TS Optics 0.3mm stainless steel fine tuning ring for M48 filterthread
Fine tuning rings from TS Optics are a real problem solutionThey
allow fine adjustment of the distance with much higher precision than
with M48 extension tubes. Furthermore, in most cases the stability is
higher than with variable extension tubes.
In opposite to plastic
tuning rings, a clean support is always guaranteed with metal rings.
They can always be removed, too, even at low temperatures.
Applications of fine tuning rings- Optimizing the distance between camera and corrector
- Fine
tuning of extremely short distances of only a few millimeters, where
extension tubes are too long, due to their construction
- Male
threads which are too long can be bridged, so that they are not a
drawback anymore (like with the TS filter quick changer, where the male
thread would block the drawer)
- Especially fine threads tend to
jam, they seize, and one cannot screw them apart again. Often, the reason for
this are improperly made last thread turns. Through using the fine
tuning ring, these thread turns are excluded, the bearing gets more
proper.
