I was using FED that was stuck on 1 speed [1/50th] so I just jiggled the aperture to suit. Good results too. The Kievs i have I only use on hyperfocal with wide lens - otherwise you might as well use a P&S - surely.
The Zorki 6 I have has a integral dioptre and can be easily adjusted to suit my eyes as I wear glasses too - except when using the Zorki.
