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 GF1 produces output that - unsurprisingly - is very similar to the G1 it is based on, and to the Olympus E-P1 (though the latter's better JPEG engine shows the same advantage here as it did in our studio still life tests). Overall the GF1 - even in JPEG mode - compares well to most entry level and mid range SLRs at a similar price point.
