Panasonic Lumix GH3 Digital Camera Review

Noise Reduction

The Panasonic GH3, like most cameras featuring smaller Micro Four Thirds sensors, produces a fair amount of noise at higher ISO levels. While the technology for these cameras is improving, it's not at the same level as cameras that feature full frame or APS-C image sensors, both of which allow for larger pixels that are more immune to the effects of image noise. As a result, the GH3 has to rely on software noise reduction in order to preserve detail without letting noise overpower the image, something the GH3 does quite successfully. More on how we test noise.
