The mount type you are talking about is most like the Vivitar TX mount (it might be T-4). It is Vivitar's answer to the Tamron Adaptall system, but not nearly as prolific or successful. I don't believe there was ever a TX or T-4 adaptor made for EOS. You can probably find a T-4 or TX adaptor to adapt the lens to M42 screw and then an M42-EOS adaptor to make it work.

It was $200 new. It's been a great lens, but I only use it in summer in full daylight. I am considering updating the t-mount with an EOS mount, but the Vivitar adapter mount is not a screw mount... it is a triple pin / groove mount (I don't know if there's a proper term for that). On my 1.6x equiv. Canon XTi the 500mm would be the equivalent of an 800mm cat lens! I have a Vivitar 500mm f/11 cat with Canon FD mount adapter and rear element screw-on filters. It was $200 new.

You're right, of course... it's the in-camera "crop" factor is what I was referring to when I mentioned magnification. And you're right about another thing - one can get rid of all the complaints regarding the Mirror (and other old lenses) with digital post-processing. The contrast can be improved greatly even with the simplest of software, including Picasa. Have you looked into any of the cheaply available super long T-mount lenses? The old Spiratone 400mm f/6.3 and Toyo 500mm f/8 long tubes are feasible to handhold now with a higher ISO speed and Image stabilization. You will be pleasantly surprised. I've a couple of posts on that subject, if you're interested. AJ Thanks for the thoughtful comment, Cliff.

One thought on lenses, mirror and otherwise, on digital cameras. The digital sensor, APS-C on the Sony Alpha, has an aspect ratio of 1.5:1 compared to a 35mm film frame. That makes the field of view on a 500mm lens the same as a 750mm lens on film. It does NOT give the magnification of a 750mm lens. Straight out of the camera the Soligor C/D mirror and and an old Kimunor 500mm preset lens are giving me very similar images, the most noticeable difference is that the Kimunor has a little more contrast. Kimunors millimeters also seem to have been very slightly longer than the ones Soligor used. I am finding that nearly all the complaints about mirror lenses (including contrast) are resolved with a digital camera and/or digital processing, right down to the donut bokeh. Although the optical viewfinder still looks like f8, with the 3 stop digital advantage provided by the combination of faster ISO and anti-shake this is the equivalent of a 500mm f2.8 lens! While digital technology does not make it longer, it does make it faster. Thanks for a wonderful and thoughtful blog.
