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. Throughthe 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 It's correctable in .
Moving up to ISO 6400 shows the GM1 struggling with noise suppression, leaving awhere the E-P5 chooses to smooth more of it out. , 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 though the APS-C mirrorless camera has a slight advantage in resolution .
For another interesting comparison, take a look at the GM1 head-to-head against some of its closest competitors in terms of size. Theand both use smaller sensors and accordingly, are outperformed by the GM1 in terms of resolution and noise. The , 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 and interestingly, the GM1 has a slight edge 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 It's not a drastic difference though, and processing Raw files from either would yield similar results.
