NanLite Adjustable Iris Diaphragm for Bowens Mount Projection Attachment

The iris adjusts so smoothly that dialing in the exact beam width for a spotlight effect feels almost instinctive. I’ve been using it with my Bowens projection attachment and the falloff control is noticeably cleaner than before.

Fiddling with the click-stops between f-stops is oddly satisfying—the iris snaps into place with a tactile precision that makes fine-tuning spot highlights feel almost surgical. The blades move uniformly with zero wobble, which is exactly what you want when shaping a tight beam onto a product shot.

Dialing the iris down to a tight spot for a background accent was effortless, and the click-stopped increments give you real precision without any fiddling. It locks in place solidly on the Bowens mount, so no drift mid-shoot. Exactly what I needed for controlling beam spill on close-up product shot
