Quote:It would be right if they had the same aspect ratio, but they don't (3:2 vs 4:3). It would be more appropriate to take the diagonal then:
ratio: 28.20656 / 21.640009 = 1.3034449
- EM10: sqrt(17.3^2 + 13^2) = approx. 21.64
- D7200: sqrt(23.5^2 + 15.6^2) = approx. 28.21
I agree that one should distract MP's to get a 3 x 2 MP count .
So 37mp would be a 3:4 sensor.
A 3:2 sensor would then be about 33mp.
