A long time ago I was quite involved in film photography and now want to get into DSLR. I have some equipment left and wonder if any of it is worth using or if I should start with all new (or recent used)? Obviously it is the lenses I am considering, although I'm not sure what to do with the rest of the stuff?
Canon EOS 650 Body w/Tamron AF LD Aspherical 28-200mm 1:3.8-5.6

Canon EOS Rebel G w/Canon Zoom Lens EF 35-80 mm 1:4-5.6 III

Nikomat w/Nikkor1:1.4 F 50mm Lenz (my favorite), a vivitar 135mm, a Vivitar 28mm and a 2X extender.

I recognize that the Nikor compatable stuff is not AF, but I still don't know what to do with it?

Thanks,

Rich
