We use Imatest and DxO Analyzer hardware and software to test cameras for their colour accuracy (colour error) signal to noise ratio (the amount of noise in the images) and dynamic range (their ability to capture detail in very bright and dark areas). We also pick three rival cameras to test them against.
It’s not the worst, it’s not the best. The OM-D E-M1 II’s colour rendition is more accurate than the X-T2’s, but the Sony A6300 and Panasonic GH4 are more neutral.
Signal to noise ratio
The Olympus doesn’t achieve the same performance as the X-T2 or, surprisingly, the rather good GH4. It did better than the Sony A6300 at higher ISOs, though.
The Panasonic GH4 and Sony A6300 are the winners here, but the Olympus is not so far behind and maintains its dynamic range right through to higher ISO settings.
