Hi, I got a used Tamron 90/2.5 (49mm thread) but it has the wrong Adaptall mount. I don't know much about these mounts, any references? What I am looking for is info on whether Adaptall and Adaptall 2 adaptors are usable with this or only one type. Is it still the consensus that KA Adaptalls are problematic? Are suitable Adaptall mounts available new and is it recommended against buying used?
Thanks, Kostas
