Does anybody make such a thing? I have found lens attachment rings with tripod connectors but I loose auto focus and metering. I have a couple older lens that need one. My Tamron 60-300 is a log. I can't imaging hanging that thing off the front of a camera without support. It's a fun older manual focus lens that with great IQ but for me is almost impossible to handhold and focus. Did a quick search on Amazon and didn't see one. A couple of the longer Minolta auto focus lens are pretty heavy also. On the other hand if I loose the auto functions it will put my new Gossen Digi Six to work.
