Simultaneously with the OM System OM-1 camera, OM Digital Solutions released two Micro Four Thirds system lenses. One of them is an updated version of the Olympus lens released in 2013. About him and will be discussed.
The M.Zuiko Digital ED 12-40mm F2.8 PRO II lens differs from its predecessor by improved sealing to meet the IP53 rating and a fluorine coating to prevent contamination of the front element. The manufacturer also claims that the addition of a ZERO (Zuiko Extra-low Reflection Optical) coating allowed better elimination of ghosting and flare and should improve image quality when shooting in backlight. The optical formula of the lens has not changed. Given the crop factor, this is a versatile lens covering one of the most sought-after focal length ranges.
