I’m still getting to know the new lens, so the first couple of shots here are by way of demonstrating just how good the 100-400 Mk II is in what are undoubtedly poor conditions. It’s sharp at maximum aperture, and the stabilization is extremely solid. Both these shots were taken before the sun had risen over the South Downs. ISO is 1600, and the aperture f5/6 (i.e. wide open). The lens is at a full 400mm extension. Shutter speed is 1/80 (rat) and 1/100 (robin).

Rat in tree at Falmer, 1/80, f5.6, 1600 ISO

Robin at Falmer Village, 1/100, f5.6, 1600 ISO

The rest of the days shots were is slightly less poor conditions. A cormorant was the morning highlight, circling Falmer several times.

The final shots were taken in the afternoon, at the edge of the car park at Mithras House (on one of the main roads into Brighton). The robin was happily and boldly chirruping away.

Camera note: all photos taken with the Canon 7D Mark II and EF 100-400mm f/4.5-5.6L IS II USM lens.
