Sharpness at 25mm
For these tests, the Olympus 12-50mm f3.5-6.3 lens was attached to an Olympus E-P3 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.

Centre sharpness is best at f/5.6-f/8. For the corners, the sweet spot of sharpness is f/8.
