"A Vivitar 2x converter" and my "Vivitar Auto 2X Custom Tele-Converter" may well be two different things... As you may well know, there are converters, and there are converters. Some of the 6 or 7 element, well-corrected converters are excellent. I just don't know what it is I have, and how corrected it is.
I also have a Rokunar 2x converter for my K-mount stuff. I don't know about that one, either! I've been trying to find a site that discusses converters, and so far have been singularly unsuccessful! keith whaley Pat White wrote: > > Back in the 80s, I used a Vivitar 2x converter with my MX, with the M200 f4 > lens, as well as the K45-125 f4 zoom, and the results were horrible.
