Since you said big bright viewfinder, then there is no bigger or brighter then the Pentax LX by any brand or model ever. Fortunately, Pentax also provided the most eye relief as well since they gave the LX the most extensive lineup of viewfinder accessories . . .
You want all metal as well as relatively low weight and size . . . well that again would be the Pentax LX because relative to its peers it is smaller and lighter while being "all metal" and offering the most manual features if the batteries die as all shutter speeds - sync and above, are available. Excellent build quality - selective rain testing from assembly line as it is also the only sealed and weatherproof camera among it's peers. Titanium shutters so you won't have any concern of ever pointing it at the sun in mirror lock up mode unlike all modern cameras.
And for the pièce de résistance, you want excellent metering, well there is no other camera ever made - past or present, film or digital, by any other brand that can meter for as long as it takes to get a proper exposure or batteries die.
This one of the Hoover Dam at night on Kodak Ektar 100 that lasted over 45 minutes . . .
I've tested all my aperture priority capable cameras of different brands and models and none can meter long exposures of only many minutes consistently. And by very long exposure, I have tested both of my LXs to consistently meter up to many hours long which is of course recommended by the various films datasheets to verify reciprocity failure. To date, I have yet to experience any film reciprocity failures with any of the color negatives I have used . . .
Dear LesDMess...
I finally got myself a Pentax LX, after years of reading you extolling the virtues of the mighty LX.
My short comparison to the previous pro SLRs i liked: Canon New F-1, F-1 and Nikon F3, F2SB. But in particular, compared to the New F-1, since it was my pick for "favorite pro 35mm SLR":
Big Pros
- Significantly lighter and smaller. It really feels light and nimble, for a pro machine.
- Very ergonomic, feels great in the hand
- Exposure compensation warning (something the F3 and F-1N don't have)
- TTL OTF Flash metering
Pros
- Shutter sound slightly quieter than my F-1N cameras.
- 1/2000 to X (plus B) speeds are mechanical all the time, while the F-1N requires you to remove the battery to enable mechanical backup speeds.
- Double-exposure doesn't advance the film counter
- Film rewinding makes the counter go down (a really useful feature)
- TTL OTF metering
- Provision for vertical or horizontal strap
Cons
- Number one: Viewfinder info (shutter speed numbers and flags) intrudes into the framing area. This is the only professional 35mm camera I know of that does this. I find this annoying, doesn't help for composing pictures.
- No, the viewfinder isn't better than the one in my Canon F-1N cameras. My canons have a clearer viewfinder, probably due to the Laser Matte screens. And note that I have thoroughly cleaned the screen and condenser in the LX before judging.
- F-stop displayed above via a separate window, as in the Nikon FE. And relies on ambient illumination to be seen. On the F-1N all the following information can be glanced at once without moving your eye: Selected f-stop, suggested f-stop, speed, maximum f-stop.
- Viewfinder frame seems slightly curved, not completely rectangular, probably due to the optics on the FA-1 finder. I don't like this.
- Slow, cumbersome screen change. The screen is changed as in an amateur camera like the Canon AE-1P or Nikon FE or Pentax MX. Instead of the easy screen change of the F-1N and Nikon F3. You really need to be sitting down on a bench with tweezers to do the screen change!
- Can't vary metering pattern
Lesser cons:
- No battery tester (the F-1N shows you the battery level and it will tell you how healthy is your batt.)
- TTL OTF metering means the auto speed can differ a bit from the meter suggested speed.
- TTL OTF metering also means film should be loaded to test auto speeds.
- TTL OTF metering pattern probably differs from the viewing-time metering system's pattern.
- Slower battery change procedure
- Film path doesn't have the sophistication of the F-1N. The Canon has a film cartridge stabilizer, plus two rollers that press film against the advance sprocket. And the film is rolled following its natural curl. The Pentax has none of this, no rollers, nothing.
All in all is a camera that I think I'm going to like a lot, however it's not the "F-1N killer" i was expecting.
