Panasonic Leica DG Vario-Summilux 10-25mm F1.7 ASPH Review

Panasonic Leica DG Vario-Summilux 10-25mm F1.7 ASPH Sharpness at 14mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Panasonic Leica DG Vario-Summilux 10-25mm F1.7 ASPH lens was attached to a Panasonic Lumix G9 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 are excellent from f/1.7-f/8. Diffraction starts to affect the image sharpness from f/11 onwards.
