OM SYSTEM PRO 45mm f/1.2 Black Lens

The OM SYSTEM PRO 45mm f/1.2 Black Lens is engineered for exceptional image quality, offering a fast aperture for stunning depth of field and low-light performance. Its weather-resistant build and advanced optics make it a versatile choice for photographers seeking premium image quality and reliability. It is specifically designed for Micro Four Thirds camera systems, ideal for both photography and videography. The lens offers a wide aperture from f/1.2 (excellent for low light and achieving a shallow depth of field) to f/16 (suitable for achieving sharper images and greater depth of field in bright conditions). The 45mm focal length provides a 90mm equivalent perspective on a full-frame sensor, making it ideal for portraits and detailed close-ups.

An internal focusing with MF clutch allows for fast focusing without changing the lens' length and enables easy switching between autofocus and manual focus modes. It features MSC (Movie & Still Compatible) High-Speed Imager AF System which ensures rapid and quiet autofocus performances. The optical design is composed of one Extra-low Dispersion (ED) element reduces chromatic aberrations and color fringing for clearer and more color-accurate images. One aspherical element aids in controlling spherical aberrations and distortion for sharper images. Four high refractive index elements enhances overall optical performance by reducing refractive errors.

This lens is equipped with Z Coating Nano to minimize reflections, flare, and ghosting to produce clearer images. It also features a rounded nine-blade diaphragm, enhancing the aesthetic quality of the bokeh (out-of-focus areas) for more natural and pleasing portraits. Robust, weather-resistant construction allows the lens to be used in diverse weather conditions, making it a reliable tool for outdoor photography.

Product Features in Detail

M.Zuiko ED 45mm f1.2 PRO at a Glance
We’ve designed the M.Zuiko 45mm F1.2 PRO (90mm 35mm equivalent) with one goal in mind: to make your sharpest, most beautiful portraits effortless. You’ll shoot wide open at f1.2 and capture tack sharp subjects and smooth feathered bokeh with a depictive three dimensional result. We’ve included autofocus that’s fast and accurate, even at f1.2. Our most advanced lens coating virtually eliminates flares. And with splashproof and dustproof metal construction, a compact lightweight design, and our brightest aperture for superior low-light performance, this ultimate portrait prime will be one of your go-to lenses in every shooting environment.

High Performance
M.Zuiko PRO lenses are built for the highest level of performance, incorporating fast apertures and weathersealed construction.

Sharp at F1.2
At Olympus, we bring the very best optics to life. Tools designed to work better so your photography is better. This advanced F1.2 PRO lens combines ultra shallow depth of field and ultra high resolution at the maximum f1.2 aperture setting. Unlike other fast prime lenses, we’ve removed the need to stop down for improved performance, so you capture more beautiful photographs. 14 lens elements in 10 groups eliminate spherical and chromatic aberrations and suppress color fringing, and our very best Z Coating Nano suppresses flares from in-frame light sources. All to ensure that every portrait is sharp, clear, and exactly as you envisioned.

Feathered Bokeh
Beautiful background bokeh is a must for perfect portraits. To give you complete creative control, the 45mm F1.2 PRO provides two types of bokeh effects. Shoot wide open at f1.2 to produce feathered bokeh that transitions smoothly from sharp to defocused areas. The softer background appearance enhances your subject. Or, produce traditional solid bokeh by stopping down the aperture, enhancing shapes in the background. Combined with the razor sharp subject, you’ll create a natural three dimensional effect. And because the 45mm F1.2 PRO doesn’t use filters in its optics, light transmission is maximized for sharp details and stunning bokeh effects in both bright and low light.

Fast and Accurate AF
One of the keys to beautiful sharp portraits is focus. Some fast prime lenses compromise AF speed by using a large focusing mechanism with multiple elements. Fortunately, the 45mm F1.2 PRO is specially designed to be compromise-free. It uses a lightweight inner focusing mechanism with a single lens element to provide fast and sharp AF performance, even at the lens’ widest f1.2 aperture. Excellent close-up shooting capabilities help you to capture larger, more dramatic bokeh areas. And the Movie and Still Compatible mechanism provides quiet, smooth focusing – ideal for shooting video.

Leave the Rain Gear Behind
Easily capture shots in challenging conditions without worrying about your gear. The 45mm F1.2 PRO’s premium metal construction is hermetically sealed to be splashproof, dustproof, and freezeproof (all the way down to 14°F / -10°C). Its optics are efficiently designed so that overall size and weight are significantly less than what you’ll find with other fast prime lenses. It’s the perfect complement to a compact weatherproof OM-D camera, a combination that’s ideal for all day handheld shooting in any environment.

Pro Convenience & Control
We’ve designed the 45mm F1.2 PRO to give you efficient and convenient control of your gear. The customizable Lens Function Button (L-Fn) lets you control your choice of camera functions right from the lens barrel. Programmable functions include Focus Peaking, AF Stop, and Magnify. The Manual Focus Clutch on the lens’ focus ring lets you instantly shift between auto and manual focus. You can preset a focus position using the easy-to-read distance meter, and by pulling the ring toward you, instantly return to that position from AF mode.

F1.2 Pro Series
We’ve designed the F1.2 PRO series with you in mind. No matter which focal length you choose – the 17mm for landscape and street photography, the normal 25mm, or the 45mm for portraiture – you’ll find a compact weathersealed design engineered to exacting standards. Each lens produces sharp resolution and smooth feathered bokeh at the maximum f1.2 aperture setting. And with the highest AF speed and accuracy, you’ll enjoy consistent beautiful results over and over again.
