Where the D7100 was rated as good for 950 shots on a charge, the Nikon D7200 should manage 1,110 shots on a charge. You can supplement battery life with the MB-D15 portrait / battery grip.

The Nikon D7200's four noise-reduction settings ("High, "Normal", "Low" and "Off") provide good flexibility in choosing how you want to make the trade-off between subject detail and noise levels.
