Have had it for a couple of weeks, but only tried it in the neighborhood. I still need some time to get used to having zoom on such a big lens, but it´s coming.1DX, 560mm, f5.6, 1/250s, ISO1600, handheld.
400mm 1/1000 f/4
First post:Have had the lens for about one year now. I use it daily and love it all focal lengths; with and without extender employed.This at 560mm on 1DX
