Hi,


Can anybody help me with a dilemma I'm having?


I am about to upgrade from my Canon 40D. Please bear in mind that I shoot wildlife and therefore the crop factorwill come into play.


My two options to upgrade to(both costing approximately the same) are as follows:


Canon 1D mark4 and my current 300L F4 lens


Pros and cons: Smaller crop factor. Better image quality (can I crop tighter?). Autofocus will work on the lens with a 2x converter. Less noise, so therefore faster shutter speeds


Canon 7D and a new 300L F2.8 lens


Pros and cons


Faster autofocus with the combination??? Larger crop factor. Better quality images with the lens, (but not necessarilythe camera).


Anycomments on this will be gratefully received,


John
