OM System M.Zuiko Digital ED 12-40mm f/2.8 PRO II

The definitive standard zoom for Micro Four Thirds — covering a versatile 24–80mm equivalent range at a constant f/2.8 aperture. Weather-sealed to -10°C, optically excellent corner to corner, and compact enough to carry all day. A perfect match for the OM-1 series and all Lumix G cameras.

GearFrame's Take

The go-to standard zoom for Micro Four Thirds — sharp, fast, and built to withstand the elements.
