To measure and compare the Sony Cyber-shot N2’s corner sharpness we photographed the Enhanced Digital Camera Resolution Chart with it and a number of rival models, each using their best quality JPEG and default image tone and sharpening settings. We used the built-in lenses at their widest and longest focal lengths and with various apertures starting from fully open. Note the Panasonic TZ1 and Sony N2 only offer two and three apertures respectively at each focal length, so all are shown in this test. The crops are taken from the extreme lower left corner of the chart and presented here at 100%. |
Zoomed-out to wide angle, the Sony N2 crops from the extreme corners reveal a little coloured fringing at all apertures and some softness when the aperture’s wide open. The results aren’t bad, but the other cameras below delivered better-looking corner performance. Zoom-into telephoto and the N2’s corners again suffer from coloured fringing, especially compared to the Canon A640 and Fujifilm F30 results. As before, there’s also slight softening with the aperture wide open. To be fair we’ve seen much worse, but the N2 is shown-up here against some particularly good results alongside. Note: crop details which appear smaller here are due to them being captured with lower resolution cameras and / or a lens which couldn’t focus as close to the chart. In each case though, the crop still represents the extreme left corner of each camera’s frame. |
