I got a Hexar AF earlier this year. It came to me unexpectedly and non-functional, and frankly I wasn't sure if I would like it (assuming I could repair it, which I did), given my preference for manual, non-battery-dependent cameras. I've been surprisingly pleased with it. The Program mode works essentially as a smart aperture priority mode, which I've found the most useful, but for street work it's very easy to lock in the same settings I normally use on maunal cameras and shoot similarly. I haven't encountered problems with accurately metering for film speeds from 50 to 1600.
Trying to use the camera in full Manual mode all the time, however, seems to me an exercise in frustration. If I'm in a situation where I want to use varied manual settings, I'll bring another camera. Like all tools, the Hexar AF is better suited to some tasks than to others.
