Depth of field, hyperfocal distance, field of view, and crop factor calculators.
Calculate the depth of field for any lens, aperture, and subject distance combination.
Find the hyperfocal distance for maximum depth of field from half that distance to infinity. Essential for landscape photography.
Calculate the horizontal, vertical, and diagonal field of view for any focal length and sensor size.
Calculate equivalent focal length and aperture when using lenses on crop sensor cameras. Compare the effective look across sensor sizes.
Calculate magnification ratio and working distance from lens focal length, minimum focus distance, and extension tubes.
Calculate the Airy disk diameter at each aperture to find the optimal f-stop before diffraction softens your images.
Calculate the size of background blur circles for any lens, aperture, and distance combination. Compare bokeh across setups.
