Kirk FR-2 Overview

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.

Mounted atop the focusing rail is a 2.5" quick release mount, which can rotate up to 360° in 90° intervals. This mount accepts Arca-style quick release plates for easily attaching both cameras and collared lenses. Extending the entire base of the focusing rail is an Arca-style dovetail with three 1/4"-20 mounts. A custom made Optech neoprene storage pouch provides added protection to your focusing rail when transported to your location or when not in use.

All parts of the rail are CNC-machined from 6061-T6 aluminum alloy and stainless steel.

Can this rail be used just as a nodal rail to prevent parallax for panoramas and how long if a lens works. I would like to use it for both pano and macro shots
Asked by: Anonymous
Yes, one can use the Kirk FR-2 Focusing Rail as a nodal rail, to prevent parralex for panorama, and can be used for macro and panorama shots.

question

Does the Kirk FR-2 focusing rail come with a plate or are they sold separately ? Also is the PZ-148 the one I need for a Canon 5dsr ?
Asked by: Robert
It has an ARCA-Swiss mount so pretty much any ARCA-Swiss plate should work. I typically use one from Spider since I use a Spider holster with my Nikon.

question

how does the fr-2 mount to a tripod?
Asked by: Dale R.
The FR-2 focusing rail has a standard Arca-Swiss fitting. The grooves extend the full length of the base and provided you have a head with an Arca-Swiss fitting it can be attached at any point along the base.

question

Is there enough clearance such that if a collared macro lens is advanced down the rail with the camera oriented vertically it will not be blocked by or contact the rail itself? Also if the camera is oriented or tilted downwards would the rail advance by gravity or is the mechanism tight enough that it wouldn't do that?
Asked by: Howard
Can't help on the first part. The rail will hold it's position when tilted down.

question

Is it possible to add a second Kirk FR-2 to allow for both X and Y focusing movement? If so, how stable is it? It looks like the bottom plate is Arca-style and so could mount on top of another, but wanted to confirm. Thanks!
Asked by: Al A.
Although I have not done that myself, but technically the more you add-on to it, the more it's going to affect the steadiness. Don't you agree?

question

can i use focus stacking with this ? if i use phase one afd+ , 120macro.
Asked by: Dae Wook
Yes, you can use this to track the camera/lens to stack photos. It will be done by hand, which could take a while depending on how many shots you plan to stack!
