Infinity Photo-Optical Technology
All focusable Infinity instruments and/or lenses are internally-focused with our patented Afocal Variation System (AVS™) technology. The Model KC™ and InfiniMax™ utilize a variant
of AVS we call
InFocus™. The Proximity line of video lenses employ another type of
AVS called the Dynamic Focusing System (DFS™).
AVS, DFS, InfiniMax, InFocus and Model KC are trademarks of Infinity Photo-Optical
