Hallo Monz - I hope Mukel will allow me to answer this, as I have a funny picture to hand
🙂
In an attempt to avoid infringing Leitz patents, the Contax, the original basis of the Kiev, does things rather differently, which in turn means that you hold the camera in a slightly different way. Essentially the middle finger of the right hand is braced below the rangefinder window/focusing wheel, which are situated in an extension of the faceplate along the top "left" of the camera (seen from the front). The forefinger then slips above the faceplate to operate the focusing wheel.
This sounds more complicated than it really is - it is simply the natural way to hold a Contax. The result is a very stable grip on the camera.
I enclose a comparative (and somewhat dubious
🙂 ) .demonstration of the holds by the great H.S. Newcombe - a Leica enthusiast (and it shows!)
Incidentally, Monz - an excellent introduction to the Kiev here:
