5DMK III 600f/4 V2, shot @ f/4.5 & 1/160th ISO1250
Right on Sundown, Mala Mala South Africa March 2013, had to use the 600 as the Mother was right on top of her young Cub & the Cub was not used to the vehicle, haven't had a lot of opportunity yet to use this Lens, mostly it's been the 300f/2.8 & 400f/2.8 V2's, but like it so far.
