Images from the Olympus lens are visibly softer than the others in the group test, and it's especially noticeable when it's at 54mm.

Fringing test

At 14mm, red fringing is visible at the very edges of the frame, but as the focal length increases the influence drops off.

Distortion test

Distortion performance is good, with mild barrelling at 14mm. The 2x crop factor of the Four Thirds sensor means wide angles are required.

Image test verdict

Throughout the focal range sharpness is low, but there's only a little softening towards the edges. Fringing and distortion results are good.

Score: 3/5
