Some of my cameras, an Ansco Viking, Yashica A, and Crown Graphic, use a continuous ring/dial for adjusting shutter speed and aperture (meaning no rigid stops).
If I place the dial between two shutter speeds, 1/100 and 1/200 for example, will it give me a shutter speed of approximately 1/150 or is it not meant to be used at any points between the markings?
The shutter will still fire at these points between (although I'm not certain how accurately) but I just want to make sure that using these between points will not damage the shutter mechanism in any way before I actually use the camera in such a way.
