SD1 - NEX 7 - T3i - GH2 - V1 Resolution Test

Here is a comparison of resolution tests conducted by http://www.imaging-resource.com between the Sigma SD1, Sony NEX 7, Canon T3i, Panasonic GH2 and the Nikon V1.

I have included the image of a blue and red colour resolution wheel as it is the most taxing on a Bayer sensor due to only 1/4 of the pixels being either red or blue hence the jagged diagonal edges displayed.

The images have not been scaled and are at 100% resolution. The images have only been cropped.

I have placed the photos in order of sensor size

Nikon V1 - CX format (13.2 x 8.8 mm)
Panasonic GH2 - Four Thirds (17.3 x 13 mm)
Canon T3i - APS-C (22.3 x 14.9 mm)
Sony NEX 7 - APS-C (23.5 x 15.6 mm)
Sigma SD1 - APS-C (24 x 16 mm)
