<\/span>What is a macro focusing rail and how does it work?<\/strong><\/span><\/h2>\n\n\n\n

A macro focusing rail, also referred to as a macro slider or a focusing rack, is a device used to precisely control the camera position during high-magnification photography work. The typical geared macro slider is a device comprising of a fixed track or base and a movable platform that is moved along the track using the gear knob. Gear mechanisms in macro focusing rails are either rack and pinion or lead-screw types. This construction allows for precise measured movement while retaining the necessary stability of the rig. <\/p>\n\n\n\n

As its name implies, a macro focusing slider is predominantly used in high-magnification imaging, for example in scientific or product photography. Some photography techniques, like focus stacking in particular, benefit greatly from the control these devices deliver. <\/p>\n\n\n\n

They can be successfully used in video too, especially when shooting close ups, making stop motion animation or timelapse sequences. A focusing rail can not, however, replace a dedicated video slider, as it is not designed to provide the same type of movement. <\/p>\n\n\n\n

In addition to focusing and composition, a rack can also be used as a balancing device for heavy rigs, or as way to position the nodal point in panoramic photography. You can learn more about the alternative uses of these devices in our dedicated section below.
