a long time ago Posted August 31, 2005 Share Posted August 31, 2005 the sigma 500mm/7.2 APO I just got from KEH is giving me error 99...should I try an exchange or just give up ...serial #1006596.....I'm looking for a cheap, slow lense to put on my backup body for when I'm out shootin' birds.

mark u Posted August 31, 2005 Share Posted August 31, 2005 Sadly that lens is from a generation of Sigma lenses that aren't compatible with later EOS bodies and it can't be rechipped to work with them. I know that KEH always attaches a warning to its listings of incompatible lenses, so it seems you missed the warning when you bought the lens. The lack of compatibility is one reason the lens appeared to be cheap. Link to comment Share on other sites More sharing options...
ralph_jensen Posted August 31, 2005 Share Posted August 31, 2005 Mark is right, alas. I have that lens and loved it on my film cameras, but it won't do a thing on my digital bodies. Not sure what to recommend in its stead. Link to comment Share on other sites More sharing options...
kbreak Posted August 31, 2005 Share Posted August 31, 2005 I'd recommend not buying Sigma, that's what. I had great hopes for the Sigma 28 f1.8 and when I got my digibody... it became a paperweight. *cries* Link to comment Share on other sites More sharing options...
yakim_peled1 Posted September 1, 2005 Share Posted September 1, 2005 Try to mate it with a D30. This is the oldest Canon DSLR so it may work (tough I doubt it). Used D30 bodies may still be in the shops and are very cheap. Go to a big store and try. But hey, is this lens optically any good? It's a prime but it's a very old Sigma prime. In the end, as you found out for yourself, YGWYPF. Happy shooting, Yakim. Link to comment Share on other sites More sharing options...
richard_tynan2 Posted September 1, 2005 Share Posted September 1, 2005 I tried a couple of old (mid 1990's) Sigma zoom lenses on a EOS 10D and found they do work ok if the lenses are used wide open. Stop them down and you get the error. Not ideal, but if the 500/7.2 works wide open it might be better than nothing, especially if it is primarily for birds.

leeuwtje Posted September 1, 2005 Share Posted September 1, 2005 My Sigma 400 5,6 didn't work with the 10D and 20D, but does work again with the 350D. So maybe in the future :) Link to comment Share on other sites More sharing options...

leeuwtje Posted October 18, 2005 Share Posted October 18, 2005 Mark U, I have the 440 5,6 APO Macro version. Not the HSM. So I was very happy to find out it still works flawless. Link to comment Share on other sites More sharing options...
