24 January 2008 – Samsung, leaders in digital imaging, today announces the launch of the 14.6 mega-pixel GX-20 digital SLR. The Samsung GX-20 is aimed firmly at the discerning enthusiast photographer who wants comprehensive functions, stunning design, ease of use and real value for money - all in one camera. Samsung also announces the launch of two new lenses, giving both GX-20 and GX-10 series users even more freedom to express their creativity.
Robert King, Commercial Director of Samsung Cameras says, “With the launch of the GX-20 digital SLR, Samsung has a full digital camera line-up ranging from convergent compact digital cameras through to high-end fully-featured digital SLRs. This product is the start of an exciting DSLR range for Samsung as it is our first DSLR with our own manufactured CMOS sensor. This is a very important step for Samsung which is set to support our expansion in this competitive product sector.
“The GX-10 is the next step in Samsung's continued growth in the SLR market – the new GX-20 offers cutting-edge functions as well as outstanding picture quality to satisfy users of all abilities.”
GX-20 - Intelligent design
The GX20 boasts a 14.6 mega-pixel image sensor, which offers the photographer a sharper image with richer colours for a truly compelling composition. Taking photos is made easier with the Enhanced Digital Filter which allows a greater dynamic range of exposures and can also be used to add various effects or compensate for missing pixels after taking a picture. For unrivalled photo viewing, the GX-20 also comes complete with a wide view 2.7” TFT LCD (230k pixels) and live view through the optical viewfinder or LCD display.
With its powerful built-in Optical Picture Stabilisation (OPS) technology, the GX-20 prevents blurred pictures by shifting the CCD to counter any movement of the camera’s body. This function is designed to minimize shake by oscillating the image sensor vertically and horizontally – eliminating the need for additional anti-shake lenses.
The GX-20 is robust enough for taking quality pictures in wet, sandy or dusty conditions. The special water-resistant and anti-dusting body sealing protects 72 different parts and the advanced Dual Dust Removal System included in the GX-20 also removes problematic particles from the sensor, resulting in perfect, blemish-free pictures with minimum effort on the part of the photographer.
With the one-touch RAW button, built into the GX-20, RAW file shooting is made simple and instantly available to users even during general JPEG shooting. The RAW files can be checked on the LCD and then be directly converted to JPEG format via the built-in converter.
With the GX-20, continuous shooting at 3 fps (frames per second) is possible; up to 9 fps; giving the user the best chance to get a great picture.
A comprehensive lens offering
Samsung also announces the launch of two new lenses. These lenses have been designed to enable real freedom in the creative process and include: 18-55mm II F3.5~F5.6 and 18-250mm F3.5~F6.3. The lenses are also compatible with Samsung’s popular GX-10 DSLR.
The award winning i range and NV series (including EISA and TIPA awards) launched in 2007, have enabled Samsung to grow consistently and take market share in the compact camera space. The launch of the GX-20 will see Samsung building on the success of the GX-10 and increase its presence in the digital SLR market.

The GX-20 is Samsung's fourth digital SLR produced in association with Pentax, and - slight styling and menu differences aside - is essentially the same camera as the Pentax K20D launched last night. Although pricing is obviously fairly fluid in this market the GX-20 is expected to sell for slightly less than the K20D. There's not a huge amount to say about the GX-20 that doesn't apply to the K20D, so we'll mainly stick to looking at the differences on this page.
As with the K20D this is a case of 'evolution' rather than 'revolution' compared to the GX-10 (which was a Pentax K10D doppleganger). The key changes are the new higher resolution sensor and, this being 2008, Live Preview.
|There are small exteral differences between the GX-20 and the K20D, but it's obvious that the cameras share the same DNA.|
In fact the only differences between the K20D and the GX-20 are the menu layout and user-interface (where, on first impressions at least, Samsung actually appears to be the better of the two), the supplied RAW converter and the design of the buttons and body shape (the buttons are all in the same place and have the same functions). There may well be minor feature differences (Samsung's spec and press release are rather thin on detail) that we missed in the few hours we spent with the GX-20; we'll document these in depth when we get to the reviewing stage.
The new CMOS sensor (15.1 MP, 14.6 million effective pixels) is manufactured by Samsung but co-developed with Pentax and gives sensitivity settings of ISO 100-3200 (ISO 6400 is also available as a custom function). We're told that the internal (JPEG) processing is different on the two cameras, though how this will affect the end result will have to wait until we've had chance to test the cameras side-by-side.
Like the K20D (and the K10D / GX-10) the GX-20 feels solidly built and fits the hand very comfortably with all the important controls in the right place and a large grip. The grip is actually slightly different on the GX-20 and the K20D, and which you prefer will be a matter of taste (and possibly the size of your hands).
