Thank you. That is Indian eagle owl. All my other lenses are collecting dust
How many AF points work with the 2xIII on the 1DxII?
I thought I heard that it only allowed center?
I would be a bit sad if I only had centerpoint with the "800/8DO II IS" on the 7D3.
I saw a Canon list of TCs and lenses for the 6D2, and was shocked to see that the 100-400II at f/8 allowed multiple f/8 AF points, but the 400/DO II IS at f/8 only allowed centerpoint. This is odd, because the DO II is very sharp and AFes so well in general. Maybe it's the diffractive optics, making the slightly OOF areas too sharp and edgy? My 7D2 focuses the DO II at 1120mm f/11 slowly, but perfectly, in Live View.
I'd be happy just to have f/8 at the nine center points, because 9-point does not hunt anywhere near as bad as single-point in poor light or busy backgrounds.
