Alongside the OM-1 camera, OM Digital Solutions announced a pair of new OM System lenses, including the OM 40-150mm F4 PRO M.Zuiko Digital ED telephoto zoom lens. This all-new lens offers the same focal length as the Olympus 40-150mm F2.8 PRO lens but fills a different role and offers varied benefits. Along with its slower aperture, the 40-150mm F4 PRO lens is smaller, lighter and cheaper.

The size and weight of the OM 40-150mm F4 PRO lens is one of its biggest strengths. The lens weighs only 382g (13.5 oz.), which is about half the weight of the 40-150mm F2.8 PRO lens. The F4 zoom is only 99mm (3.9") long in its collapsed position, which is very compact for an 80-300mm equivalent lens. The compact form factor makes the 40-150mm F4 a great lens for handheld shooting and general walkaround photography.

Despite being smaller, slower, and less expensive than the 40-150mm F2.8 PRO, the 40-150mm F4 PRO lens still delivers excellent image quality and earns its 'PRO' designation. The lens is sharp throughout its zoom range and across the frame, even wide open. The lens also exhibits excellent control of aberrations and flare. You don't need to worry about sacrificing image quality by using the 40-150mm F4 PRO instead of the faster, larger and pricier F2.8 zoom. The lens includes different tradeoffs relative to the F2.8 lens, but it's far from a compromise regarding image quality.

The lens also delivers impressive autofocus. However, if you're using the new OM-1 camera, the OM 40-150mm F4 lens isn't compatible with the new mirrorless camera's 50 frames per second continuous shooting mode. Of course, the 40-150mm F4 is still well-suited to fast-paced photography.

Overall, the OM 40-150mm F4 PRO, which retails for $899, is a great option for Micro Four Thirds photographers looking for a compact, lightweight telephoto zoom lens that delivers excellent image quality.
