A short stop motion clip of my homemade DOF camera (made in 2011).
In the summer of 2011 I decided to upgrade my regular AVCHD camcorder to a semi-pro camera. The best way to go was to assemble a so called DOF-adapter. With this device you can mount your (d)slr lenses to your camcorder and create shallow depth-of-field shots. Who needs a DSLR anyway?
Off course, it’s much easier to use a DSLR to achieve depth-of-field. But this project was really fun to do and it gave me a better understanding of how lenses work. This is my shopping list:
JVC GZ-HD10 camcorder (AVCHD)
Opteka 55mm 10x HD Achromatic Macro Lens for SLR Camera
CPL Circular Polarizing Filter (remove glass, use rotatable ring for positioning your focusing screen while recording)
Macro Extension Tube Ring for Pentax K Mount Series (62 mm)
Several 62 mm 62mm UV Filters for locating the focusing screen at the exact distance from the lens (focal point).
Canon EOS 5D Replacement Type EE-A Focusing Screen
Any (d)slr lens with K-mount
To assemble these items together I used several step-up / step-down lens filter ring adapters and a male macro coupler reverse adapter ring.
I glued the focusing screen on a dia photo frame (24 x 36 mm). After cutting and gently shaping the frame I positioned it at the exact focal point in the tube.
Dust on your focusing screen will result in big ugly dots on your footage. To avoid this from happening I isolated the screen by placing UV filters on both sides of the screen.
