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.
The full frame at 14mm
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.
