Self-Centering Lens Mount, Medium, Universal

Ealing's Self-Centering Adjustable Lens Holder holds lenses up to 51 mm in diameter. The three arms of the lens holder are retracted by pinching together the two external levers on the top of the mount against spring pressure. When released, the three arms grip the lens in soft v-grooved jaws, automatically centering the lens within the holder. This device is particularly valuable when lenses of different diameters are being used interchangeably as repeated centering is unnecessary.
The mount comes with both an 8-32 and M4 mounting hole for mounting to a Half- Inch Post or Pedestal Pillar (sold separately).
