Panasonic LUMIX G VARIO 12-60mm f/3.5-5.6 ASPH. POWER O.I.S. Review

Panasonic LUMIX G VARIO 12-60mm f/3.5-5.6 ASPH. POWER O.I.S. Sharpness at 40mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The LUMIX G VARIO 7-40mm F2.8 ASPH lens was attached to a Panasonic Lumix DMC-GX7 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 centre is a little soft wide open, with peak performance achieved in the f/8-f/11 range. Diffraction sets in at around f/16 with its effects becoming much more visible at f/22.

The edges are somewhat soft at f/5.4, but sharpen up very nicely at f/8, which is the optimum setting.
