  1. For magnification bigger than 1:1, one should reverce the lens.

     

    <p>

     

    Rule of optics is simple: smaller object goes in front of 'rear

    element' of the lens, bigger object in front of 'front element'.

    Enlarging or any "normal" lens design assumes that smaller object

    (film) goes behind the 'rear element' of the lens and bigger object

    (ph.paper etc.) goes in front. It works for =ANY= magnification, e.g.

    if one doing macro grater than 1:1 (film size is bigger than the

    object) lens performs better in reverse position.

  2. Sinar. It's like Nikon or Hassy. You can always find a lot of them

    used. I use F2 in studio and fild. Frankly, it's not perfect for

    both. In studio, when doing makro 2:1 it's not rigid and precise like

    P2, but... I got sharp chromes. In fild, carry you camera with 6"

    rail in backpack and rail clamp attached to tripod. Setup takes 30

    sec. Anyway this camera is good compromise for studio&fild and get

    Horseman bag bellows.
