[edit] Shutter drive and controls

I added the citation needed because this information was contradicted by someone who is knowledgeable from Rangefinderforum.com: Discussion

From the control aspect, there are these different kinds of shutter systems (I have simplified things for the sake of brevity):

• Purely mechanical -- A spring is released mechanically from the shutter release button that drives the curtain, and the curtain speed is controlled mechanically.

• Mechanical hybrid -- A spring is released mechanically from the shutter release button that drives the curtain, and the curtain speed is controlled electronically.

• Electrical hybrid -- A spring is released electrically from the shutter release button, which is really a switch, and naturally the curtain speed is controlled electronically.

• Purely electrical -- Electromagnetics drive the curtain and is triggered by the shutter release button, which is a misnomer in this case as it is simply a switch for a horizontal motor.

Obviously you can substitute mechanical leaf shutter for curtain, and the "iris" type leaf shutters are ignored here; they are common in rangefinders and appeared in a few SLRs such as the Voitlander Bessamatic.

I believe that my X-700 has an eltromagnetically driven curtain making it purely electrical, but I don't know for sure (that is without dissecting it).
