Hi Dennis:

I'm afraid there is no good way. There are 2 options available, which might be of some use:

1- You can get an FD/EOS adapter for macro use. This is a metal ring that allows your lens to mount to the DSLR, but because the EOS body is thicker than the A-1 body, the lens will not focus to infinity. How far out you can focus will vary depending on the length of lens you attach, but nothing will go out very far. It may be useful for closeups if you do a lot of that kind of shooting.

2- There are also FD/EOS adapters that offer infinity focus. However, these do this by adding a glass element in the adapter. This glass element degrades image quality so that you can only use the lens stopped well down, and then with less sharpness than you're used to getting. In addition, this element magnifies the image, and this magnification is in addition to the "crop factor" of the smaller DSLR sensor, which in most models is already a 1.6:1 enlargement. If you use one of these on a full frame DSLR like the 5D, the sharpness issue gets worse because the sharpness degrades toward the edges of the field. All in all, you're better off looking for equivalent EOS lenses... since this system has been around for a long time now, you can find used ones pretty easily to lower the cost.

One other possibility is to use an Olympus DSLR instead of a Canon. These bodies are shallower and can accept the FD mount on an adapter without the infinity-focus problem. The crop factor on these cameras is 2:1 due to their even-smaller image sensor, but if that's OK this is a better way to make use of the FD lenses.

Also, be aware that the focusing screens in AF cameras are not really designed for manual focusing. You will be able to accurately focus your FD lenses at apertures of about f/4 and smaller, but you'll get erratic results trying to focus an f/1.8 manually at full aperture unless you change the focusing screen.

Is any way to use my A-1 FD lenses on any Canon digital camera?

Hi Mike:

My take on it is that the filter is a flat plate that is within the cone of rays between the lens and the film; because the lens was designed to have this filter in place, and the plate will deflect angled rays in the corners of the image but will not deflect axial rays in the center, the effect of the filter being missing would theoretically cause some unevenness of sharpness across the field - something like a curvature of field aberration. However, I think this effect is so small that it would likely be undetectable among other aberrations and focusing error that are present in any image.

I don't have an official answer, and I don't have your particular lens; but I did an experiment with a 500mm f/8 Tokina mirror lens to get a sense of the effect of a missing filter (they seem to be ALWAYS missing from used lenses). Click on the "home page" link on this message to see the results of that very informal test. Admittedly, my standards here are not the highest - I shoot handheld, and at relatively high ISO settings - but I could not detect any benefit gained by the presence of the filter overall.

If that link doesn't work, cut and paste this:

I just received a 500mm f/5 which is in remarkably fine condition and according to the serial number was made between 1966-68. There is no instructional literature included however.
I noted in your report that the insertion of a 39mm filter was "required" before attaching a camera body. This is problematic for me as the filters included are all colored (no ND or UV).
Can you please tell me why the filter is necessary (the lens seems to produce excellent images withOUT a filter in place)?
Also is there still a source for a 39mm UV filter?
Thank you so much for your informative site and I will appreciate any informationou ma be able to provide me regarding the filters.

Hi Les,

This add on eBay might interest you (link below).
If your lens is the same, it is worth quite a bit.

Just Google "Nikkor 2000 mm" and you'll find some other items sold at interesting prices!

Best regards.

Les,

As you are in the UK contact Ffordes Photographic in Scotland. They buy or sell on commission and were always very generous when I dealt with them and their valuations are spot on. The value of your lens will depend the condition of the optics and any cleaning costs involved

I wonder if any-one can give me an idea of what my lens is worth - I have a nikkor 2000mm reflex lens which I bought quite a few years ago with several cameras.
It hasn't been used for a long time and I'm thinking about selling it.

Hello Kim:

Your 75-300 zoom lens will fit on current Nikon digital SLR cameras. The light meter may not work with this lens mounted, depending on the camera model.
