I bought my wife a Minolta Maxxum auto-everything camera in the late 1990s. It had tremendous shutter lag and missed the focus more than half the time. I don't remember the model but I think it was 450 or 550... (we sold it a few years later since she was so disappointed she neglected to use it)
It was compact enough (certainly not OM1 size but fair enough).
If I were looking I would want something that focuses better than that Minolta.
AF on the 5 is excellent, though the in-body motor is not the gruntiest so it's slow with huge lenses (like my 100-300 f/4) attached. It's not in Dynax 7/9 or Nikon F6 territory but you don't have to carry 10 pounds of magnesium and a small nuclear reactor to power it either.
Asserting that Minolta AF is all crap because the base-model thing you bought was, is specious. Nikon AF must be crap too because my old FT really can't hack it!
I'm looking for a compact 35mm, full frame slr with auto focus. Comparable to OM-? bodies. Was there anything like this ever made? My vision is making it very difficult to use manual focus. I have an F100, but would like something considerably smaller. N80 seems too large. Rangefinder's won't work for me either. I've tried Bessa R2 & R2a. Not interested in P&S or Hexar AF. Any input is appreciated.
The OP may be chasing rainbows. I wouldn't describe any of the cameras listed as compact (can't speak for the Pentax, haven't measured one). Many are light, especially with a 50mm instead of a kit zoom but compact? Certainly not OM1 style.
