Lighting was a worst-case single 100W tungsten bulb high and to the right of the scene. Focusing was manual with the crop area as the focus target. All ISO sequences were shot in Aperture Priority with a fixed aperture of f/4.0. To eliminate variations in lens quality as much as possible, all images were photographed using the manufacturers 50mm f/1.4 normal lens. Therefore, any field of view variations are a result of the different sensors and multipliers for each camera. In all images the tripod is mounted in the same location relative to the scene being photographed. However, you can view the full-size images by clicking on the crops and the field of view is the same among 1.6x sensors since the crop factor, sensor multiplier, and shooting position is the same. This is because there are more pixels in the image area. On 14.2 and 12.2MP sensors the crop area represents a smaller (more enlarged) portion of the scene than on the 10.1MP crops.

Since the crops represent actual image pixels, the covered area for the crop varies with the resolution changes. The Canon XSi is a 1.6x sensor so the coverage is slightly less than the 1.5X sensors at the same resolution. The crop area on the 1.5X multiplier Sony and Nikon are represented by the red rectangle on the full image above. All crops represent a view of 230x300 actual pixels cropped from the larger 12.2, 10.1, or 14.2MP images.
