Panasonic Leica DG Summilux 12mm f/1.4 ASPH Review

June 15, 2016 | Mark Goldstein |

Sharpness at 12mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Panasonic Leica DG Summilux 12mm f/1.4 ASPH lens was attached to a Panasonic Lumix DMC-GX80 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.

Both centre and edge sharpness is respectable even wide open at f/1.4, sharpening up nicely by f/2, with some fall-off in performance from f/11 onwards due to diffraction.
