The JVC HZ-CA13U is a cine optical PL adapter. To enable the use of film lenses with the ProHD line of camcorders, JVC optical engineers have implemented an all-optical relay system that takes the image from the lens and converts it to the proper proportion of the camcorder imager, preserving the depth of field (DoF) and field of view characteristics. The result is an optical tool that enables the use of 16mm, Super16 and 35mm film lenses with a PL mount with the JVC ProHD series of camcorders.

The adapter will accommodate a wide range of lensing options, in particular the large implementation of existing 16mm film lenses. Super16mm and 35mm lenses can also be used with no vignetting in the image. As the construction is optics based there is minimal loss of light that is approximately 0.5f.

The 52mm focal plane is clearly marked as a groove on the barrel, and a 1/4" 20 screw hole at the base of the barrel allows the use of adapters for camera support systems.

Photographers will find the combination of JVC ProHD camcorders and the HZ-CA13U to be an unparalleled combination of lensing and operation flexibility for digital cinematography.

Q: 4. I don't see an ISO setting. There's a gain setting but I need to sync the settings to a light meter.

A: Traditionally, video cameras do not have ISO ratings because they didn't work like film cameras. Since there is no listed ISO for this camcorder, you will have to create your own ISO. Do to that: hang and evenly light a 18% grey card and fill the camera frame with grey. Set the camera to 0 gain, no filter, no shutter, auto exposure. Set your meter to 60th of a second or 30FPS with 180 degree shutter. Now dial the meter's ISO up and down until you match the camera's f/stop. That is your ISO. Over on the gain switch, 6db doubles that ISO number and the 12db quadruples it. I suspect you will want to only use 0db and on occasion go to 6db with 12db used only in emergency.
