Pentax Optio WG-2 Digital Camera Review$399.95
Low Light Performance
The WG-2 is not a good low-light camera. Mid and high ISO performance is poor, and the lens starts at a mediocre f/3.5. If you want to attempt low-light shots, you'll need to crank up the sensitivity and deal with sloppy image quality, settle for blurry photos, or turn on the flash. In any case, this is not the camera you want if you take a lot of low-light photos.
Noise is a problem in the WG-2's photos. We measured more than 1 percent noise at the base ISO setting (125)—not something we usually see until ISO 800 on most compact cameras. The ratio stays pretty consistent through ISO 1600, but in this case, that's a bad thing. That means the noise reduction is aggressive throughout the entire ISO range, scrubbing away fine details from any shot in any kind of lighting. It's acceptable through ISO 400, but too sloppy at any higher settings. More on how we test noise.
Full-resolution photos can be taken at ISOs 125 through 6400 (adjustable in full stops). An auto ISO setting is available with an adjustable maximum, from 200 to 6400.
Video: Low Light Sensitivity
Low light sensitivity also surprised us, only dropping below our acceptable threshold at 8 lux—it's not uncommon to see point-and-shoots fail to pass 30 lux.
