Hi, I am thinking of purchasing a 2X canon extender. It would be used with my 100 to 400 telephoto on a 70D body.
I have been advised that getting a mark 2 would be virtually as good as getting the newer mark 3 and of course a lot cheaper.
Does anyone have any opinions on the merits of the Mark 3 over the 2, with the set up I am using.
