Frequently asked questions#

What is the crop factor of APS-C (Canon)?

1.61× (diagonal 26.8 mm vs 43.3 mm for full frame).

How big is a APS-C (Canon) sensor?

22.3 × 14.9 mm, an area of 332 mm².

Is APS-C (Canon) good in low light?

At the same exposure it gathers 1.4 stops less total light than full frame, so expect roughly that much more visible noise at equal print size. Modern processing narrows but doesn't erase the gap.
