Olympus M.Zuiko Digital ED 45mm f/1.2 PRO Lens

The M.Zuiko Digital ED 45mm f/1.2 PRO lens from Olympus is an exemplary portrait-length option for Micro Four Thirds photographers, offering a focal length equivalent to 90mm and an impressive maximum aperture of f/1.2. This combination of a slightly narrower field of view and a bright aperture facilitates the creation of striking shallow depth of field images, making it particularly effective in challenging lighting situations. The lens boasts a sophisticated optical design comprising 14 elements arranged in 10 groups, which includes low dispersion, aspherical, and high refractive index glass elements to minimize various aberrations and distortions, ensuring exceptional sharpness, clarity, and color accuracy. Additionally, it features a nine-blade aperture that produces a pleasing bokeh effect when utilizing shallow depth of field techniques, while a Z Coating Nano has been applied to individual elements to reduce flare and ghosting, enhancing overall contrast.

In terms of its physical attributes, the lens is constructed with weather-sealed materials, making it suitable for use in adverse weather conditions. It is equipped with a Movie & Still Compatible (MSC) autofocus system that delivers 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 included on the lens barrel to assist with pre-focusing and hyperfocal focusing methods.

• Portrait-length 45mm lens is designed for Micro Four Thirds mirrorless cameras and provides a 90mm equivalent focal length.
  
  
• Notably 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 complex optical design incorporates one extra-low dispersion element, four 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.
  
  
• An 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.
