Amazing Portability

This is the world's most compact, lightweight[*] lens among standard zoom lenses with a fixed aperture value. The lens features superb portability so the camera can be stored in your usual bag or hung from a neck strap when out and about for easy, comfortable shooting. When viewing the entire system with combined lens and camera body, it is approximately 70% the volume and approximately 62% more compact and lightweight than a full-frame interchangeable lens camera system, bringing out the best of the Micro Four Thirds System.

The World's Smallest and Most Lightweight Model[*]

The lens is 63.4 x 70 mm (max. diameter x length) in size, and weighs a mere 254 g. The world's most compact, lightweight* design was achieved by precision machining of 190 components, and carefully mounting each and every one in a dense configuration on the lens.

Compact, Lightweight System

When pairing the M.Zuiko Digital ED 12-45mm F4.0 PRO with the OM-D E-M5 Mark III, the entire system is approximately 113.3 mm long, and weighs nearly 668 g. Compared to a full-frame mirror-less camera with attached standard zoom lens that covers an equivalent focal length, it is approximately 70% less in volume and approximately 62% lighter.

Dustproof, Splashproof and Freezeproof

Sealing is included on nine of the lens for a dustproof and splashproof construction. When paired with a dustproof and splashproof performance camera body, you can shoot high image quality images with peace of mind in the harsh environments.

High-speed Focusing

1. Focusing lens

In order to enable speedy AF, a compact, lightweight focusing lens design was adopted. When combined with the high-performance AF system of a camera such as the OM-D E-M5 Mark III, this lens is capable of fast, accurate focusing when shooting moving subjects.

High Resolution

A compact, lightweight design and high image quality are achieved thanks to advanced optical technology. The lens delivers high resolution imaging at all focal lengths from 24 mm to 90 mm (35mm equivalent).

Lens Configuration for Sharp Imaging

A 12-element, 9-group lens configuration
1. High Refractive Index Lens
2. Dual - super Aspheric Lens
3. Super High Refractive Index Lens
4. Aspherical Lens
5. Extra-low Dispersion Lens

This lens basic optical configuration inherits from M.ZUIKO DIGITAL ED 12-40mm F2.8 PRO that is a well-recognized lens for its high resolution. Using special lenses such as ED lenses, DSA lens, and Super HR lenses in an effective layout for sharp imaging across the entire zoom range and frame. ZERO Coating is also applied to the appropriate lenses to reduce ghosts and flares.

Fixed Wide-aperture Across the Entire Zoom Range

A maximum aperture of F4.0 is achieved across the entire zoom range, from wide angle to telephoto shooting. Because the aperture value remains the same at any focal length, the exposure is easily kept stable while using the zoom in your shots.

Bright and Clear to the Edges

This lens suppresses peripheral light loss, resulting in bright, clear depictive performance to the edges of the frame.

Superb Macro Capabilities

An optical design that favors macro capabilities is utilized in this lens for amazing close-up photos when shooting right next to subjects.

Maximum Shooting Magnification of 0.5x across the Entire Zoom Range (35mm Equivalent)

The closest focusing distance is 12 cm at the wide-angle end and 23 cm at the telephoto end. Capture a range of 69.2 x 52 mm at a maximum image magnification of 0.5x (35mm equivalent) across the entire zoom range.

  • 1. Closest focusing distance
  Closest focusing distance Shooting magnification (35mm equivalent)
Wide-angle end (12 mm) 12 cm 0.5x
Telephoto end (45 mm) 23 cm 0.5x

Versatile Macro Expressions

This single lens is capable of wide-angle macro shots that emphasize a sense of perspective by capturing vast backgrounds, and tele-macro shooting for more significant background defocusing effects. With this, you can enjoy a diverse array of macro expressions that perfectly suit your shooting style.

  • Wide angle (12mm)
  • Tele angle (45mm)

Focus stacking

8 photos are captured at different focal positions and automatically composited into a single photo. Capture a photo with a large depth of field that is in focus from the foreground to background.
