To the OP:
These days, if I were you, I would get hold of a (very) decent Medium format camera (Hasselblad or a Rolleiflex 2.8F) and shoot medium format.
If you are used to the clean nature and impeccable quality of digital, then medium format is probably the only thing that will satisfy you properly.
Well, unless you plan to shoot Tmax 100, Acros 100 or another bigger brand 100 ISO film or Velvia 50 slides.
35mm is practical, but it does tend to have a few drawbacks like:
- Dust more apparent on scans.
- Obviously grain and resolution.
- Quality does not equivalent modern digital high-end cameras (it really doesn't, despite what people might claim).
- 36 frames is too much anyway, unless you are on holiday or shooting an event, it's more to scan and you need to shoot longer to use up the film....which may be a challenge if you are going to "make photographs" and not snapshots.
- Leica schmeica.....seriously, when you look at it from a different standpoint, it's just a light-tight jewelery box with a fancy logo, it's the glass that matters, you can use Leica-glass on IE a Voigtländer R3M. (Yes, I know I am pissing of the Leica-boys with this, but it doesn't make it any less true).
If you were to go for 35mm anyway, then go for a proper high-end Nikon or Canon Autofocus SLR and quality optics, so your shots are in focus and sharp and with good exposure.
I shoot most formats from 35mm up to 6*9, rangefinders, SLR's, TLR's.....russian, japanese, German, whatever....and I also shoot digital and I scan and use the darkroom for my analog work.
There are so many other nice things to be had, beside "a leica". 🙂
