I was wondering if Sigma lenses are EF compatible. Some of the new Canon DSLRs (full frame ones) don't support EF-S lenses so I

was wondering if Sigma (Canon mount) lenses are EF or EF-S compatible. Personally I have to Sigma EX lenses.

The Sigma are compatible with Canon dSLRs!

The 'DC' lenses which are EF_s compatible, are the ones that will vignette on a full-frame... The 'DG' series are all full-frame lenses and 100% EF compatible - I have a lot of EX's myself

-> Your 15-30 EX, 50-500 EX, and the 70-300 APO you are looking @ are all full-frame lenses!
