Olympus PEN Lite (E-PL7) sensor review: Solid perfomerBy Kevin Carter - Wednesday February 04 2015 Sensor Review
Achieving a DxOMark score of 72 points, the sensor in the E-PL7 ranks in 97th place in the DxOMark database for all sensor formats and in 7th place overall for the Micro-Four-Thirds format. This is just 2 points lower than the best in class, the Panasonic Lumix GH4 with a score of 74 points, and only 1 point behind the maker’s OM-D E-M1, meaning that sensor performance is practically identical.
Measured at 22.7 bits, color sensitivity is on par with those models, as is the dynamic range of 12.5 EVs (the E-M1 has slightly better DR throughout the ISO range) and the low-light ISO score (873). This sensor is about as good as it gets for this format currently, and if you’re looking for better sensor performance, then you will have to move to an APS-C. Models such as the Sony A5100 can deliver slightly improved color discrimination, a little wider dynamic range, and better low-light performance (but remember that there may be other trade-offs to consider — we’re limiting this discussion to sensor performance).
