Olympus has chosen this lens as their first release in the newly designated lineup of M. Zuiko Pro lenses. These are lenses with rugged weather-sealing. So rugged, in fact, that they are advertised as being dust-, splash-, and freezeproof, making them solid companions for Olympus' OM-D E-M1 which is similarly rated.
Olympus is taking a bet that this will become your next day-to-day lens for your compact system camera, and they have good reason to be confident: with a constant maximum aperture of f/2.8 and an amazingly convenient 24-80mm equivalent zoom range, this lens will meet the challenges of low light shots, wide landscapes, and captivating portraits. Think of it as the ultimate kit lens — all the convenience of the handiest zoom range, without the tradeoffs lower-cost lenses hand you in the aperture department. Precision M. Zuiko optics will keep everything sharp and clear, while capturing vivid yet natural colors.
