Yes I know that there are already many topics reguarding this, but mine is a little different.
I don't shoot that much wildlife, actually, hardly any at all. Most of my animal shooting is my two rat terriers.
To the question, for Photojournalism, people, travel, the odd bit of indoor sport, and a fair bit of aviation would a 70-200 f/2.8L IS + 1.4x TC provide a better, more versitle, sharper combination over the 100-400L IS?
P.SThis will be complimented by a 16-35 f/2.8L
