Does anyone have suggestions for a focussing rail to enable fine forward/back movement of the camera on a tripod when doing macro work? I see there are many types, with wide price variations. I'm looking for something in the lower end of the price range while still getting good movement control and a solid base for the camera - if that's possible. I need something for about 5 pounds of camera/lens. Please tell me why you'd choose one over another.
Thanks in advance.
