Additional features and details adapted from the Samsug GX-20 Press Release:

The GX-20 improves on many of the advanced qualities of its sibling dSLR, the 10.2 mega-pixel GX-10; however a host of new features and firsts truly set this camera apart from any other GX-Series model previously introduced by Samsung. The GX-20 is highlighted by its proprietary, high-performance CMOS sensor. The Samsung CMOS sensor is equipped with 14 mega-pixel resolution, can capture 14-bit Raw images and maintains outstanding noise performance, even at a high ISO setting of 6400. The GX-20 also incorporates improved sensor-based shake-reduction as well as a double dust-removal system, which is designed to prevent miniscule specs of dust from ruining a perfect image.

Designed for the advanced amateur and professional photographer, the GX-20 is the fourth model in Samsung's rapidly growing dSLR range. The premier model of the GX family, Samsung's new GX-20 takes performance to a whole new level with an array of new and improved features, all which will allow users to capture images of uncompromising quality in any environment or setting. Photographers of all skill levels will appreciate the GX-20's large 2.7 inch Live View LCD screen, which allows users to check composition and focus directly on the LCD in real time.

The GX-20's improved sensor-based shake reduction system, dubbed Optical Image Stabilization, helps photographers overcome the detrimental effects of hand shake and helps minimize blur in situations where the camera is unstable or in low-light conditions. Because it resides in the camera body, as opposed to the lens, the OPS feature works with a wide range of lenses, including Samsung's Schneider D-XENON family and the full range of Pentax, KAF2, KAF and KA mount lenses.

Additionally, the GX-20 features a Pentaprism viewfinder that yields a 95 percent wide field of view and provides photographers with a bright and accurate view of their subject, allowing them to properly frame and fine-tune out-of-focus areas. Furthermore, with a maximum shutter speed of 1/4000 second, shooters can rest assured that they'll never miss the perfect shot, especially when it comes to fast-moving events.

The GX-20's revolutionary new double dust-removal system is designed to prevent dust from threatening the quality of images captured with the GX-20. Samsung has incorporated an advanced dust-removal system that can be set to automatically vibrate the CMOS sensor when the GX-20 is powered on or engaged independently by the shooter and has also manufactured the GX-20's proprietary sensor with a special dust resistant coating, further eliminating the possibility of unwanted specs or blemishes ruining an otherwise perfect picture. As if that weren't enough, the GX-20 boasts a specially designed body that was made to stand up to the elements. Every button, gap and other potentially vulnerable area on the camera's body has been fortified with special seals and silicone to protect against damage from water, sand and a host of other elements

Another attractive feature for advanced photographers is the GX-20's superb Raw image format support. The exclusive one-touch Raw shooting button enables users to quickly capture 14-bit Raw images, which can then be quickly be viewed on the LCD screen. If the shooter desires, the Raw image can also be converted to JPEG format directly on the camera. The GX-20's intuitive and easy to use interface makes even the most advanced tasks easy to accomplish for just about anyone. The GX-20's continuous shooting mode is capable of capturing up to three pictures per second (pps). Depending on available memory, shooters can capture an unlimited number of JPEG images in continuous shooting mode and up to nine images in Raw format.

For accurate autofocusing in any shooting condition, shooters can take advantage of the GX-20's 11-point TTL, wide-area Auto Focus system. For added versatility and to compliment their shooting style, users have a choice of AF-single or AF-continuous. The GX-20 also features a TTL open-aperture 16-segment metering system for accurate exposures, as well as center-weighted and spot metering.
