    I just bought this Vivitar 28mm and I am not sure what lens mount it is so I could purchase the correct adapter for it on my EP1

    Got the same ; it's a TX mount. Yours has already a TX -> smthg (Canon FD by the look of it) adapter locked on, but you can remove that and find any other else better suited to adapting the lens on :43:

    See : SLR Lens Mount Identification Guide

    Cheers,

    (just took some pics of mine with TX->OM adapter both on and off)

    thanks, looks like I missed a tiny label saying C/FD on it. One thing is, I removed part of the adapter, and it looks slightly different from yours, I think I didnt fully remove the adapter?

    Also I think the aperture blades are oily and are stuck at fully open, as I do not see the blades. Is it worth trying to fix the oily blades?
     
  4. I don't know if the lens is old enough to be a TX, but the important thing is that it is a Canon FD mount. To check if the diaphragm is working set the lens aperture to something less than f2.8. You need to rotate the smaller lever anti-clockwise and hold it in position, and then rotate the larger lever in the same direction. The small lever engages the diaphragm mechanism when the lens is mounted on a Canon camera (or adapter) and automatically rotates when the lens is mounted, and the larger lever is the stop-down lever. On a m4/3 to FD adapter this second lever in permanently engaged. This is the only way to check if the diphragm is operating correctly when an FD breech-lock lens is not mounted.

    I didn't knew there were native, non-TX, versions of this lens, but you appear to hold a genuine Canon-FD mount one. In any case, no screwdriver should be involved in the removal of a TX adapter. There's a tiny lock marked 'O<-->L' at the bottom of the lens to release the adapter. If you don't have that lock, screw your mount back on !

    Cheers,
