Pentax K20D DSLR Gets Official With 14.6 Megapixels, Live View and Expanded Dynamic Range

9:00AM January 24, 2008 | Matt Buchanan

Pentax’s long-rumoured US$1299 K20D is a shot square at Canon’s 40D and the
Nikon D300
. Besides price, it bests both in pure megapixel count—14.6 effective, with a new CMOS sensor developed with Samsung—and rocks the same top 3200 ISO (6400 expanded) as the D300. (Is it as impressively noiseless though?) Expanded Dynamic Range promises more contrast-y shots, plus image stabilisation is built into the camera’s body. Like the 40D and D300 it adds a live viewfinder, but it’s a bit tinier, 2.7 inches to their 3, with less than a third of the D300′s resolution, so the screen won’t be nearly as gorgeous. It comes up a little short against the competition in a couple of other ways, too.
Update: If you’re really drooling over the K20D, have a look at the new Pentax-produced walkthrough video below.

AU: Just got back from the Australian Pentax launch… local pricing will be $1,999 for the body plus an 18-55mm lens. Should be available now / very soon…


For one, its continuous shooting mode tops out at 3 FPS at full quality, half of either the 40D or D300. Also, unlike what was rumoured, its RAW A/D processor is only 12-bit, coming in a smidge below their 14-bit processors. Still, it looks like a solid camera for the price.

    There are 2 main points about the framerate that make it differ from the oposition
    (1) The framerate is continuous – 3FPS until the card is full, ie not slowing down after a few frames when the buffer is full.

    (2)The framerate is variable 3FPS at 14MP to 20 FPS at 1.6MP I know its only 1.6MP but 20FPS!!!!!

    Looks like a great camera. I only wish they improve the AF system later via firmware

    With its FX (Nikon’s designation for approx 35mm sized) CCD at 14.6 megapixels (MP), body-based Shake Reduction (SR), and anti-dust system, the K20D is more accurately described as a shot square at the more than 4X pricey Nikon D3 than it is at the comparatively priced D300, for which the nearly half-D300-cost K200D is tough competition. Like the K20D, Nikon’s D3 also preserves the lens coverage of 35mm film lenses, but at only 12.1 MP, the D3 surrenders a bit more than its very high price to the K20D. And, the K20D also takes Nikon by the throat by preserving one of Nikon’s most robust traits: lens compatibility throughout the previous-model/format line, even allowing those with the par-excellence SMC 645, medium-format, manual (MF) and AF lenses to put them to use on either the K20D or K200D (with adapter and some reduced functions—same with the Nikon D3/300 and MF AI/AIS non-CPU lenses). In this regard, the dashed hopes of those 645 owners for a 645D may be, in part, answered by the K20D, and may explain why Pentax ditched 645D development (if they really did) with an eye on the 645-lens-compatible K20D and its successors. In any circumstance, with its array of foundational features, and its $1300 price point, the K20D is a triumph nearly as satisfying as a common digital back for 645/645n/645nII bodies would be. Yet, with tens upon tens of thousands of those Pentax medium-format bodies and systems out there, and with the capability to put a man on the moon, why an affordable, common-645 digital back can’t be designed and produced escapes me.
