Hi. Yesterday I asked about using my old Tamron lenses and was asked to post pix. It seems I can't according to the rules? I have had a closer look at the gear and can tell the following. The 2x tele converter fits the body with no adaptor ring. Then the 28-58mm lense, the 75-250mm zoom and the 500mm fixed lense all fit using adaptall 2 rings. My original question was can I use these old circa 1980 lenses on any DSLR body? I will obviously save myself a bundle if I can and I'm prepared to accept that the newer stuff will be better (?) but at least I can hit the ground running and upgrade over time. A previous reply indicated that I might have to set exposure and focus manually. Manual focus doesn't TOO bad but manual exposure? Is this a major problem to an amature? Thanks to all those who educate us "noobs"!
