Olympus M.ZUIKO Digital ED 7-14mm f/2.8 PRO Review

June 5, 2015 | Mark Goldstein |

Sharpness at 14mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Olympus M.ZUIKO Digital ED 7-14mm f/2.8 PRO f4-5.6 lens was attached to an Olympus OM-D E-M5 Mk II 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.

Center sharpness is outstanding between f/4 and f/11. At f/16 and f/22 sharpness is beginning to drop off due to diffraction. The edges aren't quite so sharp, with the best results achieved by stopping down to f/5.6.
