Stereo Front Extension Spacer

Unlike normal spacers, Extension Spacers attach directly to a Mercury Stereo camera without requiring a lensboard. They essentially extend the front of the camera by the stated distance. Further Base and/or Focus spacers then mount directly to the front of the Extension Spacer. This enables much longer camera configurations.

The Front Extension Spacer exists in several sizes. Each adds its nominal value to your camera's front extension.
