Was just lookng at my Schneider enlarger lenses and my Componar 4.5/75 only has four blades so a square iris, however my Comparon 4/50 has 15 blades. No idea why the difference, they are both tiny C mount lenses. The Comparon must be like a watch mechanism inside with such a complicated aperture packed into such a tiny lens...
