounted, I needed to put both the lens and the camera in manual mode.In the case of my 50mm, on the crop sensor, it is equivalent to a 75mm lens....not great for much, as you need to step way back to get a person or object in frame. I also needed to set the shutter speed and ISO on the camera for lower light conditions. I could then use the manual aperture adjustment on the lens to get the light right. Without doing this, it is very hard to achieve a sharp focus.That said, even with ideal settings, this lens produced very soft images and was not as sharp as a modern Canon lens. In looking back at the old film photos from the 60s and 70s that were shot with this lens, I find that they are also fairly soft and vintage looking. As such, I think the lens is behaving true to form and the adapter is working well.Will I use this lens/adapter combination regularly? Definitely not. It's now at best an art lens for special circumstances and is inferior optically in my estimation, to even a low-end a modern lens. However, I can see using this adapter with some of the better and more modern FD lenses from the 70s and 80s.In short, the adapter does what it's supposed to do and does it well. I find its build quality to be good and I will definitely use it with other FL and FD lenses if I have occasion. However, the fact remains that these old FL and FD lenses are, for the most part, not as good as modern lenses and/or not optimized to work with modern DSLR cameras. This adapter will not turn your old film lenses into modern, high performing DSLR lenses, but it will let you use them for nostalgia purposes, retaining their original character, blemishes and all.
