Overview
The fast Olympus M.Zuiko Digital ED 25mm F1.2 PRO lens lavishly uses special lens elements to suppress all types of aberrations and create beautiful bokeh. This lens provides excellent resolving power and beautiful defocusing effects from maximum aperture for natural, three-dimensional image quality. This lens is also equipped with a mechanism for high-speed, high-precision focusing. You will never miss a photo opportunity.
Features
Excellent resolving power even from maximum aperture
The M.Zuiko Digital ED 25mm F1.2 PRO makes lavish use of special lens elements to suppress spherical aberration and comatic aberration that can affect resolving power. These elements also suppress colour bleeding due to on-axis chromatic aberration, which tends to cause image quality issues on fast, large-diameter lenses. This construction enhances resolution from maximum aperture and faithfully communicates textures of subjects in the photograph.

Beautiful images with minimal colour bleeding
The M.Zuiko Digital ED 25mm F1.2 PRO suppresses colour bleeding often caused by on-axis chromatic aberration, for beautiful images.
The most beautiful bokeh
The M.Zuiko Digital ED 25mm F1.2 PRO features a design that gives consideration to aberrations in the focused areas as well as aberrations and shapes of objects in the defocused areas, achieving a smooth transition from the focused to the out of focus. Combined with the high resolution of the focused areas delivered at maximum aperture, a natural three-dimensional feel is realised.
Quick and accurate focus point capture
The M.Zuiko Digital ED 25mm F1.2 PRO uses an inner focusing system to drive AF with a single lens. This method suppresses aberration variations caused by focusing. Focusing is also quick, accurate, silent and smooth.
Limits comatic aberration to depict points clearly as points
The optical performance of the lenses thoroughly removes comatic aberrations that occur around the periphery of the image. Points of light are clearly depicted as points, providing for sharp, beautiful starscape photography even at maximum aperture.
Excellent close-up shooting ability
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.

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.

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.
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.
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.
