Having owned and used two examples of the camera I like to think of as having "influenced" the creation of the M7 (Konica Hexar RF), I'll say this much about the M7, which I have handled:
- If anything, the M7's shutter should be more reliable than the M6's on account of the lower parts-count for the electronic shutter. There's always the issue of the electronics themselves, but can think of precious few cameras with electronic shutters that gave out until perhaps twenty years out at least. There are exceptions, of course, but there are legions of mechanical-shutter'd cameras that made the D.L. in the same time period, if not earlier.
- Shutter-speed accuracy: not much guess-work here: 1/500 sec. on an M7 should remain 1/500 sec. for as long as the thing holds out. One less thing to have tweaked every so often. Shoot slide film without fear.
- Battery-dependent? Easy to carry a spare set. Certainly easier than dealing with anything digital, which require several bits (spare battery plus charging apparatus), especially in remote locations. Truly a non-issue.
- Back to that shutter. What's quieter than a typical Leica M at slow shutter speeds? A Leica M7, that's what.
- Motor drive: Okay, this is where the Hex has a leg up, IMO, since they managed to build it into the body, but not make it bigger than a late-model M's favor is the ability to work sans motor, which is more quiet, but bulkier (and no motorized rewind, but you can deal with that).
- AE. I don't care what anyone says, an M7 (and Hexar) simply gives you a choice: AE when things are happening crazy-fast, and fully metered manual, when you feel the need for it. The M7 is not taking anything away from you here; unlike multi-mode-happy SLRs, you get one Auto mode plus a truly useful Manual mode, in uncluttered form that doesn't obfuscate.
Given the bucks, I'd probably have an M7 as Camera #3 to my Hexars as a non-motorized option. As things stand, I'll be lucky to get an ZI. But I'm betting you'll be crazy-happy with an M7. Buy it, then go forth and photograph.
