OM System M.Zuiko Digital ED 45mm f/1.2 Pro Lens Black

An Ideal Portrait-length Lens

The OM System PRO 45mm f/1.2 lens is a mirrorless lens ideal for portraiture, with a highly desirable 90mm-equivalent focal length and a bright maximum f/1.2 aperture that offers great creative control. This combination enables you to create a distinct shallow depth of field for razor-sharp subjects in contrast to a smooth, feathered bokeh. It also enables superb handling in difficult lighting conditions. Whether it’s an indoor portrait in ambient light or you’re outside in the full sun with a colourful background, you’ll be wowed by the results you can achieve.

High-quality Build for Outstanding Clarity

Thanks to the high-quality construction of this prime OM System PRO 45mm f/1.2 lens, outstanding results are guaranteed: crisp edge-to-edge sharpness, true colour reproduction and reduced aberrations. This is thanks to the incorporation of low dispersion, aspherical and high refractive index glass elements as part of the lens build, which has a total of 14 elements in 10 groups. It also features a rounded nine-blade diaphragm which contributes to the smooth bokeh effects that can be created with this lens.

Focus with High-speed Precision

Whether you’re photographing a child who can’t sit still for a long period of time or an adult in an atmospheric, indoor setting with low light, the OM System PRO 45mm f/1.2 lens features an MSC High-Speed Imager AF System that won’t let you down. Along with an internal focusing design, it is capable of delivering fast and silent focusing that is highly precise – ideal for both stills and video. The lens also features an MF clutch so you can quickly change to manual focus when greater control is required. The result: crystal-clear images that you’ll love. 

Anti-reflective Coating

The OM System PRO 45mm f/1.2 lens features the signature Olympus ZERO (Zuiko extra-low reflection optical) coating on each of the individual lens elements. This works to limit flare and ghosting to deliver top-notch images that show incredible clarity and colour, free of unwanted distortion.

From the snowy peaks of Japan to the dusty wide open plains of Africa, this durable lens will prove a durable piece of equipment that is also reliably high-performing, making it a must-have in your kit.

How to Use & Care

To get the most out of your OM System 45mm f/1.2 Pro Lens, pair it with a weather-sealed mirrorless camera body to fully utilise its splash, dust, and freeze-proof capabilities in the field. When shooting portraits, open the aperture to f/1.2 to maximise background blur and draw attention to your subject. Use the convenient MF clutch by pulling the focus ring toward the camera body when you need precise manual focus overrides, especially for macro-style detail shots or complex video movements. Keep the front element clean and protected with a quality UV filter, and wipe down the lens barrel with a microfibre cloth after shooting in dusty or wet environments.
