The problem in rec.photo.digital is that our favorite troll(s) have a cursory knowledge (at best) of digital photography (and photography in general) but they have an almost desperate need to try to convince others that their personal choice of equipment is the best for everyone.

Navas has been complaining about Canon's switch from FD to EOS for years, if not decades, even back before everyone started kill-filing him. It's true, Canon made a clean break with the EOS system, but there were two different FD to EOS adapters sold, and of course FD systems did not instantly stop functioning when Canon moved to EOS. There are still good FD to EOS adapters being sold, Bob Atkins has a good review of one ($125) on his site, "http://www.bobatkins.com/photography/reviews/canon_fd_eos_adapters.html".

Except you have no experience or knowledge of photography, so not terribly surprising that you don't show any work. >Ironically, Many older Nikon lenses can't be used on later Nikon bodies, >or they have to be sent in to be modified. Yet again you display your painful lack of knowledge. >Navas has been complaining about Canon's switch from FD to EOS for >years, if not decades, even back before everyone started kill-filing >him.

And if you really know anything about it, you would know the adapter simply doesn't work for the majority of FD lenses. But you just "know" what you've seen on the Internet, so your glaring errors aren't terribly surprising. -- John "Facts? We ain't got no facts. We don't need no facts.

Perhaps you could explain that to me. specs HAVE to be documented. Releasing involves publishing on a web page - for which the return is less that you have to develop. |
