Hi all,

I am a fairly experienced 35mm and digital photographer looking to move into LF. My budget is low and I would like to spend as little money as possible. I have an idea of building a point and shoot style 4x5 camera (based on a design like this http://www.flickr.com/photos/bensyve...ith/359107636/). I have a few questions.
-How do you recommend I mount the lens and shutter in the material that I am using? Would it be easier to just attach a lens board?
-How far must the lens be from the film plane to achieve infinity focus?
-Do I need a helical mount? Can someone explain the purpose of one?

One more question that I just have in general about LF gear is do all lenses come with a shutter? My understanding is that it is kind of one thing, but I just wanted to confirm.

I apologize for all of the newbie questions and appreciate your help,
Evan
