Weather Sealings of the OM System 40-150mm F4.0 PRO

The OM System 40-150mm F4.0 PRO is a weather-sealed lens, which provides extra protection to prevent water and dust get inside the lens and camera body under light rain, snow and wind. In order to have effective protection, you have to pair the OM System 40-150mm F4.0 PRO with a weather-sealed camera body such as the Panasonic G9 II, OM System OM-5 and Panasonic GH6.
