I'm pretty sure that the Kiev is based on the Contax II mechanism so it should work, but I really don't know how reliable their timers are. I guess owners should be wary if they have not been serviced in some time. Like I said, I have only done that with my own camera a few times but it was a handy little technique when I needed it.
The Kiev 4a is , the others are based on the Hasselblad 1600 .
It's not the basic design that's the issue , it's quality control that's the issue .
Friday afternoons and Monday morning cameras being the worst!
Basically not being very well put together and a grease left over in the factory from building tanks to lubricate them is what gives the problems . When it dries out , it becomes quite solid .
A good service would prevent these problems .
Most haven't been serviced.
It's not just FSU cameras that can run into problems when using the mechanical self timer release .
I've come across Japanese ones as well .
The only self release timers I use are on electronically controlled ones , unless the cameras I'm using have been serviced.
