ResolutionNoise
Noise was low across the ISO range, but noise reduction leads to some loss of detail at higher ISOs.
Noise (9.08)
Noise is the Achilles heel of digital cameras: the electronics that capture the image produce a small amount of electrical noise as they work, which shows up in the image as a grainy pattern that hides the details. This noise gets increased as the camera boosts the ISO sensitivity to make more use of the light. which is why your low-light images look grainier than the daylight ones. We didn’t find that noise was a huge problem on this camera, though: it was present at all ISO levels, but didn’t become a problem until the ISO was increased above 800. More on how we test noise.
We run our tests shooting with the EX-G1 at two different light levels: 3000 lux (about what you would get on a cloudy day outdoors) and 60 lux (indoor lighting). The noise levels remain pretty close in both tests, climbing above 2 percent at ISO 1600.

In the chart below, we compare the noise levels of this camera with others. As you can see, the EX-G1 did a pretty impressive job here: we found that the noise level remained lower than most cameras across the ISO range.
ISO (5.50)
The EX-G1 supports a wide ISO range of 64 to 3200, all at the full resolution of the camera. That’s unusual; most point & shoot cameras only offer 3200 as an option with reduced resolution. Mind you, as the samples images below show, the image is extremely noisy at the higher settings, so they should only be used when absolutely required. Below are examples of photos taken at all of the ISO levels supported by the EX-G1 and all of our comparison cameras.
