OM Digital Announces M.Zuiko 20mm f1.4 Pro Prime Share This on LinkedIn   Tweet This   Forward This

4 November 2021

OM Digital has announced the OM System M.Zuiko 20mm f1.4 Pro prime lens featuring a 40mm equivalent focal length for Micro Four Thirds cameras in a dust and splash proof design with a fast f1.4 aperture.

Lens construction uses a system of hermetic seals to lock out moisture, cold and dust. The fully-sealed splash, freeze and dustproof design not only protects the lens from harsh elements but maintains operation when the temperature dips down to down to -14°F.
