Only reason I use adaptor is for Canon FD 50mm f1.2 on full-frame 5dII. How bad is the image at wide open f1.2?

I do not have the 1.2 I do have a 50mm 1.8 and a 135mm 2.8 and I use this adapter with a T4i and the quality is amazing. The FD lenses were made really well. The only thing with a 1.2 the depth of field is so shallow you are likely going to blur out half of your subject. You may not want to shoot that lens wide open. However if you do I am sure the photos will look amazing. I hope this helps you out.

I have encountered the same problem and almost thought about returning it. Be patient. It seems that you could not mount your fd lens to the adapter. It is easier to mount fd lens onto the adapter before installing fd lens+adapter to your camera body. There is not mark or dot to line up, so you have to use your eyes. Visually line up the flange of the adapter (on the side with a screw) to flange rail of fd rail. Ensure adapter's flange goes underneath fd lens's flange rail, so a lens can be held firmly onto the adapter. Then turn the adapter clockwise to lock. Good luck.

It can be used with 35mm f1.8 as long as it is stepped down to greater than f4.0. The image quality is not as sharp as without the adaptor but it is totally usable.

Many thanks for replying. Have just ordered an adapter ( cheaply), as I only wanted the lens to play around with. Lesson learnt ; Hubby cannot buy lenses without me knowing what he's paying out for !!

I have used this adapter on a 60D and a rebel with excellent results. Many of the prime FD lenses produce beautiful pictures although they are all manual.

Beware of the Neewer brand,Gnarly*. I got one for my a7r and caused some bad flare on the image...you might be better off getting the Fotga brand, 4 of the adapter I got works w/o issue.

The short answer is no it won't have a black circle. However, are you using this on an A7(n)? If so, I'm not sure if there will be any vignetting from the adapter itself (your full frame lens will not be an issue). But it is important to note that you super nice lens will become manual focus, no IS, and stuck at a wide open f/2.8... This is all fine if you just want to play once in a while, but you'll eventually want to have a lens that can at the very least stop down.

The adapter does allow you to use the full function of the Canon lenses. The mount was some what loose and could possibly loose contact with the pins. This is annoying and was the reason I returned the item. I heard that some people received a better fitting adapter that did not have the play I experienced. The Canon version does not have this issue. Quite a price difference but I really like the Canon one better because of the fit issue.

Certainly not for me, I could not justify the reduced light transmission of the APD filter. I use this often at f/1.2 and the APD version may be worse than f/1.4, some say 3/4 an f stop. Personally I thought about changing until I saw the impact on light and a rendering that i did not prefer.

It is not a debate. The sensor in the full frame is larger, therefore more pixels, more info, better image quality. When you look through the viewfinder in the full frame you get 50mm, it's not expanded. Either way this is a good lens. You have to know how to use it is all.

I'm not sure if the lens will work without an adapter sold by Opteka. I would caution you about this lens in that it is difficult to focus and get your exposures correct. Also the lens is not suitable for any subjects that are in motion as the aperture settings are slow and require long exposures. Hope this was helpful.

Ditto on the other answers, plus I added a Wide Angle Converter Lens. Expensive, but worth the price to avoid panning.

at f2.8 it will be tough, since the DOF is pretty shallow, but you don't want to shoot portraits that wide open as they tend to be soft wide open on most lenses. if you want nice bokeh just increase the distance of your background behind your subject, while closing down the lens a few stops. but this lens should take sharp photos.

You don't. You buy an ND filter and control light that way. Will always be wide open with this adapter. Main reason why I left canon years ago.

You need to buy an adapter for the wide angle, they are not canon. The two canon lenses work great. The 18 to 55 is a good all around lens. The package deal wasn't bad. I'm a little annoyed about the wide angles not being compatible.

If your lens has a 58mm front diameter. Its not very good tho, lots of distortion. You are better off getting a good wide angle lens.

Yes . . . FD-EF See: http://www.amazon.com/gp/product/B001D8X72G?ref_=pe_527950_33920250. I use it with all my old FD lens to adapt them to an EOS camera. I haven't really noticed any distortion. It even works on a doubler (2X) with long lens.
