Yes the 1:1 vf makes a big difference with longer focal lengths.
Never owned a re-issue, but owned and used an original S3 and several S2 over a two year period. Light and compact, easy travel cameras, but the rangefinder patch on the S3 was a bit more "diluted" or "faded," even after cleaning the mirrors. Useable, but not as much fun to use as the S2. My understanding is that the S3 has a non-tinted viewfinder, which results in a less contrasty rangefinder patch. I think the same is true for the re-issue model. You either love it or hate it, I suppose.
Handled an old SP once but the patch was faded to the point of uselessness. Nikon rangefinder guys will tell you that most of them can be cleaned up.
Absolutely loved the focusing wheel, whether it be Nikon or Contax. Don't have to use it, but it allows one-handed shooting once the aperture and shutter speed is set.
No longer have any Nikon rangefinders. Fun shooting experience though. The reissue models seem like a good value these days.
Good luck on your decision.
The 50mm 1.4 lens is poor at 1.4, ok at f2, excellent at 2.8 and down. The 85 f2 is a tank but a good performer. The 35mm f2.5 is excellent.
Disagree. I prefer the indistinct patch of the Nikons over the sharp rectangle of Leicas. YMMV.
Why? Just by your description that doesn't sound like the right choice!
