With a focal length that ranges from wide-angle 40mm to a punchy 150mm, this lens is ideal for everything from portraits to sports and wildlife photography.

Build Quality and Design

Constructed with durability in mind, the OM System 40-150mm F4.0 PRO features a weather-sealed body that can withstand the elements, making it a reliable choice for outdoor shooting. The lens is lightweight due to its aluminum construction, making it easy to carry around for extended periods without causing fatigue. The zoom mechanism is smooth and responsive, allowing for quick adjustments while keeping the camera stable.

Optical Performance

Optically, the lens performs admirably across its focal range. With a constant aperture of f4.0, it provides good low-light performance and creamy bokeh, especially at the longer end of the zoom. The sharpness is commendable, even at f4.0, with minimal distortion and chromatic aberration. The lens also features special elements that enhance image quality and eliminate flare, ensuring vibrant colors and excellent contrast in various lighting conditions.

Autofocus System

The autofocus system on the OM System 40-150mm F4.0 PRO is fast and accurate, making it suitable for tracking moving subjects. The lens employs a linear motor for a quiet operation, which is a definite plus for videographers working in environments where noise is a concern. The focus acquisition is quick, although in low-light situations, it may hesitate slightly compared to some of its competitors.

Compatibility and Use Cases

Given its Micro Four Thirds designation, this lens effectively doubles its focal range due to the crop factor, yielding an impressive 80-300mm equivalent. This makes it an excellent choice for photographers who require that extra reach without carrying around bulkier, heavier glass. Its versatility makes it suitable for various genres, from wildlife photography to family portraits and events.
