Both were taken with D7100 with an 80-40mm lens at the full length. The first was hand held at IS0 100, at 1/640 sec at f8. The second was on a tripod with a ball head mount, at ISO 250, 1/1000 sec at f7.1. Some of the selection is whatever works for you, and whatever the lighting and other issues demand or permits.
