Sharpness at 200mm

For this test, the Panasonic Lumix S 100-500mm F5-7.1 O.I.S. lens was attached to a Panasonic Lumix S5 II 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 200mm

Centre sharpness is outstanding from wide-open at f/6.1 all the way through to f/16, with f/22 being slightly affected by diffraction.

The edges are nearly as sharp as the centre, with the best results again obtained from f/6.1 through to f/16.
