Panasonic Lumix S 18mm F1.8 Review

Sharpness at 18mm
For this test, the Panasonic Lumix S 18mm F1.8 lens was attached to a Panasonic Lumix S1R body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.

Centre sharpness is very good wide-open at f/1.8, and outstanding from f/2.8 all the way through to f/11, with f/16 being adversely affected by diffraction.
The edges aren't quite as sharp as the centre, with f/5.6 to f/11 producing the sharpest results.
