This is a collection of focusing aid for different diameters of lenses / focusser rings.

In astrophotography or macro photography it is essential to focus as precise as possible. By turning the focus ring on DSLR lenses by hand, it is quite difficult to lock down on the best focus possible (most likely you will be able to turn the focus ring by a degree precision). With this tool attached, it is possible to get really precise focus, as you will be turning a screw on one of the two parts. Whic
