I have an idea, but no idea if it'l fit what i want. got a camare with 58 mm thread on the lens for mounting stuff like filters etc..
Now there is a microscope adapter M42x0.75 thread to 23,2 to fit the microscope shaft.. All fine
But now i have to stepdown the 58mm lens to 42mm, this aint a problem also.
But my question is..
Will it fit is it the same thread, can't actualy find any thread specs on those stepdown rings.
It's this ring which is only specified in MM but not type of thread.
