"I've been waiting ten years for a lens like this." -- Brant S. Fagan, SOC. .

"Just to let you know what a fabulous lens you have made and how much we have been using it. For night work on cranes it saves a lot of messing about changing lenses, and for Steadicam work it has saved us a lot of time by using the various focal lengths in succession. Optical quality is excellent and the assistants have given me no complaints about the handling of the lens." -- Oliver Stapleton, BSC, on location May 2006 shooting a feature film "The Water Horse.".
