Olympus M. Zuiko 17mm F1.2 Pro Lens Black

Sporting a bright and fast F/1.2 to F/16 Aperture Range and focal length of 34mm (35mm Equivalent), the OM System EW-M1712 M. Zuiko 17mm F1.2 Pro Lens Black for Micro Four Thirds System offers a versatile wide-angle view for mirrorless cameras. Built with Z Coating Nano, this lens reduces flare and ghosting to achieve the high quality contrast in every shot. Four ED Elements and One ED-DSA Element plus the Super HR, EDA, and Aspherical Elements help build excellent chromatic aberration correction. The Internal Focusing, MF Clutch allows faster switching of the lens from AF to MF. MSC High-Speed Imager AF System provides smooth, quiet, and fast focusing that is perfect for stills and video recording. Rounded Nine-Blade Diaphragm is also featured to achieve smoother bokeh. The lens is built with weather sealed construction that makes it dustproof, splashproof and freezeproof.  

Product Features in Detail

Beautiful feathered bokeh from the maximum F1.2 aperture
The M.Zuiko Digital ED 17mm 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 made possible by an ultra-high precision aberration measurement instrument
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.
The M.Zuiko Digital ED 17mm F1.2 PRO adopts 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.

High resolution from lavish use of special lenses
This lens employs 6 ED lens elements, the most of any M.Zuiko lens, including the newly developed ED-DSA lens, which incorporates the features of both ED (Extra-low Dispersion) and DSA (Dual Super Aspherical) lenses. This construction effectively compensates for unfocused colour bleeding (axial chromatic aberration) which is a common problem on large-diameter lenses, and colour bleeding (magnification chromatic aberration) at the image periphery. It also contributes to creating beautiful feathered bokeh, and achieving superb optical performance which accurately represents points as points even at the widest aperture setting.

The ED-DSA lens which uses ED glass on a DSA lens has been successfully mass-produced for the first time ever by Olympus. This lens delivers the excellent chromatic aberration correction abilities of the ED lens and the spherical aberration, comatic aberration, and astigmatism correction abilities of the DSA lens in a single lens. Incorporating the ED-DSA lens significantly reduces the number of lens elements, resulting in a shorter overall length of the lens body while providing higher performance.

Excellent close-up shooting ability
This lens has excellent close-up shooting abilities with a closest focusing distance of 20 cm, and shooting magnification of 0.15x (35mm equivalent: 0.3x). You can get closer to subjects to emphasize background bokeh.

Z Coating Nano for 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 making fast and silent AF possible
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 focusing 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.

DSLR (Phase detection AF)
Current SLRs are limited to F2.8 light fluxes. Because there is no sensor for focusing at F1.2 light fluxes, AF precision is not guaranteed when a lens brighter than F2.8 is attached.

OM-D E-M1 Mark II (On-chip Phase detection AF)
On-chip Phase Detection AF has no light flux limitations, making high-precision focusing with all-cross AF possible even when a large-diameter F1.2 lens is attached.

Eye Priority AF demonstrates its power during portrait shooting
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.

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

Reliable dustproof, splashproof, and freezeproof construction
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.

Controls that meet the demands of pros
Controls are designed to meet the demands of pros, including a focus ring which provides for comfortable focusing, and an L-Fn button which can be operated as you keep your eye to the viewfinder.
