Olympus M. Zuiko Digital ED 12-100mm f/4 IS PRO Lens
The Olympus M. Zuiko Digital ED 12-100 mm f/4 is lens is a 24-200 mm equivalent zoom designed for non-mirrored Micro Four thirds cameras, which span an impressive telephoto telephoto range. Characterized by its constant maximum aperture of f/4, this lens offers constant performance across the entire zoom range to suit still and video images. Its optical design incorporates a large amount of low dispersion elements and aspherical elements to reduce chromatic and spherical aberrations, and has applied both a ZERO coating and a Z coating Nano to greatly reduce the flash and effect Phantom of the lens to enhance the contrast.
The Optical image Stabilization system works in conjunction with the 5-axis image stabilization of some cameras to form Sync IS, which compensates up to 6.5 camera motion stops. The high-speed image AF system, compatible with film and still Images (MSC), delivers fast, accurate, and quiet focus performance that fits well with photo and video applications, and a manual-focus clutch allows for rapid changeover to MF For more precise control. In addition, a lens function button is presented on the cannon side for direct configuration settings, and the lens also features a weather-sealed construction for use in harsh ambient conditions.
Spanning a wide-angle range to telephoto, this 12-100 mm zoom is designed for non-mirrored Micro Four thirds cameras and provides an equivalent focal length range of 24-200 mm.
F/4 's constant maximum aperture provides constant brightness throughout the zoom range to benefit both still images and video applications.
A double-sided aspheric element and three aspherical elements are presented in the optical design to limit spherical aberrations to improve sharpness with reduced distortion. In addition, five extra-low dispersion elements, two Super hr elements (high refractive index) and one HR element are also used to control chromatic aberrations and color edges for greater clarity and color fidelity.
Both ZERO coating and a Nano Z coating apply to individual lens elements to significantly reduce surface reflexes and avoid the flash and phantom effect of the lens to improve contrast and color neutrality in conditions of Intense lighting.
Lens-based image stabilization helps minimize the appearance of camera vibration to benefit manual shooting with this lens in difficult lighting conditions. In addition, this lens is compatible with Synchronized is, which combines the is optical system with image stabilization with 5-axis sensor change of certain Olympus cameras to control up to 6.5 camera motion stops.
An MSC auto-focus system provides fast, quiet, and accurate focus performance to benefit both shooting and film recording. In addition, a MF clutch is used to quickly switch to manual focus for more accurate control.
The weather-sealed construction protects the lens from dust and moisture to work in hostile environments.
The seven-blade circular diaphragm contributes to a pleasant quality of bokeh.
