[edit] -- I might've figured this out -- the angled/beveled adapter under the other adapter was also removable. Once removed, it looks like I could then use a T Adapter for Canon. Thinking the adapter is FD lens mount since it's obviously not EF and it does say For Canon on it :) [/edit]

Hey ya'all. I bought the following lens on eBAY (please don't flame -- it was cheap! :))

http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&item=120955365515&nma=true&rt=nc&si=q0XQh0RvmbNciQZEDvox40hPVDc%253D&orig_cvip=true&rt=nc

I got it today -- aside from the fact the middle section was crossthreaded (lol) it looks like an ok lens. It came with a twist type adapter for quick fit -- but I'm not sure what I need or how I'm supposed to make it work with my camera. From looking at some others, it would appear a T Lens adapter is needed...but even then, I'm thinking MAYBE whoever made this lens (Toyo) threw on suitable adapters for a bunch of different cameras and that maybe this is just the wrong one (misboxed, perhaps)? Any help much appreciated....I just know I can just throw it onto my T3i.

The pictures show the adapter that is on it - then a picture of the adapter off (took three small flat heads to set it to the lens body). Sorry about pic quality -- was just trying to work fast -- going on a trip tomorrow :)

T-mount is a generic screw mount type standard for telescopes, you will need this

to connect it to your camera.

T-mount was commonly used for 3rd party lenses many years ago before we had electrical connections, autofocus, etc.  It was a way to let lenses be easily adapted to various cameras.  Its still used on all manual lenses like mirror lenses.  The main use now is for microscopes and telescopes.
