Lens review

Olympus Zuiko Digital 9-18 mm f/4-5.6 ED

5. Chromatic aberration

ZD 9-18 mm should be very praised for the CA correction level. Once again, these are one of the best results among the ultra-wideangle lenses.

What’s more, ZD 9-18 mm fares even better than its Olympus competitors. It’s enough to remind that ZD 11-22 mm’s aberration was high at the widest angle (0.17% at maximum aperture) and medium in the mid range. ZD 9-18 mm’ aberration is medium or low almost everywhere apart from the wide angle maximum aperture, where its value reaches 0.13% - close to the border between high and medium levels.
