Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Photography
Crop Factor Calculator
Calculate the full-frame equivalent focal length of a lens on a crop-sensor camera by multiplying the actual focal length by the sensor's crop factor. Use it when comparing lenses across systems, predicting field of view, or planning gear purchases.

Photography
Field of View Calculator
Calculate the horizontal coverage width (and height) at a given subject distance for any lens, sensor, and crop factor combination. Perfect for planning surveillance setups, portrait framing, or landscape compositions.
