### 5/5 — DOF Calculator

*2012-11-15*

This is probably the best calculator I have used. It is perfect for the professional photographer as it allows the coc to be changed to suit the quality from large megabyte modern sensors.
If you use a D800, for critically sharp results set the app to D800, Custom COC of 7, yes 7

Although handy, I would like the option to remove the Angle of View display and allow it to be used in landscape mode on the Ipad

Keep up the good work, this is top notch.
