Canon YH12x4.8 Series SDTV Pro-Video Len
Canon Updated: 2007-06-18The YH12x4.8 is a very wide angle of view portable ˝-inch Pro-Video lens offered by Canon to support a broad range of business & industrial and corporate production applications. It is a key member of a family of five portable ˝-inch lenses that collectively offer an unusually broad range of creative options to these communities.
This particular lens is intended for producers having as their foremost priority very wide angle shooting with a lightweight mobile production lens-camera system that offers superb performance.
The YH12x4.8 utilized advanced technologies and powerful computer-aided design techniques to produce a very wide-angle and high-sensitivity (maximum aperture of f1.5) lens in a lightweight 3.9 lb package. It is a design directly responding to the expressed creative desires of producers for a versatile acquisition system.
ABOUT THIS LENS
The YH12x4.8 KRS-A represents a fine compromise between the demands for lightweight and mobility in a handheld camera system and the performance requirements for high-end Pro-Video production. This lens provides a 67.4-degree horizontal field of view and a focal range from 4.8mm to 58mm. The alternate YH12x4.8 IRS-A has a built-in 2x extender that can extend this focal range from 9.6mm to 116mm.
The requisite optimization strategies to achieve this balance sought a high MTF over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Preservation of the highest MTF at the wider-angle focal lengths (where scene detail can be particularly high) was a special priority. Contrast was extended by superb control of black reproduction - with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections.
