Calculator cluster
Sensor & focal length
Crop factor, equivalent aperture, angle of view, field of view and print size from megapixels.
Sensor & focal length
Angle of View Calculator
Compute rectilinear horizontal, vertical and diagonal angles of view from focal length and sensor width and height.
Sensor & focal length
Crop Factor Calculator
Get sensor diagonal, crop factor versus 36×24 mm full frame, and 35 mm-equivalent focal length from your sensor size and lens.
Sensor & focal length
Equivalent Aperture Calculator
Convert an f-number through crop factor into a full-frame-equivalent aperture and the DoF stop delta. Exposure on the sensor stays the f-number you set.
Sensor & focal length
Field of View Calculator
Turn focal length, sensor size and subject distance into frame width, height, diagonal and area in metres — useful for lighting and group shots.
Sensor & focal length
Megapixel Print Size Calculator
Turn megapixels, aspect ratio and DPI into pixel dimensions and print width/height in inches and centimetres. 300 DPI is the usual photo-lab start.
