Olympus M.Zuiko Digital ED 45mm f/1.2 PRO Lens

This large-diameter medium telephoto lens features the perfect 90mm focal length (35mm equivalent) for portraits. Commitment to a lens design that delivers smoothly blending, beautiful defocusing effects and excellent resolution result in outstanding imaging performance.

Beautiful Feathered Bokeh

The M.Zuiko Digital ED 45mm F1.2 PRO delivers beautiful feathered bokeh that blends the image from focused sections to out-of-focus sections and provides a smooth impression to the defocused background, providing more depth to the image by making the subject stand out further.

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

High Resolutoin from 3 Cemented ED Lenses

Optimal placement of 3 cemented ED lenses effectively correct  unfocused colour bleeding (axial chromatic aberration) common to large-diameter lenses as well as colour bleeding (magnification chromatic aberration) at the screen periphery. Also, an aspherical lens is placed near the aperture and 4 HR lenses are employed to achieve thorough suppression of comatic aberration. The optimal lens placement for a medium telephoto lens results in excellent optical performance that delivers beautiful feathered bokeh and accurate depiction of points even at the widest aperture setting.

Excellent Close-Up Ability

This lens has excellent close-up shooting abilities with a closest focusing distance of 50 cm, and shooting magnification of 0.1x (35mm equivalent: 0.2x). You can get closer to subjects to emphasize background bokeh.

Z Coating Nano - Clear Image Quality

Coating technology is employed which coats the lens surface with a layer of nanoscale size particles that have air in the centre, resulting in a coating with a similar refractive index as air and reduced surface reflection. Ghosts and flaring are significantly reduced for sharp, clear image quality.

MSC Mechanism - Fast & Silent AF

Despite being a large diameter F1.2 lens, a lightweight focusing unit is made possible via the MSC (Movie & Still Compatible) mechanism. A screw drive mechanism is used as the core drive system of the MSC mechanism, and a stepping motor is used as the drive motor.

High-Precision AF Across All Focus Points

On-chip Phase Detection AF used on the OM-D E-M1 Mark II has no light flux limitations, making all-cross AF possible even when a large-diameter F1.2 lens is attached. This provides coverage for the all focusing points to the edges of the image for high-precision focusing.

Eye Priority AF

When used in conjunction with Eye Priority AF on the OM-D E-M1 Mark II, it is possible to capture portraits that are sharply focused on the subject's eyes.

Dustproof - Splashproof - Freezeproof

Hermetic sealing across the entire lens results in highly reliable dustproof, splashproof, and freezeproof performance. You can feel comfortable shooting anywhere, never worrying about dust, rain, or inclement weather.

Amazing Compact & Lightweight Design

This large-diameter, maximum aperture F1.2 lens remains compact and lightweight. It is approximately 400 g, resulting in an amazingly compact lightweight system at only approximately 974 g when paired with the OM-D E-M1 Mark II.
