        mid-70's, has shown infinity not coming in until f11.  It's a point I   
        always try to impress on new users of Wideluxes and something we always 
        had trouble with while renting cameras.  It was also a big reason I was 
        excited about the newer Horizon and Noblex cameras, the ability to shoot
        landscapes at "wider open" apertures.
        Don't know about your reference to IR, infinity and f5.6, but I know a  
        number of people shooting IR successfully with Wideluxes for many years 
        now.  Geir Jordahl in the Bay Area of California would be the first one 
        that comes to mind.  A very successful user of IR film in a Widelux for 
        a long time now.

Quite correct, I've seen MANY truly excellent IR images taken by Geir with many 
Widelux cameras he's had over the years.  Interesting, however, is that the 
Noblex 35 didn't work for him for IR images.  It seems the Noblex is not IR 
light tight.  Geir tried several cameras all with the same results.  He even 
tried lining the camera back (where he suspected it was leaking) with lead foil 
to no avail.
