Intermediate values - what's between the speed dots : LUSENET : Minox Photography : One Thread

On the various Minox models it's possible to set the shutter speed BETWEEN the dots. In my IIIs manual it states that "intermediate values may be selected" - is this setting one value, or is it "analog" similar to the distance setting?

The speed dials on many Minox models are continuos linearly on the speed dial. For instance, speed in the middle of 1/50 and 1/100 is 1/75.

A reader of Minox FAQ tested his Minox B camera shutter with laser beam pointing at the lens, then measured the reflected light with a photosensor and registered the response on an oscilloscope. His results are interesing:
  1. At 1/500 2.18 millisecond= 1/460 sec
  2. 1/750 sec 1.51 msec = 1/660 sec
  3. 1/1000 sec 1.11 msec = 1/900 sec

  1. The Minox B shutter is quite accurate.
  2. In between 1/500 and 1/1000, the shutter indeed registered intermediate speed.
