Wide ISO range
Solid handling design
Poor noise performance
Some colors were VERY off
Introduction
Colors remained vivid and strong in low light. Noise levels were high, however, and low light sensitivity wasn’t very good.

Video: Low Light Sensitivity (0.97)
Testing the Pentax K-x with its kit lens, the camera didn’t do a very good job with low light sensitivity. Still, compared to some of the abysmal results we’ve gotten from other video-capable DSLRs, the K-x’s numbers don’t look too bad. The K-x required 23 lux of light to register 50 IRE on our waveform monitor. Of the DSLRs we compared it to below, only the Nikon D5000 had a better low light sensitivity (the Panasonic GF1 and Canon T1i were just slightly worse than the K-x). More on how CamcorderInfo tests low light sensitivity.
Of course, much of a camera’s low light sensitivity score comes down to what kind of lens you are using. The kit lens on the K-x is an f/3.5 18-55mm lens, so it isn’t that fast. If you shoot video with a lens that has faster aperture settings, you’re likely to get better low light sensitivity in video mode on the K-x.
