Rate & Review

The J17ex7.7B IRSE Broadcast Zoom Lens with 2x extender is the industry standard broadcast quality SD lens by its manufacturer Canon. The J17ex7.7B IRSE has the eIFxs technology, consists of two meanings that start from the letter "e". One is the "Ecological Design", the design harmless to the environment. The other is the "enhanced digital" technology which improves the performance of the digital drive unit. Of course, the new series inherits all the advantages from its predecessor, the IFxs series which includes the advanced optical design concept, based on the X element technology.

The eIFxs series is equipped with and informational display and a Digital Function Selector so that the user can customize the enhanced digital funtions much more easily and precisely. This new design enables the user to bring out the digital funtions fully. In addition, the drive unit can memorize 9 patterns of user customized settings and also transmit the data between different drive units.
