Re: Enlarger lens...UK

[Elgenper <elgenper@xxxxxxxxxxxx>]

The condenser is a large single or double lens above the neg carrier 
that collects the light from the bulb and sends it through the neg into 
the  enlarger lens.  It has to a) be big enough to cover the entire neg 
(easy to check), and b) have a focal length approximately equal to its 
distance from the enlarger lens (harder to check, but if a) is 
satisfied, b) usually is, too).

In most "consumer grade" enlargers you have to switch condensers when 
changing format (and after a session of printing, they´re HOT!).  Some 
more "professional" units solve the problem the way Pablo suggests: by 
moving the condenser up or down within the housing (much faster).  I 
don´t know about Kaisers, but Pablo seems to know them better.

I think we´ve covered the major points by now, at least pertaining to 
printing 120  ;-)
