Lens review

Olympus Zuiko Digital 25 mm f/2.8

5. Chromatic aberration

The ZD 2.8/25 chromatic aberration graph is simply the same as the significantly more expensive Leica’s. At maximum relative aperture the number of problems is the lowest because there that aberration’s value reaches the borderline between the low and medium level. The aberration increases on stopping down but never exceeds the medium values.

If we are interested in a lens with a similar focal length but almost without aberration, we should look no further than the Olympus 3.5/35. It clearly wins in this category, distancing its competitors by far.
