Concept of the HDgc Series
Corresponding to the popularity of digital High Definition broadcasting and diversity of HDTV equipment, Canon has added this series to its HDTV lens line up, the HDgc series. The HDgc series supports the emergence of an important new generation of cost-effective HD acquisition systems. Adopting the advantages created by Canon's unique technology, the HDgc lenses exhibit high MTF, high resolution and high contrast from the center of the image to its extreme edges, meanwhile maintaining its compact size and weight.

Compared to the SDTV Lenses, the HDgc Series are...
In the HDTV system the pixel size is about half. Therefore, the spread of a point image caused by a spherical aberration, coma etc. should be diminished to about half. The MTF varies as the focus changes and even if the image is slightly out of focus, the MTF is greatly influenced. The HDgc Lenses are specially designed to use optical elements that are effective in further minimizing chromatic aberrations, such as "Hi UD Glass", "Aspherical Elements" and other special elements. The HDgc lenses greatly contribute to correcting and minimizing these aberrations at the same time maintaining high MTF throughout the edge of the picture.

Quality of the HDgc Series
The HDgc Series lenses are based upon Canon's latest design concepts which support the new generation of cost-effective HD acquisition systems. The HDgc lenses are designed to meet the specific bandwidth frequency (or the number of scanning lines) of these new HD camera systems and at the same time to offer an excellent performance-cost optimization.
