Studio Comparison

Our latest test scene is designed to simulate both daylight and low-light shooting. Pressing the 'lighting' buttons at the top of the widget allows you to switch between the two. The daylight scene is shot with manually set white balance, but the camera is left in its Auto setting for the low-light tests.

The Olympus E-P5 is a peer to the GM1, carrying the same impressive 16MP sensor as the Olympus OM-D E-M5. Through ISO 400 the GM1 does a good job keeping up with it in terms of resolution. However, the E-P5's JPEG color rendition is a bit nicer, especially given the GM1's tendency to give a greenish tint to yellows. It's correctable in Raw, of course.

Moving up to ISO 6400 shows the GM1 struggling with noise suppression, leaving a good deal of digital artifacts where the E-P5 chooses to smooth more of it out. ISO 25600, the very highest setting, is more of the same. So it seems the GM1 does an admirable job keeping up with arguably the best in its sensor size class, but will require more post-processing to get the best results. Comparing to a step-up sensor like that of the Fujifilm X-M1 shows them to be evenly matched at low ISO though the APS-C mirrorless camera has a slight advantage in resolution as ISO increases.

For another interesting comparison, take a look at the GM1 head-to-head against some of its closest competitors in terms of size. The Nikon 1 S1 and Pentax Q7 both use smaller sensors and accordingly, are outperformed by the GM1 in terms of resolution and noise. The Sony NEX-3N, however, uses an APS-C sensor and should have a slight edge over the MFT Panasonic camera as ISO rises. Our studio test scene shows them to be closely matched at low ISOs and interestingly, the GM1 has a slight edge at ISO 6400. Panasonic's typically Panasonic image processing leaves a good deal of color noise which in comparison don't look as pleasant, but some fine detail is preserved. However, switching to Raw shows the NEX-3N with slightly more noise. It's not a drastic difference though, and processing Raw files from either would yield similar results.
