    I have no idea when it comes to darkroom equipment, so please help me out.

    I found this thing:
    http://www.thephotoforum.com/forum/showthread.php?t=49396

    Question 1:
    I want to put a 50mm on it, but if my calculation is correct, I will not be able to focus except for very small prints.

    This calls for a flat lensboard. Can I improvise? What's the part number? Where can I get one cheap?

    Question 2:
    The condenser is a variable condenser head for 4*5 film. If I use it for 35mm film, does it mean that I'm losing 95% of the light? I can adjust one of the lenses to different heights to suit different lenses.

    Question3:
    Is the rodenstock omegatron 135mm f/4.5 a good lens? It looks like a four element design.

    Thanks everybody!

    Thank you for the links

    I'm still confused about the head. Do I need another lens or a head to print 35mm efficiently?

    The 135mm lens is for printing 5x4.
    Enlarging lenses are the same size for a given film format as the standard camera lens for said format.
    You will need to use a 50mm EL for 35mm negs. You should also get the right carrier and condenser to avoid problems and get it working efficiently.
    The enlarger should cope with 35mm OK then.
