Product Overview
OM System / Olympus M.Zuiko 12-40mm F2.8 PRO II is a standard zoom lens for Micro Four Thirds-mount. It covers the MFT image circle. Introduced by Olympus in 2022, it has 14 elements in 9 groups.
Like most zoom lenses, the OM System 12-40mm F2.8 PRO II is externally-zooming. For incremental weathers, Olympus is kind enough to include weather sealing.
A standard zoom lens with relatively bright maximum aperture, the OM System 12-40mm F2.8 PRO II can be a key piece in a photographer's arsenal, though some may prefer prime lenses in this focal range.
Compared to the Mark I lens, this new model has suspiciously the same dimensions and weight. One wonders what OM System / Olympus has changed to justify the price increase.
