Camera Test: Pentax K20D

With rich features, a big 14.6MP sensor, and an estimated street price of $1,299, Pentax's super DSLR is a rare talent.

The 10.2MP Pentax K10D was a DSLR bargain in 2007 with its nearly pro body, excellent image quality, fast AF, image stabilization, and a price of only $920 (body only) when launched. It's still a steal at $700 (street). But if you want a camera with higher resolution, larger LCD, live view, and other enhancements, check out the new 14.6MP Pentax K20D ($1,299, estimated street).

At first, the K20D seems to be a twin to the K10D. Pentax kept what was outstanding in the K10D and improved it in all the right places, so the K20D is more of an upgrade than a new design. We got our hands on one of the first production units, and after running it through the Pop Photo Lab and field tests, found five reasons why this camera promises to be a big hit.

Image quality

This camera captures the most detail in its price class at ISOs below 1600. Incorporating the first Samsung-produced APS-C-sized CMOS sensor, the K20D represents a shift from the Sony CCDs found in previous Pentax DSLRs, and a further strengthening of Samsung's partnership with Pentax. By the time you read this, Samsung will have released its own camera with specs similar to the K20D.

According to Pentax, the new sensor captures 14.6 megapixels (effective) in 4672x3120-pixel files, with up to 12 bits per color in RAW. In addition, the pixel design expands the light-gathering photo diode to about the same area as competitive 12-megapixel CCD sensors. This gives the K20D the potential for higher resolution than the K10D, with light sensitivity similar to more expensive 12MP DSLRs such as the Nikon D300 ($1,800, street, body only) or Sony Alpha 700 ($1,350, street, body only). With increased sensitivity and noise reduction, Pentax boosted the normal ISO range up to ISO 3200, and the expanded range as high as ISO 6400.
