ProOptic Discontinued (Depth of Field) Adapter for Video Cameras.

• The Pro Optic 645 (mid-format) Depth of Field Adapter is an affordable, lightweight system that allows the videographer to control depth of field (DOF) and create that desirable film look. It's compact enough for handheld indie shoots and perfect for setups using tripods, dollies etc.
• Because it uses a 2-1/4" x 1-5/8" vibrating viewing screen (twice the size of a 35mm screen) it reduces excess grain and projects a larger, brighter image on the screen.
