Extremely well thought out UI

I was previously using a laminated dof/hyperfocal chart for my 1.6x crop factor digital SLR. When I recently upgraded to a full-frame SLR, I realized I needed a new chart.

Fortunately I thought to check the app store for a dof calculator. This app was EXACTLY what I was looking for, and is much, much easier to use in practice than a chart. No mental gymnastics: just tell the app what body, lens, and zoom you are using and then fiddle with the aperture and focus point sliders until you get the hyperfocal point and dof you desire.

This UI was clearly designed by a photographer. Very, very nice, and even a couple bucks cheaper than the nice little chart I was using!
