Description

Due to this lens only being produced in a Canon or Nikon mount, a Canon to micro four thirds adapter is included. This adapter allows you to attach any manual-focus Canon lens to your Panasonic M4/3 mount camera.

The 135mm f/2.8 LD UNC AL Lens from Oshiro is full frame and APS-C compatible prime medium telephoto lens that offers a wide maximum aperture, vibrant color rendition and attractive out-of-focus background. It maximum aperture of f/2.8 provides substantial light gathering for sharp, high resolution imaging and lovely shallow depth of field photography. A nine-blade circular aperture will offer harmonious background blur when shooting with minimal depth of focus.

One extra-low dispersion (LD) element is incorporated within the design that helps to greatly reduce chromatic aberrations for increased clarity, sharpness, and color accuracy when photographing in strong lighting conditions. Ultra nano crystal multi-coating eliminates lens element reflections and reduces ghost and flare. It is a compact lens for its focal length and its enhanced optical design consists of 9 lens elements in 7 groups with minimal glass-to-air surfaces. The lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. The metal barrel of the lens is complemented by depth of field and distance scales, which pair with the manual focus design for greater control and use of pre and zone focusing techniques. The physical design also incorporates a retractable lens hood that helps to minimize lens flare and ghosting.
