Superb App
Calculating DoF is one thing, but this goes beyond that. The Pixel Peeper mode constrains the DoF to even tighter tolerances. Awesome when trying to REALLY nail focus. It enables sensor MP adjustment to fine tune the calculation. For example, with my 30MP body and an 85mm lens…shooting at f/1.8 @ 15ft, the DoF is 5.40”, but that same lens on my 50MP body yields just 4.18.” Versus a DoF of 11.68 as a generic “35mm” calculation. There’s “acceptable” focus and then there’s actually sharp focus. It can make a huge difference when printing large. The included ND Filter Calculator is also very handy. Start with a base shutter speed, tap the ND filter (or several) and the new shutter speed is instantly calculated. It even includes a timer for those that don’t have, or don’t want to use, an intervalometer. Slick
