Our Depth of Field Attachment is a RedRock M2 Encore, a completely re-designed model from 2009. It loses only ½-stop of light. We have it with a Flip Prism so the image recorded is upright, and with Focus Control. Both of these options make shooting easy and precise. The whole rig is set up for our High Def EX3 camera, but can be adjusted for any camera with a 77mm or 72mm front lens filter thread.
20mm f/3.5 (very cool wide-angle)
50mm f/1.4 (low-light standard lens)
85mm f/2 (classic portrait lens)
135mm f/2.8
(perfect for outdoor interviews)
All Nikon lenses
The lenses we use are exclusively vintage Nikon Nikkor AI or pre-AI models because of their no-compromise mechanics, designed in the 1970s at the peak of manual operation photography. The list of lenses is likely to grow over time because they are affordable and we can buy exactly what we want and need for any particular job.
35-70mm f/3.5

How does it work?
A still camera lens projects a 35mm-sized image onto a spinning disk of ground glass, located in the boxy portion of the attachment. The video camera's own lens then shoots this image. The motor-driven disk must spin in order to smooth out the grainy texture of the ground glass.
Since a lens always inverts a picture, just adding a lens would make the video upside down. So a prism flips the image back to its desired orientation. The prism is the part of the attachment which offsets the axes of the front and back lenses.
