Lots of suggestions.
I'm a little lost, but to be fair, my questions were open-ended.
The only SLR body/lens that I have right now is a Leicaflex with a 50mm f2.0
Summicron. I like it very much, but the 50/1.4 Summilux is too pricey, and so I'm looking for a faster, cheaper alternative to compliment this camera. I love everything about this camera. The size, the quality, the viewfinder, but the lens is sometimes too slow.
Lens:
I'm looking for a manual focus 50mm-58mm f1.2-f1.4 lens. I don't have a budget per se, but I would feel uncomfortable spending more than $500 on a lens. I'm not sure how I feel about f1.2 lenses... I've never owned one but I would expect the slower counterparts to perform better, all things equal. The lens doesn't have to be clinical sharp, so 70's-80's lenses are most probably fine. Auto-focus (sigma) is not an option.
Body:
I'm looking for a body that is great for manual focusing. To me, ths means a contrasty viewfinder and a plain matte screen. I don't like focusing aids. All-mechanical is a bonus. A bigger/heftier camera is also a bonus.
Questions
Pentax
1. Do the K, M, and A lenses work on every bayonet body? Like the KX and the MX.
2. Are plain matte screens easy to find? Are they available on the spotmatic.
3. Which models have the best viewfinder?
With that said, I'm leaning towards a Nikon F2 or F3 with a 50mm f1.4/f1.2 or a 58mm f1.4 lens, a Contax RTS I/II with a 50mm f1.4 lens, or a Pentax KX/MX with a 50mm f1.2 K mount or some 50mm f1.4 lens. Nothing wrong with Olympus or Minolta but I don't feel that their cameras fit me. Konica fascinates me, but not having an interchangeable focusing screens (for a plain matte) is a deal breaker (unless I'm mistaken and they do have models with interchangeable focusing screens) since there are many other camera options that do.
