Bought this lens cheap at an estate sale, but now I'm trying to figure out the adapter I need to get it to fit my Rebel XS body. I've looked at dozens of pictures on the internet, but cannot narrow down what this mount is exactly.
per request here are a few additional shots to show the flanges. 1st additional pic with the aperture bar at the top (like the previous pix) and the second additional pic at a slight angle to show flange definition, and the third additional pic with the aperture bar at the bottom to show flanges that weren't quite viewable in 1st pic.
Any help would be appreciated.
