Some of my friends of the large format community know I'm collecting special types of lenses, esp. portraiture- and soft focus lenses. One more modern design lens is the Fujinon 180 SF, which is made for 4×5" format. It's similar to better known Imagon but not the same. The perforated aperture blades of the Fujinon SF are placed between front element and shutter.
On my last shooting with Halyna I tested it with my Linhof Master Technika.
Ilford FP4+, no postwork (only dust removing in PS). Small blade (red dot) at f=5,6.
