CropFactor: Lens + DOF Calc

CropFactor returns the full-frame-equivalent focal length and DOF-matched aperture for any sensor size, plus hyperfocal distance and depth-of-field near/far at your subject distance.

SENSORS INCLUDED
- Medium format (54x40), Fujifilm GFX (44x33)
- Full-frame 35mm (36x24)
- APS-C Canon (22.3x14.9), APS-C Nikon/Sony (23.5x15.6)
- Micro Four Thirds (17.3x13)
- 1-inch (13.2x8.8)
- iPhone main (~9.8x7.3)

MATH
- Crop factor = full-frame diagonal / sensor diagonal
- Equivalent aperture for matched DOF = real aperture * crop factor
- Hyperfocal = f^2 / (N * c) + f, where c is the circle of confusion
- Default CoC = sensor diagonal / 1500
