Features


A compact PRO lens that continues the legacy of feathered bokeh

This compact, high-performance lens features the same feathered bokeh as the M.Zuiko Digital F1.2 series and the excellent image quality of a PRO lens.

High resolution

Advanced optical technology provides the high resolution appropriate for an M.ZUIKO PRO from the center to the corners of the image.
A high-resolution lens suitable for High Res Shot.

To provide superb depictive performance, this lens utilizes one Super ED lens, three ED lenses, two Super HR lenses, and two aspherical lenses in a configuration of 11 elements in 10 groups to provide clear, sharp images right to the periphery of the image despite being a bright F1.4 lens.
ZERO coating is used effectively together with optimal suppression of internal reflections within the lens barrel to reduce ghosting and flaring.

Lens construction of 11 elements in 10 groups.

  • ⅠSuper HR lens
  • ⅡSuper ED lens
  • ⅢED lens
  • ⅣAspeherical lens

Feathered bokeh

"Perfecting Bokeh" Using the know-how gained with the M.ZUIKO PRO F1.2 Series, we have achieved feathered bokeh that slowly introduces blur moving from the in-focus area to the out-of-focus region.

Beautiful feathered bokeh was achieved thanks to an ultra-high precision aberration measurement instrument incorporating high-precision measurement technologies used in advanced microscope design.
This measurement instrument was used in research stages to measure the characteristics of historically acclaimed lenses, which would become the base for newly developed ones.
In development stages, the instrument was used to create a lens design that optimizes the level of aberrations, while virtually eliminating all unwanted aberrations.

Adopting a design which intentionally guides light beams passing on the outside edges of the lens to form an image in the foreground, while gradually tilting the lens as the spherical aberration moves towards the outside edge. Intentionally keeping spherical aberrations results in beautiful feathered bokeh.

Compact and lightweight

A bright F1.4 lens that remains compact and lightweight.
Weighing 247g, this is compact and lightweight, just 662g when paired with the OM-D E-M5 Mark III.
A beautifully portable combination for spontaneous photo opportunities.


Enjoyable shooting in range of environments

With splashproof performance equivalent to protection class 1 (IPX1) and freezeproof performance to -10°C, you can enjoy shooting with peace of mind in even the most punishing environments.

Highly reliable dustproof, splashproof and freezeproof performance

Sealed throughout, this product has excellent splashproof properties, offering IPX1-class protection. It is splashproof, as well as being freezeproof to -10°C. Pairing this lens with a dustproof, splashproof, and freezeproof camera body makes it possible to continue shooting in punishing environments such as rain and snow—and even dusty environments—with peace of mind.

Fluorine coating

Fluorine coating on the front element. Water droplets flow off readily, making shooting in the rain stress-free.

  • Without fluorine coating
  • With fluorine coating

Fluorine coatings repel oil and water, provide stain resistance and reduce friction, making it easy to remove dirt from the lens.

Fast & high precision AF

Superb optical design and lens processing technologies make a focusing lens lighter. This allows rapid, precise AF, for stress-free shooting.


Offering a wealth of expression in any field

Its unique 40mm equivalent angle of view makes it perfect for landscapes, portraits, snapshots, still life photos, and other everyday shooting scenarios. Its feathered bokeh effects also make a versatile range of photographic expressions possible.

Close-up shooting that makes the most of feathered bokeh.

Enjoy taking amazing close-up photos using a magnification of up to 0.22x[1] when shooting right next to subjects at distances as close as 25 cm.
Macro shooting using beautiful bokeh that blends in gradually from the in-focus section to the out-of-focus areas, will inspire your creativity.

Equivalent to 40mm focal length (35mm equivalent)

This focal length offers a unique angle of view a little wider than a classic standard lens but less than a traditional wide angle, balancing a natural, unexaggerated perspective with bokeh expression at a maximum aperture. This is the perfect lens using with the feathered bokeh to blur the background at a maximum aperture of f1.4 to take portraits at a comfortable distance from the subject, for landscape photography with a natural viewing angle, or for snapshots where you can get close to the subject and then pull back to capture the shot.
