Frequently Asked Questions
What is camera sensor crop factor?
Crop factor is the ratio of a 35mm full-frame sensor diagonal (43.3mm) to a smaller sensor’s diagonal (e.g. APS-C = 1.5x, Micro Four Thirds = 2.0x).
How does crop factor affect lens focal length?
A 50mm lens on an APS-C sensor (1.5x crop) produces a field of view equivalent to a 75mm lens on a full-frame camera.
