Olympus M.Zuiko Digital ED 25mm f/1.2 PRO Lens

The M.Zuiko Digital ED 25mm f/1.2 PRO Lens from Olympus is a high-speed, standard-length prime lens that boasts an advanced optical design. Designed for Micro Four Thirds mirrorless cameras, this lens provides a 50mm equivalent focal length. Its sophisticated construction comprises 19 elements arranged in 14 groups, incorporating extra-low dispersion, aspherical, and high refractive index elements. This design effectively minimizes both chromatic and spherical aberrations, resulting in exceptional image clarity, sharpness, and color fidelity. The lens features a bright maximum aperture of f/1.2, which enhances performance in low-light situations and offers significant control over depth of field. Additionally, it includes a nine-blade aperture that produces a pleasing bokeh effect when utilizing shallow depth of field techniques. A Z Coating Nano has been applied to the individual elements to reduce flare and ghosting, thereby enhancing contrast.

In terms of physical attributes, the lens is constructed with weather-sealing, making it suitable for use in challenging environmental conditions. It is equipped with a Movie & Still Compatible (MSC) autofocus system, ensuring smooth, quiet, and rapid focusing performance, ideal for both photography and videography. Furthermore, a manual focus clutch allows for swift transitions to manual focus control, and a printed depth of field scale is present on the lens barrel to facilitate pre-focusing and hyperfocal focusing methods.

• Standard prime 25mm lens is designed for Micro Four Thirds mirrorless cameras and provides a 50mm equivalent focal length.
  
  
• Exceptionally fast f/1.2 maximum aperture supports working in difficult lighting conditions and affords extensive control over depth of field for selective focus techniques.
  
  
• The intricate optical design employs one Super Extra-Low Dispersion element, two extra-low dispersion elements, one Extra High Refractive Index element, three high refractive index elements, and one aspherical element, which all work in concert to control chromatic and spherical aberrations for improved clarity, reduced color fringing, and enhanced sharpness.
  
  
• A Z Coating Nano has been applied to individual lens elements to noticeably reduce surface reflections and prevent lens flare and ghosting for improved contrast and color neutrality in strong lighting conditions.
  
  
• A MSC autofocus system, along with an internal focusing design, provides quick, quiet, and precise focusing performance to benefit both still photo shooting and movie recording. Additionally, an MF clutch is used for fast changing to manual focus for more precise control.
  
  
• Programmable L-Fn (lens function) button for easily accessible settings adjustment.
  
  
• Weather-sealed construction guards the lens against dust, moisture, and freezing temperatures for working in harsh environments.
  
  
• Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
