Olympus M.ZUIKO Digital ED 14-42mm f3.5-5.6 EZ Review

Sharpness at 14mm

For these tests, the Olympus M.ZUIKO Digital ED 14-42mm f3.5-5.6 EZ lens was attached to an Olympus OM-D E-M10 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.

Centre sharpness is pretty high even wide open at f/3.5, with peak performance achieved at f/8. Diffraction kicks in at f/16 and f/22.

The corners aren't as sharp as the centre, and not until f/5.6. For a relatively OK performance, shoot at f/5.6-f/8.
