PanoCalc app for iPhone and iPad

PanoCalc is both a field of view calculator for digital cameras and a panorama calculator.

If you are choosing lenses or choosing between cameras of different sensor sizes PanoCalc quickly tells you the field of view your pictures will have. And if you are planning to join a few of those pictures into a simple panorama, or to make spherical panoramas for VR, or to create gigapans with dozens of pictures then PanoCalc will do all the calculations you need.

Features:
• Presets for popular sensors,
• 3:2 and 4:3 aspect ratios,
• Numerical sensor inputting and my sensor recall,
• Normal or fisheye lenses,
• Portrait or landscape picures for panoramas,
• Pictures per row and overlaps
• Up to 10 panorama rows and overlaps,
• Optional calculations for zeniths and nadirs.
