Olympus has introduced the M.Zuiko Digital ED 12-45mm F4 Pro, a premium standard zoom lens for Micro Four Thirds. The lens is remarkably compact; it's 70mm (2.8") long and weighs just 254 grams (9 ounces). The 12-45 is also weather-sealed, to IPX1 standards, something that very few lenses can claim. For the sake of comparison, Olympus's 12-40mm F2.8 Pro is 84mm (3.3") long and weighs 382 grams (13.5oz) but is a stop faster.

The 12-45mm F4 has a total of 12 elements, including HR (high refractive), Super HR, DSA (dual super aspheric), aspherical and ED (extra-low dispersion) glass. A 'ZERO' coating reduces flare, ghosting and other aberrations. The lens can focus as close as 12cm (4.7") and has a maximum magnification of 0.5x.

The Olympus 12-45mm F4 Pro will be available in April for $649.

Press release

The ultimate compact, lightweight, high-resolution M.Zuiko® pro lens: M.Zuiko Digital ED 12-45mm F4.0 PRO

CENTER VALLEY, Pa., February 12, 2020 — Olympus is pleased to announce the M.Zuiko Digital ED 12-45mm F4.0 PRO[1] lens, scheduled for availability April 7, 2020. This high-performance medium range zoom PRO lens conforms to the Micro Four Thirds® System standard and features superb optical performance at all focal lengths, while being the world’s most compact, lightweight model[2]. The M.Zuiko Digital ED 12-45mm F4.0 joins the M.Zuiko PRO category of lenses, possessing dustproof, splashproof and freezeproof (-10°C) performance that delivers excellent image quality and peace of mind even when shooting in the most severe environments. This lens delivers superb resolution to the edge of the frame across the entire zoom range, making the most of the appealing aspects of the Micro Four Thirds System standard. It features supreme macro capabilities with a maximum magnification of 0.5x (35mm equivalent) across the entire zoom range, making it an anytime, anywhere, all-around lens. When paired with the Olympus OM-D® E-M5 Mark III, this lens delivers high resolution and amazing portability to conveniently carry in a small bag.

The M.Zuiko Digital ED 12-45mm F4.0 PRO lens is the world’s most compact, lightweight medium range zoom PRO lens with a fixed aperture value covering a focal length from wide angle 24mm to telephoto 90mm (35mm equivalent). It consists of nearly 190 precision machined components all mounted in a dense configuration, resulting in a size of 63.4 mm./2.5 in. (max. diameter) x 70 mm/2.76 in. (overall length), and a weight of approximately 254 g/8.96 oz. This small and lightweight lens delivers high-speed, precise autofocus for capturing any subject. Its dustproof and splashproof construction contains sealing in nine places to keep out dust and rain, providing peace of mind when shooting in active situations[3].

Effective placement of aspherical lenses and ZERO (Zuiko Extra-low Reflection Optical) Coating provide clear depictive performance, drastically reduce aberrations, ghosts, and flare for sharp, high-definition image quality. Suppressing loss of light at the edges of images makes it possible to obtain bright, clear depictive performance up to the very edges. Because the aperture value is fixed across the entire focal length, it is easy to control the exposure when zooming and when recording video.

Enjoy macro shooting with a maximum magnification of 0.5x (35mm equivalent) across the entire zoom range. The closest focusing distance is 12 cm at the wide-angle end, and 23 cm at the telephoto end, delivering a wide range of macro shooting effects, including wide-angle macro shots that emphasize a sense of perspective by capturing vast backgrounds, and telephoto macro shots for more significant background defocusing effects. Diverse macro effects are possible, such as Focus Stacking[4], which generates a single image on the camera with a large depth-of-field in focus from the foreground to the background.

Pair the new M.Zuiko 12-45mm F4.0 PRO lens with the recently announced Olympus OM-D E-M5 Mark III to create the ultimate travel combination. As Olympus’ smallest weathersealed combination to date[5], at just 670 g/23.6 oz., you are able to travel with ease and shoot on-the-go, no matter the environment. Enjoy a bright constant aperture of F4.0, along with a myriad of pro features brought to you in the OM-D E-M5 Mark III. Lighten up with this ultimate travel combo and change both your photography and lifestyle forever.
