The Sigma DP3 Merrill is the latest Sigma camera with the new Foveon sensor. With this sensor, the camera can capture complete RGB information for every single pixel and doesn’t need to interpolate colors like all other digital cameras with Bayer pattern sensors. The APS-C sized sensor offers a resolution of 14.7MP, referred to by Sigma as equivalent to 45MP resolution of a standard sensor ((4704 x 3136 pixel x 3 RGB data per pixel).

The X20 uses an X-Trans sensor just like all new Fujifilm X cameras. Instead of an APS-C-sized system it’s a 2/3 inch sensor, which is slightly smaller than APS-C, but still very large for a compact camera. In combination with the moderate resolution of 12MP the camera offers very clean and noise-free images.

The EOS Rebel SL1 is an ultra-small SLR system; in fact it is smaller than many bridge cameras and even lighter than many other digital cameras.
Nevertheless it’s a real SLR system with Canon’s APS-C-sized image sensor, which is a little smaller than other APS-C-sized sensors made by Nikon, Sony and other manufacturers. Due to itsvery small body the grip on the right hand side is also is a bit smaller than usual and the handling of the camera is a bit tricky for photographers withlarge hands. The small body doesn’t allow for a status LCD on the top, so all information on image parameters and menu settings are shown on the LCD screen on the back.

Fujifilm’s X100s follows the X100 and offers enhanced imaging features and functions. The most important difference is the new sensor--the X-Trans CMOS sensor uses aspecial RGB mosaic pattern and offers higher resolution compared to the sensor in the X100. The new sensor has special mirco lenses that result in a very sharp and brilliant image, which is then enhanced further with the camera’s new EXR II image processor.
