Frequently Asked Questions
Common questions about Crop Factor Equivalent Focal Length, formulas, and expected usage.
What is crop factor in photography?
Crop factor describes how much smaller a sensor is than full-frame and how that changes field of view for the same lens.
How do you calculate equivalent focal length?
Multiply lens focal length by crop factor to estimate full-frame equivalent focal length.
Does crop factor change actual lens focal length?
No. The physical focal length stays the same; crop factor changes how much of the image circle is captured.
Can I estimate equivalent aperture too?
For depth-of-field comparisons, photographers often multiply f-number by crop factor as an approximate full-frame equivalent.
