I can't say the FA exposes less reliably than my other compact F's, although the rather crude matrix metering brings an element of unpredictability with, totally different from f.i. the D700's matrix metering, which appears idiot proof (the idiot being me). I was making some outdoor portraits last night in low light, standing format, and found myself wondering what the FA's exposure meter would make of it. I decided to stop worrying and let Tri-X's latitude take care of it.
I do find my FA's shutter sound a bit annoying; as if a spring is loose. The other ones sound more solid, and the FM3A's additional mirror damping is noticeable.
