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 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.
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.
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 boke
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.
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.
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.

When focusing on a subject, there is an area behind and in front of the focused point that is also in focus. This area is called depth of field. The amount of area behind a focused point will always be greater than the area in front of the focused point regardless of aperture. Depth of field becomes deeper when the focal length is short (wide-angle lens), the focusing distance is long, and aperture is small.
