Panasonic Lumix DMC-GH4 Samples

Crops below show the performance of the Panasonic Lumix DMC-GH4 next to the Fujifilm X-T1
Fujifilm X-T1, the flagship Fuji mirrorless which is also weather-sealed yet uses a larger 1.5X-Crop APS-C sensor.

All images below are 100% crops from their respective camera taken at the highest image quality JPEG setting available. ISO, aperture and white-balance were set on camera. As usual, cameras were calibrated to produce the best results they care capable of. These crops help determine which ISO settings are acceptable on these cameras. As noise increases, most cameras compensate with noise reduction which introduces softness and the point at which a print become unacceptably noisy is a matter of personal taste.

The Panasonic Lumix DMC-GH4 does very well in this series of indoor shots but its smaller sensor cannot keep up with the APS-C competition. The output, even with sharpness and noise-reduction at their optimum settings, produces soft output compared the the X-T1 which does not use an anti-alias filter.	ISO 51200
