Preguntas Frecuentes
What is crop factor?
The ratio of full-frame sensor diagonal to your camera's sensor diagonal, multiplying your lens focal length.
What is the crop factor for APS-C?
Approximately 1.5x for Nikon and Sony, 1.6x for Canon, meaning a 50mm lens behaves like 75-80mm.
Do I need to know crop factor?
Yes, it helps understand field of view, depth of field, and equivalent perspectives across different cameras.
Does crop factor affect depth of field?
No, depth of field depends on actual focal length and aperture, not crop factor. It only affects field of view.
How does crop factor apply to phone cameras?
Phone sensors are very small, resulting in extremely high crop factors, causing all lenses to act like telephoto lenses.
