    A-1, AE-1, FTbn, FD lenses: 28mm f2.8, 35mm f3.5,50mm f1.8, 50mm f1.4, 100mm f2.8, 200mm f4, 75-150mm f4.5 zoom Tokina FD fit 300mm f2.8, extension tubes, Gift CANON 1000F + kit lens and a Sigma 70-210mm, Gift CANON EOS 300v + 28mm f4-5.6 and 75-300mm f4-5.6
    I was given a 1000Fn mint with case including a SIGMA zoom UC AF 70-210mm f4-5.6 then later a 300v . I find the Sigma zoom works on the 1000Fn but when I attach it to 300v the small screen on back goes 'blank' and lens will not work ! Why does it work with 1000Fn and NOT with 300v ? Strange !

    Pete,

    I could be wrong with this. But I think that it has something to do with the chip in the Sigma lens. The only work around is to have the chip replaced. Clearly not worth it in this case.

    I seem to remember back in the day, you could send the lens off to Sigma to have it done.

    I could be wrong, please anyone out there feel free to correct me if I am.

    Gary
