Resolution Chart Comparison

Shots here are of our new '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 +0.7 EV to +1.3 EV (depending on the camera).

Measurable findings (three measurements taken for each camera):

As expected the D80 delivered the same 2200/1800 LPH performance we saw from the DSLR-A100, the only clear difference being that both the D80 and EOS 400D blur detail beyond 2300 LPH where as the DSLR-A100 appears to continue it, along with some moire. Is it a big step from eight megapixels? No, but then Nikon didn't do eight megapixels.
