Compare lenses across formats: a 35 mm lens on APS-C frames like ~53 mm on full frame. The calculator also shows the equivalent aperture for depth of field.
It works for full frame, APS-C (Nikon, Sony, Fujifilm and Canon), Micro Four Thirds, 1-inch and medium format.
FAQ
What is crop factor?
The ratio of the full-frame diagonal (43.3 mm) to your sensor's diagonal. Multiply focal length by it to get the full-frame equivalent field of view.
Does crop factor change the exposure?
No. f/2.8 is f/2.8 for exposure on any sensor; only depth of field and total light gathered change.
