Samsung are showcasing their 14 megapixel GX20 DSLR, successor to the GX10 and close sibling to the Pentax K20D (they're basically the same camera). Note that in the UK the GX20 is some £200 cheaper than Pentax's version. As with every other manufactuer at PMA 2008, Samsung also have a multitude of new compacts on show. I've now tracked down the Samsung GX20 wireless grip, which is being shown in early prototype form. This slots into the bottom of the camera and provides Wi-Fi connectivity. The prototype doesn't have room for batteries, but the final version may take batteries when it's released around May.
