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 set to deliver approximately 80% luminance of white area.

I bought this oldie digital as a first experience vith digital cameras, even still use film mainly. So may it was a wrong decision, but I stay beside classic film photography. This camera slow, cheap and only manual mode able to firing promptly. I missed such a moments just because it wait so much before release the shutter. The lens as it is, so far from my zeiss with contax 35mm. Obviously nonsense to compare 66 rolleiflex images. There are lots of set up features, but practically takes long time to modify them, which disturb so much the picture taking. The CF card door a slim plastic door, very fragile. The viewfinder very small. All around this model are far away any real reflex cameras, it seems who design it just never take pictures with a proper camera. I can not recommend this camera, better to smash them all in the name of photography.
