Quote:Nikon D7200 sensor size: 23.5mm wide. Olympus OM-D E-M10 sensor size: 17.3mm wide.
23.5 / 17.3 = 1.3584
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:
- EM10: sqrt(17.3^2 + 13^2) = approx. 21.64
- D7200: sqrt(23.5^2 + 15.6^2) = approx. 28.21
