Panasonic Lumix DMC-LX7 review - Expert Compact: Panasonic is back in competitionBy Kevin Carter - Monday February 18 2013 Sensor Review
The predecessor of the LX7, the CCD-equipped version, the LX5, achieved a DxOMark score of 41 and is currently ranked 178th globally in our database. So the DxOMark Score of 50 for the new LX7 indicates some improvements in sensor capability. Overall with a DxOMark Score of 50 the LX7 means it is ranked 173rd against cameras of all formats, and comes 9th out of the compacts tested (at the time of writing).
Of those smaller sensor compact cameras, it ranks 7th in our Portrait use case test with a Color Depth of 20.7 bits (up from 19.6 bits for the LX5). While on the low-side (22 bits is considered excellent), this is a good score and plenty sufficient to provide nuanced color discrimination at base ISO.
Panasonic hasn’t fared well in Dynamic range measurements previously, however, in the Landscape test, the LX7 scores highly with a very impressive Dynamic Range of 11.7 Evs (at base ISO). This is higher the firm’s larger size 4:3 sensor in the Lumix G-series cameras, though this wouldn’t be noticeable in real world use. Nevertheless, this is almost 1Ev extra exposure range over the LX5 and places the LX7 5th in Dynamic range out of the compacts in our database.
Up to now the new sensor has performed admirably but the LX7 falls down in the low-light category coming 23rd in the compact camera category (and 191 overall in our Low Light scores). The Low-light ISO score (just 147 ISO) is a bit low when compared with its main rivals but the result actually shows an improvement over its predecessor when set at high ISO (ISO1600 and above).
