Sharpness at 18mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Olympus M.ZUIKO 9-18mm f4-5.6 lens was attached to an Olympus E-P2 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. The 100% crops represent about 1/300th of the total frame area.
The full frame at 18mm
Centre sharpness is very good from f/5.6 through f/11, while the edges are sharpest at f/11.
