Canon KJ22ex7.6B IRSE/IASE hakkında ayrıntılı bilgi edinin
The KJ22ex7.6B is a telephoto lens covering a generous range of focal lengths while also providing a modest wide-angle of almost 65 degrees in the 16:9 HD image format. This provides a very flexible image framing range especially for outdoor applications. The KJ22ex7.6B has excellent balance between size, weight, and HD optical performance intended for HD News and many HD production applications.
The KJ22ex7.6B deploys Large Diameter Aspherical lens elements that contribute to a better control of cromatic aberration, geometric distortion, and corner resolution. Curvature of field and chromatic aberrations have been reduced by use of special optical materials that include Fluorite and Hi-UD glasses.
Newly developed optical glass materials each having unique dispersion characteristics allowed improved control over chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved contributing to improved MTF performance. New Multilayer Optical Coatings combined with new deposition processes produce an improved optical contrast ratio.
Enhanced Digital Drive technology provides precision control of the three servo systems for zoom, iris and focus while also facilitating new developments in lens-camera correction of lateral chromatic aberration. Canon's patented Micro Roofmirror Array (MRA) technology underlies the unique miniature 16-bit rotary encoders that are used for each of the zoom, iris, and focus position detection (each with a positional accuracy of 0.1 micrometer). Dynamic Zoom Speed Range can be adjusted from 0.5 seconds to 5 minutes (from wide to telephoto extremes)
The Digital Drive Unit was totally redesigned ergonomically to facilitate greater comfort and improved actuation of lens controls, and provides a wider separation that allows the other hand to more easil
