I recently acquired some lenses off ebay, at the advice of my mother, but am having trouble determining which ones are which. I have tested 9 of the 20, and have taken pictures of the 11 I haven't been able to identify. (http://www.photo.net/photodb/member-photos?user_id=7084563). Really, what I want to know is if there are adapters for them. I know one is an interchangeable bayonet, but don't know where to find that plate. I have a Canon Rebel 2000 SLR and a Canon Rebel XS DSLR. I have two mount adapters already, a Fotodiox M42-EOS V.2 and a Fotodiox Nikon-EOS, just want to know what else to buy. Here's a list of all the ones I bought. For Vivitar TX Interchangeable Bayonet Mount: Auto Vivitar Tele-Zoom 90-230mm F4.5 Lens - Lens K For Minolta MD Bayonet Mount: Prospec Zoom 70-210mm F4-5.6 Lens Albinar ADG MC Macro Zoom 80-200mm F3.9 Lens Auto Vivitar Tele-Zoom 85-205mm F3.8 Lens For Pentax M42 Screw Mount: Soligor 450mm F8 Lens Super Cosina 80-200mm F4.5-5.6 Lens - I know I have tested these For Pentax K Bayonet Mount: Samyang MC Auto Zoom 28-70mm F3.5-4.5 Lens Kiron Kino Precision MC Macro Zoom 35-135mm F4 Lens Sears Multicoated Auto Zoom 80-200mm F4 Lens Rokinon MC Macro Auto Zoom 80-200mm F4.5 Lens Sakar MC Zoom 80-200mm F4.5 Lens For Canon FD Bayonet Mount: Vivitar SMS MC Macro Focusing Zoom 28-85mm F3.5-4.5 Lens Kiron Kino Precision MC Macro 70-210mm F4 Lens Canon Zoom Lens FD 70-210mm F4 Lens Focal MC Auto Zoom 80-200mm F3.5 Lens CPC Phase 2 CCT MC Auto Zoom 80-200mm F4.5 Lens For For Nikon Bayonet Mount: Aetna Rokunar Auto Zoom 70-210mm F4 Lens Rokinon Auto Zoom Super Coated 80-200mm F4.5 Lens Star-D C Auto Zoom 80-205mm F4.5 Lens Phoenix AF Zoom 100-300mm F5.6-6.7 Lens - I have tested these, I believe...I am not sure. So as you can see, I have tested Nine but can only identify bout 6 of them. Any help will be greatly appreciated. If you know which lens it is, please let me know the Lens letter and which one it pertains to. And any advice about what adapters I should buy would be appreciated. Thanks a million.
