Along with the OM-1 Camera (Amazon/ B&H/ Adorama), OM System 12-40mm F2.8 PRO II (Amazon/ B&H/ Adorama), OM System also announced the new OM System 40-150mm F4.0 PRO Lens. It is a weather-sealed telephoto zoom lens that offers an 80-300mm full-frame equivalent field of view. The lens is IP53 rated for dust- and splash-resistance when paired with a weather sealed camera, such as OM System’s new OM-1 Micro Four Thirds camera. It’s constructed of 15 elements in nine groups, uses a seven-blade circular aperture diaphragm and has a minimum focusing distance of 70cm (27.5″). The lens’ autofocus (AF) is driven via OM Systems’ Movie & Still Compatible (MSC) system, which OM Systems claims ‘benefits both photo and video applications due to its smooth, quiet, and fast performance.’
This new lens costs $899, first available for pre-order at Amazon/ B&H/ Adorama. It will start shipping from March 3, 2022.
