Frequently asked questions#
What is the crop factor of 4 × 5 inch large format?
0.28× (diagonal 155.1 mm vs 43.3 mm for full frame).
How big is a 4 × 5 inch large format sensor?
121 × 97 mm, an area of 11737 mm².
Is 4 × 5 inch large format good in low light?
At the same exposure it gathers 3.8 stops more total light than full frame, so expect roughly that much less visible noise at equal print size. Modern processing narrows but doesn't erase the gap.
