A closer look at the OM System’s modern upgrade with a weather-sealed 14-42mm lens

The new OM System M.Zuiko Digital 14-42mm f/3.5-5.6 III lens arrives with features that elevate it above its predecessor, including the addition of weather sealing. Its standout enhancements include improved weather resistance, allowing it to brave the elements more confidently with its IPX1 rating. Although this rating is basic—surviving light water exposure—it’s a notable advancement for photographers on the go.

One tangible change is in its focusing abilities. The optical device can now achieve focus at just 0.13 meters (5.1 inches) when set to its widest. This is a marked improvement from the previous version’s 0.25 meters (9.8 inches) minimum, enabling a higher maximum magnification of 0.26x. As zoom increases to 42mm, the focusing distance extends to 0.3 meters (11.8 inches), maintaining a reproduction rate of 0.19x.

Better weather sealing is complemented by a focus on agility and utility. This updated model, at 125 grams, marginally heavier than its predecessor, incorporates eight elements in seven groups, including three aspherical lenses. Its design accommodates larger filters, now at 46mm compared to the previous 37mm.

Availability and pricing

Available in late October, the lens is priced at $349.99 USD. While it’s available standalone, the lens will likely be most popular as part of a kit with the new OM System PEN camera—offered for a slight premium. For a more extensive setup, a kit combining this lens and the M.Zuiko Digital ED 40-150mm f/4-5.6 R zoom lens is also an option.

These attributes underscore the OM System’s dedication to developing versatile, rugged, and sharp optics for a range of photographic pursuits. The M.Zuiko Digital 14-42mm f/3.5-5.6 III lens enhances creative options for photographers while preserving the compact convenience that the industry has come to expect from OM System.
