Sharpness

Sharpness at 8mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The LUMIX G FISHEYE 8mm F3.5 lens was attached to a Panasonic Lumix DMC-GH2 compact system camera, which in turn was mounted on a sturdy tripod. The self-timer was used to avoid any vibrations from pressing the shutter release. Slight tonal changes are due to slight changes in natural light during the session.

The full frame at 8mm

Centre sharpness is perfectly acceptable from f/3.5 to f/11, while the edges are sharp enough from f/4 to f/11.
