I recently acquired a Canon 70-200 f2.8L IS II USM lens and want to add a 2X extender. According to Canon, the newest EF 2.0X III extender is only compatible with the EF 70-200/2.8L, EF 70-200/2.8L IS, and EF 70-200/4L L zoom lenses. It seems likely that Canon WOULD include later 70-200L lenses like mine if they are also fully compatible. Or did they just neglect to update the description with later model 70-200 L lenses? Can anyone definitively confirm that the Canon EF 2.0X III is compatible with my 70-200 f2.8L IS II USM lens, and if it isn't which 2.0X model is best for my lens? Any info and/or links would be much appreciated.
On the page of EXTENDER EF1.4X III / EF2X III Instruction Manual I see EF70-200mm f/2.8L IS II USM is compatible with the extender. Here is a snapshot:
