Instead of getting much more glass for long shots, I was wondering if anyone has solid experience using either 1.4x or 2x extenders with the latest 70-200.
My main concern is image quality. Knowing that the more one magnifies an image, the worse the IQ can get is my main concern, but the 2x appeals due to my long reach needs.
Maybe the 1.4x is the best option, but then I only get 280 at the longest end.
Any comments from experience with either of these setups? Thanks.
