Resolution Chart Comparison (JPEG)

Shots here are of our 'version two' resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation set to deliver approximately 80% luminance of white area.

Measurable results

The E-620's does a good job of eking out all the detail its sensor can capture - as we'll see on the next page, unlike the other cameras here, there's little resolution advantage to shooting RAW. It does a good job of staying competitive with the other cameras here, which is something that recent E-System Olympus cameras have struggled with.
