Concept of the HDgc Series Corresponding to the popularity of digital High Definition broadcasting and diversity of HDTV equipment, Canon has added a new series to its HDTV lens line up, the HDgc series. The new 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 new 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 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. These elements will decrease the flare that causes blurring of the picture and enables the lens to keep a high MTF. • Setting a higher standard for parts quality and are designed to improve the lens structure. The HDgc lens manufacturing process has become tighter with reduced tolerance's to maintain a higher lens performance. 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. |
