Here we look at relative image quality between the Panasonic Lumix GH3 and the Olympus E-M5. The Olympus E-M5 has a reputation for very high quality. The Panasonic GH3 can also be expected to be good, but seems to have had a lot of attention to video usage, which might affect certain performance characteristics for stills, such as an anti-aliasing filter.
Shooting the comparison
The superlative Olympus SHG 35-100mm f/2 ED was used at its 55mm zoom setting, along with the required MMF-3 adapter and a B+W 81A warming filter. It doesn’t get any better optically than the SHG 35-100mm f/2 ED.
The lens choice allowed the lens to remain in absolutely the same position, switching out the camera thus eliminating camera mounting and height differences. The right idea, but Murphy’s Law intervened: there is still a difference in framing— the GH3 does not mount the lens in exactly the same rotation as the E-M5, the GH3 has a little more slop in the rotation. Both cameras have a slight back and forth “tick” in the lens-to-camera interface, but the GH3 has more.
