Hi! As an act of randomness, I bought a Zenit-12 XP with Helios-44 58/2.8 lens since the cheap price and heavy, all-metal construction appealed to me. I also thought it would be nice to have a M42 body since I already have some M42 lenses anyway. Now I'm generally been pretty satisfied with the camera body for everyday shooting except for the lack of slow shutter speeds of course, but I knew that already... however there is one problem: The light meter is always on! It drained my fresh batteries in around 3 days which is when I noticed this, though I *think* that at the beginning the meter used to activate only when I half-pressed the shutter release. Any idea how to solve this, is there a known trick (except "remove batteries")? And what is the purpose of the T and V settings on the shutter release button?
