The Olympus M.Zuiko 25mm f1.2 Pro Lens 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. The Olympus 25mm f1.2 Pro Lens 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.
The lens consists of 19 elements in 14 groups, with lavish use of special lenses such as 1 Super ED lens and 2 ED lenses. The lenses help suppress unfocused colour bleeding (axial chromatic aberration) common to large-diameter lenses. Also, the colour-canceling effects of E-HR lens and HR cemented lenses effectively correct colour bleeding (magnification chromatic aberration) at the screen periphery. An aspherical lens is placed near the aperture and multiple HR lenses are employed to achieve thorough suppression of comatic aberration common to large-diameter lenses. This advanced optical design results in excellent optical performance that delivers beautiful feathered bokeh and accurate depiction of points even at the widest aperture setting. 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. This lens has excellent close-up shooting abilities with a closest focusing distance of 30 cm, and shooting magnification of 0.11x (35mm equivalent: 0.22x). You can get closer to subjects to emphasize background bokeh.
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.
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.
