Glad to see this thread has grown! Lots of good points made by everyone. For a bit about my background (for film) I shoot with a Pentax 67 outfit (4 lenses), a Pentacon Six outfit (3 lenses), a Mamiya C330 (2 lenses) a Fuji GW690, Nikon FA, F100, F5, F4, FM2 and FE, a few spotmatics and sp II's. I have a moderately good selection of good glass in all lines, all primes, well except for one 35-70 2.8 Nikon. I scan the 35mm stuff on a Dimage Scan Dual IV, so it's pretty easy for me to see on flickr what is scanned on a flat bed vs. a film scanner..so I try to rule that out when doing generalized photo comparisons. Also, I don't use autofocus at all and prefer older lenses and am especially fond of the look of my old SMC Takumars. I also shoot most of the time on tripod, although my goal for a 35mm pentax is a small rig that i can use for snaps around town hand held.
As I get older my criteria in equipment has shifted. I'm not a run and gunner (can't be with medium format) so I tend to take my time. The two parts of a camera that I REALLY value are the tactile response of the shutter release, and the focusing screen clarity and brightness. Next to that, the ability to do longish exposures without resorting to bulb is fairly important. Some of the shooting I do is down in the 2-6 second range.
Since I'm trying to settle on a good Pentax film body I ordered an LX from one of the big online retailers, it was defective (sticky shutter), ordered a 2nd one from them, also defective, although not as bad as the first, and they have a third one on the way to me now. I happened to buy a PZ1-p in excellent shape from someone tonight.
My initial thoughts are that I could fall in love with an LX if I felt I could rely on it to work properly. The camera really has a great "feel" to it and the viewfinder is very very good. FWIW, the Nikon FA viewfinder is maybe just a tad better or a tad worse, not totally sure yet...they are that close. All the autofocus cameras (PZ-1p, F100, F5) have pretty crappy screens to manual focus with. The F4 is sort of in the middle for an autofocus camera..decent focusing screen, not as good as the FA, but not terrible. The F4 is just too darn heavy though! When I look to 35mm I'm looking for light weight. If I'm going to carry a lot of weight I'll just carry some of the medium format gear..
The PZ-1P is a really nice camera to hold. What I hate is that the shutter release has zero tactile response (just like the F5, F100 and F4). I do like its super fast mirror blackout. It feels like a performance camera, but what's turning me off to it is I'm pretty sure I wouldn't be using my old takumars on it..it's too difficult to focus. I thought that I could manually focus them with audible beep when in focus, but unless I'm doing something wrong, it doesn't work that way. So, if I were an autofocus guy with lots of autofocus lenses the PZ-1P would be an awesome buy...but it's looking like I'm going to have to pony up the $$ for an LX to be happy..
