Releasing involves quality control and legal costs. Then there are support costs, usually the biggest costs of all. The lower the documentation and release investments, the greater the support costs tend to be.

Yes, that's true, but Nikon was the predominant SLR system manufacturer prior to Canon coming out with their EOS system, so there were a lot more lenses to begin with. The lower end Nikon D-SLR bodies can mount the AF and AF-D,but they can't auto focus with them because the mount lacks the screw drive. > and neither one worked well. one has an optic and functions as a weak > teleconverter and only works with a few lenses and the other does not > have an optic and precludes infinity focus. The present one being sold works okay. The professional one sold by Canon was very good. In any case, Canon really had no choice but to upgrade their mount, and making a clean break enabled them to avoid many of the problems that plague the current Nikon mount.

I owned a Canon FD 300mm 2.8 for twenty+ years and the adapter kept it useful for almost half that time. The only "problem" was that I had to *focus* it. Wasn't a big deal, since I came up when a photographer had to do such 'troubling' things like that and *meter* the exposure. I knew a SI shooter who liked Canon glass so much that fabricated an adapter to use FD lenses on his Nikon bodies in that era (late 70s - 80s). NavASS's bitching, moaning and stupid little quotations do nothing than prove that he doesn't have a single original thought in his pointed head... |
