Concept of HDgc Series
Corresponding to the digital High Definition broadcasting and diversity of HDTV equipment & Canon has added a new series to its HDTV lens line up & the HDsc 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.
Another important policy of Canon's is not to pollute the earth and the HDgc series succeeded in excluding harmful substances such as cadmium & PBBS & PBDPE or mercury from the mechanical parts & and at the same time incorporating lead free glass and reducing the amount of hazardous substances used in electrical parts.

The new design enables the user to fully bring out the digital functions.

During a performance & framing preset will reproduce the zoom position decided upon at the rehearsal. It is easy to repeat the same zoom as often as you like at the highest speed or in a preset zoom speed.
