Yes the Kiev rangefinders can mount all contax rangefinder Zeiss lens, at least the pre war( certainly not the G series rangefinders), it's basically the same design as the contax II. As for the zorki they use Leica Screw mount lenses, maybe a wider choice of lenses if you really need a lot of them.
For me the Kiev/contax mount lens choice Is sufficient as I only shoot 35mm and 50mm. I can't say the Kiev viewfinder would be good for eyeglasses wearer, but I find it rather squinty but liveable.
