damon_perrott Posted August 25, 2006 Share Posted August 25, 2006 I need help in identifying the various versions of tamron lenses. Ultimately, I want to use them on Canon EOS but I need help in being able to identify the mount style when shopping on ebay. Many sellers do not specify, they probably dont know. I have a list of tamron lenses via McBroom's camera Bluebook, but he does not specify which lenses came in which mount. Apparently there are Tmount, adaptamatic, adaptall, and adaptall 2 mounts. I actually bought a 135mm 2.8 marked -Auto Tamron (no.420102) with a nikon mount. Dont know how to tell which it is (excluding tmount). I have heard adaptall 2 to EOS mounts are rare now after being discontinued. How can i get a manual tamron lens to work auto-aperature if I cannot find an EOS to adpt2 adapter? Does anyone know of a web link of other useful source that lists or pictures new and old tamron lenses????thanks Link to comment Share on other sites More sharing options...
tommyinca Posted August 25, 2006 Share Posted August 25, 2006 You can get either an Adaptall Nikon, or Olympus or M42. From there, you buy the Nikon or Olympus or M42 adapter. Use two adapters to get to the EOS. Link to comment Share on other sites More sharing options...
damon_perrott Posted August 25, 2006 Author Share Posted August 25, 2006 thanks tommy. I do have a nikon/eos and m42/eos adapter and have used for my tamron and m42 lenses. They are a good solution to making these lenses usable. Correct me if im wrong however but i dont think it is possible to use these auto-aperature. thanks.

brucecyr Posted August 25, 2006 Share Posted August 25, 2006 Right, no auto aperture -- aperture, like focus, is pure-dee manual! It also looks like Tamron has cracked down on those who were selling Adaptall-EOS adapters. If you've got an exceptional Tamron lens, like the LD 300 f/2.8 or 400 f/4.0, it may be worth searching for an adapter, but otherwise its time to move on with gear appropriate for your new camera-to-be -- auto-everything and suitable coatings for digital use to boot!
