neil_g Messages 30,364 Name Neil Edit My Images No 1 Jul 2009 #4 here you go: http://www.sigma-photo.co.jp/english/support/faq/condaitr.htm (that is a sigma TC compatibility list but i cant see them being too different to canon TCs)

neil_g Messages 30,364 Name Neil Edit My Images No 1 Jul 2009 #7 the only thing i can think of is that the canon TC protrudes more into the rear element than the sigma will allow?

neil_g Messages 30,364 Name Neil Edit My Images No 1 Jul 2009 #9 you should be able to test if it is definately the case with the sigma lens on the canon TC. try attaching the TC while the zoom is set to 200? (should move the rear element into the lens further?)
