I was considering purchasing an extender for my Canon EF 70-200mm F4 and see there are 1.4x and 2x variations in the canon range together with multiple versions of each.
Does anyone know what the difference is between a mk1 and mk3 version of the 2x extender for example?
(by the way I will only be manually focusing with the extender as I know there are limitations with the F4 and extenders and hunting in auto focus)
