<p>Hi Philip, which digital bodies have you tried it on?</p>

<p>That's good to know, to my mind there's a clear pattern emerging now. To recap, the pre-10D models are 1DS, 1D, D60 and D30. From the sparse reports I've found on the web, all of these models have been reported to work, and I have found none to the contrary. This is encouraging to say the least!</p> <p>Bob may or may not have a point on firmware, but in the absence of Sigma releasing an official compatibility chart (don't hold your breath), user reports like these are the best we can hope for. At least, for those who aren't in a position to have their lens rechipped. The more the better, so please keep the reports coming in guys.</p>

<p>Thanks Ed, that's music to my ears. I've heard others say the same about those models, and none so far that have reported incompatibility issues, so there seems to be a growing consensus that they are broadly compatible with old Sigmas. In fact, of all the models mentioned in my first post, from what I've gleaned so far only the 10D seems to be problematic. This leads me to believe that (2) is the surest bet of those 4 options. I'd love to hear from some 10D owners that can corroborate this.</p>

<p>Hi Bob, thanks for replying. I'm aware that Sigma sometimes offer a re-chip service, however due to the size and weight of the lens, posting it would be a challenge. In any case, I believe this lens is around 20 years old now and so I have my doubts that Sigma (who are known for being somewhat reluctant to perform this task) would accept it.</p> <p>At this point I'm just looking for as much anecdotal evidence as possible for which legacy Sigma lenses work with which Canon bodies. There is such a dearth of reliable information on this subject that I hope this thread might shed a little more light on things.</p>

<p>Hi all, new to the forums but a long-time lurker!</p> <p>I have an old film-era Sigma 500mm f/4.5 AF APO with EF mount, and I'd like to know which digital Canons (if any) will work with it.</p> <p>There seems to be some conflicting information in this regards, but the general consensus seems to be that all DIGIC II and later models are incompatible with old Sigmas. More specifically, any aperture other than maximum (e.g. f/4.5 on the 500mm) will result in an err99 error.</p> <p>All fine so far, however there are conflicting accounts about compatibility with earlier Canons, which I've surmised below.</p> <ol> <li>All pre-DIGIC II DSLR's are compatible with old Sigma lenses (i.e. 300D, 10D, 1DS (Mark 1), 1D (Mark 1), D60, D30)</li> <li>All pre-10D models (i.e. 1DS (Mark 1), 1D (Mark 1), D60, D30)</li> <li>Only non-DIGIC models (i.e. 30D and 60D)</li> <li>No digital at all.</li> </ol> <p>If anyone has first-hand experience with using old Sigma lenses with these models, please post your findings below. I'm especially interested in hearing from 1D and 1DS owners.</p> <p>Thanks! :)</p>
