As a Wildlife Photographer I use the 2x Extenter on the 600 f4 regulary and then end up with an F8 Lens setup of course.
With the current 1DX the F8 Lens setup is usable in many situations for myself - eg for moving subjects like consitent flying birds in flight. However - when it comes comes to image composition it can be really a mess having to use the central AF point only.
For non moving subjects the back focus AF technique is a workaround of course - but if the subjects moves (eg head) I would strongly prefer to be able to use servo AF - especially when the subject may have come really close and DOF is super - narrow. Changing extenters is not an option for my style of shooting due to enviroment / fear of subject etc.
So speaking for myself the "number one killing feature of a new Canon 1D is implementation of (much) more usuable AF points with F8 lenses.
Anyone to agree?
