After last night's launch of Pentax's replacement for the K10D it comes as no surprise to see Samsung unveiling its own version in the shape of the GX-20. Essentially it's the same camera with a very slightly different body design, different menus and - according to Samsung - it's own JPEG processing. Key changes are identical to the Pentax; 14.6 megapixel CMOS sensor (jointly developed, manufactured by Samsung), live view and a larger 2.7 inch LCD.
