Quick Informal High ISO Image Comparison: Panasonic DMC-GH3 vs Olympus OM-D E-M5

Just as of this week, Panasonic has come out with it’s hotly awaited Panasonic GH-3. A camera with a cult following in video making. We decided to pit it against a highly respected competitor in the micro 4/3s category, the Olympus OM-D E-M5. Which camera had the cleaner image? Please let us know in the comments.

 

Gear Used

For this test we used the Olympus OMD EM5, Panasonic GH3 and the Voigtlander 17.5mm f0.95.

Process

Each cameras settings were mirrored. I shot the photos with the  Voigtländer f.95 wide open, at shutter speeds between 1/60 to 1/30. With ISOs at 800, 1600, 3200, 6400, 12800, 16000 and 25600. The white balance was changed to be the same color temperature in post-production. Images were cropped on the long side; 4000 pixels. That’s 608 pixels less than when it came out of the camera. No other alterations were made. Keeping the photos as raw as possible.

f.95 @ 1/30th ISO 12800

f.95 @ 1/30th ISO 16000

f.95 @ 1/30th ISO 25600

We later realized that the last image in the sequence was not matching the shutter speed of the OMD at ISO 25600. So we equalized this image with the one before it.
