  1. Re: LF Macro Lens

    I don't think so. I believe that bellows extension is directly a function of the distance between the lens plane and the film plane.
  2. Re: LF Macro Lens

    Huh. I wouldn't have thought of that. By any chance do you have experience with these? What is the principle behind needing less bellows extension than normal lens for similar magnification? I assume...
  3. Re: LF Macro Lens

    Thanx. Performance issues weren't something I was trying to solve for unfortunately. The problem I was trying to solve for is that I primarily shoot portraits indoor using natural light. In order to...
  4. LF Macro Lens (...and understanding bellows extension for tele lenses)

    Just wanting to confirm here that I understand how these lenses work. In general, will using a LF macro lens require less bellows extension than a normal lens given any magnification ratio?

    thanx...

    Why would you enlarge to 1x? Seems stupid. Why not contract print????

    Also, when you guys are all talking about better, best, etc. What are you talking about?????
