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 series. 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 perfomance. In recognition of the continuing introduction of new improved 2/3-inch HD acquisition systems and supported by a global experience, Canon is now introducing a second generation HDgc that reflects further design optimizations. The first of these new lense is the KJ17ex7.7B
