The Kirk FR-2 Focusing Rail is a precise focusing stage designed to permit fine tuning of camera-to-subject positioning in order to achieve exacting focus. The rail is driven by a 4.25″ stainless steel lead screw, with a pitch of 5/16″-24, that enables critical positioning at a rate of 0.042″ per revolution. Fine focusing is controlled by one of two knobs located at the ends of the rail or, for larger adjustments, a stage release lever permits faster, less restricted movement. Some of the features include:
- Precise Camera-to-Subject Focusing
- Adjustment Range: 4.25″
- Stage Travel Per Revolution: 0.042″
- Knob-Controlled Fine Adjustments
- Release Lever for Large Adjustments
- 360°-Rotating QR Mount
- Arca-Type Dovetail on Base of Rail
- Compatible with Arca-Type Camera Plates
