ef 400mm f/2.8l is iii usm

[MontanaDave]

I rented this lens for my R5 and then bought it used.
I love this lens. My primary lens was the RF 200-800 which was F8 "wide open" at 600 mm,
so it struggled in low light, before sunrise photos.
Most of my photography with the 400mm is big game, so for me it is perfect.
