35mm Lens Adapters for HD

Just heard about a fascinating type of lens adapter for shooting through 35mm prime/zoom lenses on HD cameras-- project the image through the 35mm lens onto (moving!) ground glass, then shoot the resulting image with the HD camera through its optics dialed to macro. It's an "analog hole" approach that BW says works great. Manufacturers:

• Letus
• Redrock Micro
• Cinevate Brevis MP.1

High end 35mm format digital motion picture cameras:

Panavision "Genesis"

Dalsa "Origin"

Arri "Arriflex D-20"

And soon....:o

Red "One"
