OM System M.ZUIKO DIGITAL 40-150mm F4 Micro 4/3 PRO Lens 

The M.Zuiko Digital ED 40-150mm F4.0 PRO (35mm equivalent: 80-300mm) is a compact, lightweight telephoto zoom lens that covers a broad focal length range from mid-range 80mm equivalent to telephoto 300mm equivalent. This high-performance M.Zuiko PRO lens is the world's most compact, lightweight model, featuring a fixed maximum aperture value of F4.0.

1.  The world's most compact, lightweight and high image quality telephoto zoom lens

• Excellent resolution across the entire zoom range from 80mm to 300mm

This lens uses the same fundamental structure as the M.Zuiko Digital ED 40-150mm F2.8 PRO, which is well known for its high resolution, and incorporates an optical design with 15 elements in 9 groups (2 ED lenses, 1 Super ED lens, 1 HR lens and 2 aspherical lens). An effective layout of special lenses helps to thoroughly suppress chromatic aberration, which tends to occur on telephoto lenses, and delivers high-resolution imaging from the maximum aperture value across the entire zoom range and frame while maintaining a compact and lightweight form. The lens also features ZERO (Zuiko Extra-low Reflection Optical) coating, thoroughly eliminating ghosts and flares for clear depictive performance even in difficult conditions such as backlit scenes. This high-performance lens fully utilizes the high image quality performance of the camera body even with High Res Shot mode.

• The world’s most compact, lightweight model delivers unrivaled portability, and an inner zoom system improves usability

A retracting mechanism makes this the world’s most compact, lightweight model as a fixed aperture value, 300mm equivalent (35mm equivalent) telephoto zoom lens, measuring approximately 99.4 mm long (124 mm long when in use) and weighing approximately 382 g, making it amazingly compact and lightweight. The lens was designed with a focus on ease of use when shooting and is equipped with a mechanism that makes it possible to retract and store the lens simply by turning the zoom ring. It also uses an inner zoom system that keeps the lens length the same across the entire focal length, suppressing center of gravity changes while zooming. Using compact, lightweight lenses in the front drastically reduces the feeling of heaviness, eliminating the long lens barrel and weight at the front of the lens, which is common to telephoto lenses, making shooting easier and more well-balanced.

2. Closest focusing distance of 70 cm (at all focal distances), and macro capabilities with a maximum image magnification of 0.41x

This model features a closest focusing distance of 70 cm across the entire zoom range, just like the M.Zuiko Digital ED 40-150mm F2.8 PRO. At the telephoto end, close-up shooting is possible up to a maximum image magnification of 0.41x. Despite being a telephoto zoom, this lens also possesses superior close-up shooting performance for a wide range of applications. Focus Stacking3 is also supported, which captures multiple shots at different focal positions, and then automatically composites the shot. When paired with a compatible camera, this mode lets you take macro photos that are completely in focus from the front to the back.
