Sharpness Cont... 4

Sharpness at 100mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The LUMIX G VARIO 35-100mm F2.8 ASPH lens was attached to a Panasonic Lumix DMC-GF5 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 100mm

Centre sharpness at 100mm is outstanding even wide-open at f/2.8, while the edges are acceptably sharp from f/5.6 to f/16.
