Resolution Chart Comparison (Raw)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. For a (more) level playing field we also convert our resolution tests using Adobe Camera RAW. Because Adobe Camera RAW applies different levels of sharpening to different cameras (this confirmed) we had to use the following workflow for these conversions:
Please not that for this comparison we converted the E-P1 RAW files in Capture One (using the default settings). This is because we have reason to believe that Adobe Camera Raw doesn't show the full resolution captured by recent Olympus SLRs (Capture One shows visibly more detail).
Measurable results
All of the cameras in this comparison show a significant resolution boost in shooting raw, but the X1 the most of all, eliminating any significant difference between it and the D300S. It's pretty clear that if you want to get the best out of the X1, you're really going to have to work in raw. |
