My SMC Takumar 50mm f1.4 just came in (along with a M42-EOS adapter.) This is my first M42 lens. Boy, oh boy, what a jewel. I had intended to use the lens on my Canon EOS digital and film cameras, but now it's clear; I really _must_ pair it with a representative Pentax body. So, how about a SV? 1. I know the H3V is the U.S. import version of the same. Is there a reason to prefer one over the other? 2. I don't mind not having a in-camera meter, but MLU would be really nice. Does the SV have this feature? Is there a Pentax M42 mount camera that does? 3. I'm thinking about picking up the 500mm f4.5 next. Any problems using this with the SV/H3V?
