Hi,
I'm looking for a lens to use on safari for both mammals and birds (main focus is birds) and am thinking of maybe the 70-200 f2.8 IS USM II along with a 2x Mk3 converter. I've previously had a 100-400, but found it far too variable in IQ, so now use the prime 400 f5.6, but feel that may limit me with the larger mammals I'll hopefully be seeing! I'll be using it with a 7D and don't wish to be changing lenses hence looking for an single alternative to the prime.
Has anyone had experience of this lens, especially when used with the 2x and can provide any thoughts on IQ etc?
TIA.
Cliff.
