Macro Focus Rail III
When close-ups are to be made with a large magnification (5x or more), focusing can easily be accomplished by using the Macro Focus Rail III for precisely setting the position of the lens, or extension tube. This device is also useful for making close-ups with a predetermined magnification. (If the lens alone is moved for focusing, it causes a change in magnification.) Maximum travel is 2.25".
