Izu kenru lens
This famous jap. photographer use a Deardorff 14x20 camera(probably the only one ever made on this format).
I could see on a mag time ago a pic of hime with his equipment , he use an old Kodak lens (maybe) .In some pictures it's seems that the lens is covering the format and in another pictures not (vignetting ) as you can see on his very nice web-site:
I'm just curious to know what kind of lens he uses (I don't wnat to bother him asking directly...I'm tooo shy..eh!eh!)
