Pentax K-30 Digital Camera Review
The Pentax K-30 offers four levels of noise reduction, as well as the ability to turn it off. The four levels include low, medium, high, as well as an automatic feature. The automatic setting returned noise results similar to the "low" and "off" settings, moving up to about a medium level at ISO 6400 and above. More on how we test noise.
The Pentax K-30 offers an ISO range of 100-12800, with the option to set ISO manually or automatically. You can also extend the ISO up to 25600, but you have to go into the custom menu to activate that first.
Focus was a bit of a hang-up performance issue on the Pentax K-5, as it could really struggle under low light conditions. We found that indoor artificial lighting, especially. The camera would lock on, but it often took more than few seconds, even when using fast primes like the Pentax 35mm f/2.4, as we did in our time with the K-5. The K-30 is designed with a new autofocus system, but we put it to the test in low light to see if it offered much improvement.
Video: Low Light Sensitivity
The Pentax K-30 required only 11 lux to render an image that hit 50 IRE on a waveform monitor in our testing. 50 IRE is a standard for what is considered visually acceptable. That puts the Pentax among the middle of the pack as far as DSLRs are concerned. The K-30 gets that low as it's able to use up to ISO 3200 when recording video, while the cameras that perform better in this test have a wider range of ISO speeds to call upon.
