I generally like my MZ-5: I wouldn't have minded if they'd left out the auto-rewind and left a rewind crank on there, cause I just don't like not being able to be positive the film is feeding, (Of all times to leave out the little wiggly red bars window that I never even notice on the old cameras.
)
The AF is OK if you take it on its own terms, no high-tech tracking or anything, here, but it's usually pretty positive, especially with the spot af button pressed. (at least with speedy lenses: I usually use fast primes for film. Most often, it just takes a beat. Especially if I don't forget that 'spot af' button, (particularly for MF confirmation.)
Street photo of walking people might well get ahead of you, in other words, but it's a pretty useful aid. I'm a little behind n my processing to rave about accuracy or anything, but it looks pretty good.
Manual focus isn't too hard, considering, at least with an OME-53 eyepiece on there. (These work and fit great, it led me to wonder if they were originally-designed for this series: it doesn't even vignette on me. Seems you get what the finder itself covers, anyway, so why not.
) It's no ME Super or LX that way, but manageable.
