N[G10] x 2.28 = N[E-3]
Anyone with two different cameras and known sensor sizes can do this test and see it for himself. I don’t have any full frame camera, but I have a Canon G10 and an Olympus E-3.
The Canon G10 has a sensor size of 7.6 x 5.7mm, an area of 0.43cm² and against the full frame cameras with 36 x 24mm sensors it has a crop factor of 4.6x.
The Olympus E-3 has a sensor size of 17.3x13mm which gives an area of ~2.3cm² and against the full frame cameras it has a crop factor of 2x. The exactly calculated area crop factor between the full frame and Olympus is 3.84x based on Olympus sensor size of 17.3 x 13mm.
The Canon G10 has a crop factor of ~2.3x (exactly 2.28) against the Olympus cameras and the area of the Olympus camera sensors is 5.23 times larger.
