Frequently asked questions#

What is the crop factor of 1/1.7" sensor?

4.55× (diagonal 9.5 mm vs 43.3 mm for full frame).

How big is a 1/1.7" sensor sensor?

7.6 × 5.7 mm, an area of 43 mm².

Is 1/1.7" sensor good in low light?

At the same exposure it gathers 4.3 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.
