04-37831601Canon's 2nd Generation HDgc Series
The emergence of a new generation of cost-effective HDTV acquisition systems spurred Canon to create a new category of portable lenses to better match the price performance ratio of these cameras. This led to the introduction in 2006 of the new HDgc lens serires. Specifically targeted for HD ENG, these lenses retained the optomechanical robustness and ergonomics of the high-end HDxs lens series as well as the same digital drive units. Canon mobilized contemporary design tools and optical materials that facilitated a significant cost reduction while still maintaining an impressive overall HD imagining performance. In recognition of the continuing introduction of new improved 2/3-in ch HD acquisition systems and supported by a global end-user experiences, Canon is now introducing a second generation HDgc that reflects further design optimizations.
