Sharpness at 40mm
For this test, the Panasonic Lumix S 18-40mm F4.5-6.3 lens was attached to a Panasonic Lumix S5II 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.
The full frame at 40mm
The centre is a little soft wide open at f/6.3, with peak performance achieved in the f/8-f/11 range. Diffraction starts to set in at f/16.
The edges are almost as sharp as the centre, with f/8 to f/11 again being the optimum settings.
