Good old PMA. Always full of camera announcements to keep the wheels of commerce rolling along. Go commerce!

First up we have the Pentax K20D. It’s similar to the Pentax K10D, with such upgrades as a 14.6 megapixel sensor manufactured by Samsung, live view, and an expanded dynamic range function. They say that the new sensor, while the same size as their competitors’ 12 megapixel sensors, has less circuitry around the edges, and therefore larger light-sensitive areas that let them get away with a higher resolution without more noise. It’ll be interesting to see what the tests turn up when K20D reviews start to come in. It fits in the midrange of DSLR models, above the also-new Pentax K200D, their entry-level model. The K200D is an update to the K100D, getting a resolution upgrade to 10.2 megapixels. It also features a weather-sealed body, and a CCD-based anti-shake system.

Also recently announced is the Samsung GX-20, which uses the same sensor as the Pentax K20D. And is all-around very similar; the body could easily be confused for a K20D body, and the resolution and main features are all the same. It sounds like Samsung has their own firmware, and they say they have different JPEG processing than the Pentax, but presumably the RAW files would be pretty indistinguishable between the GX-20 and K20D.

Pentax also announced a handful of new lenses: a 200mm f/2.8, 300mm f/4, 35mm f/2.8 macro, 18-55mm f/3.5-5.6, and a 55-300 f/4-5.8.
