Our Exposure Latitude test delves into the deep shadows of base ISO images to test the degree to which you can underexpose to protect highlights, then exploit the camera’s full dynamic range. The GH6 is showing significantly more noise when given the same exposure as the OM-1. In principle this represents deeper shadows because of the difference in their respective base ISOs, but the difference is pronounced enough that you can comfortably conclude that the GH6 has less usable dynamic range than the OM-1.

The ISO invariance tells a similar story: above ISO 800, where the GH6’s Dual Output Gain system kicks in, the two camera look very similar, but push the lower ISOs and the Panasonic shows increasing noise levels in the very deep shadows. This suggests you should probably raise the ISO on the Panasonic, when shooting in low light, at least until you get to ISO 800. Above that point, you can keep ISO pinned at 800, underexpose and brighten in post, if you want to include extra highlights in your image.

The GH6’s dual output gain is one of the few times where there might be a significant change in dynamic range in the highlights. However, unlike in video mode, we’re not seeing an extra stop of highlight capture in the stills we’ve shot, so it could be that stills mode is set up differently, to give a shadow benefit instead of additional highlights. We’ll look more closely at this as we shoot more with the camera.
