The Samsung GX-20 SLR Digital Camera combines comprehensive functions, stunning design and ease of use in a durable camera body. With a 14.6 megapixel image sensor, the GX-20 produces sharp images with rich colors and greater dynamic range. The camera can capture both JPEG & RAW File formats and it is equipped with a one-touch RAW button that makes it easy to capture a RAW image of that special scene, even if the camera is set to capture in the JPEG format.
Additionally, RAW files can be directly converted to the more universal JPEG format right in the camera via the built-in converter. The GX-20 is also fast - providing continuous shooting at 3 fps so users will always get that great action shot. The Samsung GX-20 is compatible with Samsung's own lenses and is also compatible with all Pentax lenses (the camera uses the Pentax KAF2 bayonet mount). Furthermore, with its powerful built-in Optical Picture Stabilization (OPS) technology, the GX-20 prevents blurred pictures by shifting the CCD to counter any movement of the camera's body and ensures sharper images - even in low light with slower shutter speeds.
And since the system is built into the body - you'll get the benefits of the OPS system with any compatible lens - there is no need to purchase special anti-shake lenses. The GX-20 has a wide view 2.7" TFT Color LCD Display that provides a Live View feature which provides for easier shooting from odd angles that would be difficult to shoot from, using the optical viewfinder.
The camera body is also water & dust-resistant so that you can shoot under most conditions and the advanced Dual Dust Removal System built into the GX-20 removes problematic particles from the sensor, resulting in perfect, blemish-free pictures with minimum effort on the part of the photographer.
