Ricoh has created the GXR interchangeable unit, a small, lightweight SLR camera. Unlike other mirrorless cameras, the GXR combines the lens, image sensor and processing engines into a single, detachable unit.

Packaging the lens allows each unit to be fitted with its own sensor size and processing capabilities, essentially rendering a new camera with every lens. With the GXR, the body simply houses the controls, screen and card slots. Only 4.5 by 2.75 by 1.1 inches in size and less than...

Samsung has released a new line of cameras, the NX10 — a compact, mirrorless product with 14.6-megapixel resolution, a larger APS-C sensor, a brighter AMOLED screen and faster autofocus.

The APS-C mirrorless sensor is 1.5 times as large as a traditional 4:3 sensor, and it reduces the size of the camera by 15 percent to 87 x 123mm. The improved, 3-inch AMOLED screen now allows users to view images on the monitor at any angle and in any lighting condition, including acute angles and bright sunlight. A new autofocus DRIMe II Pro engine allows for...

Olympus has developed an even smaller-bodied model of its micro four-thirds camera, the EP-2 — a 12.3-megapixel interchangeable-lens camera with an enhanced continuous autofocus tracking system, two new art filers and additional connectivity ports. C-AF Tracking and AF Target registration allow users to lock onto subjects and adjust exposure and focus.

New to this camera, the diorama art filter creates a "miniature model" with narrow depth of focus and enhanced subject contrast. The cross-process art filter easily manipulates...

Nikon has released its FX-format D3S, a pro SLR camera with a 12.1-megapixel FX-format CMOS sensor. The new camera has 51 autofocus points, an extremely broad ISO range and can capture up to 9 fps in the FX-format or 11 fps in the DX crop mode.

The D3S contains a multi-CAM 3500FX focus module, with 51 AF points, 15 cross-type sensors and 36 horizontal sensors that lock onto moving subjects. AF comes in three modes — single point, dynamic area and...
