Camera Sensor Sizes & Crop Factors
Compare silicon surface areas from 1/1.3" smartphones up to 44x33 Medium Format. Calculate exact 35mm equivalent focal lengths and bokeh depth of field.
Select Digital Camera Sensor Format:
Imaging Silicon Dimensions
APS-C (Crop Sensor) (1.5x)
📐 23.5 x 15.6 mm (367 mm²)
Popular Camera Models:
Sony A6700, Fujifilm X-T5, Canon EOS R7, Nikon Z50
Field of View & Bokeh:
A 50mm lens behaves like a 75mm telephoto (1.5x reach multiplier). Great for wildlife and sports without expensive telephoto glass.
Low-Light & Dynamic Range:
Gatherers ~42% of the light of full-frame. Slightly deeper depth of field at equivalent f-stops.
