Re: My take on the RF 800mm f/11 DO IS STM for birds

Thanks for the feedback. I've seen a handful of reviewers show that the 800mm F11 is at least as sharp as the 100-500 with the 1.4 Ext. at 700 F10. The AF is lights out without the extender and still very good with it. How did you find the AF with the 800 F11? I know the focus box is smaller being at F11 which could present some issues with BIF.
