An afternoon with wetland birds Cormorants a great bird to spend time with your camera kit from a hide or along a river bank using a bag hide I photograph this bird with a Nikon D850 fitted with a Sigma Sports lens focal length 150-600 zoom a lens i class as the ideal carry about lens a hefty pice of kit but well worth the results crisp and clear through the full range add a morning zeroing the lens and the results are outstanding using the custom mode 1 on the side of the lens adds speed to the auto focus. Running out light add two stops by using the custom image stability on the lens. The imagery above was shot at different focal lengths through out the zoom range.
