Adjustable iris diaphragm controls beam diameter on the MG1200BI spotlight mount for precise light shaping

  • Precise beam sizing for creative lighting control

  • Removable design allows quick changes during a shoot

Precise Beam Control

The Godox GP-ID Iris Diaphragm fits the MG1200BI spotlight mount and adjusts the projected beam diameter with fine increments. It slots into the dedicated iris port of the projection attachment for secure, repeatable positioning. Photographers and videographers gain exact control over circle size and edge definition for creative lighting.

Creative Pattern Shaping

The removable iris lets operators change aperture settings quickly while the unit stays mounted, switching between sharp spotlights and soft gradients without tools. This flexibility supports tabletop product work, portrait accents and narrative set lighting from a single fixture. The accessory expands the MG1200BI’s projection capabilities without adding separate modifiers.

Professional Build and Mounting

High-grade materials withstand daily studio handling and frequent aperture changes. The G-Mount interface locks the diaphragm firmly in place, preventing light spill and maintaining alignment during repositioning. Its compact form adds negligible bulk to the projection head, keeping the rig balanced on stands or overhead grids.

Questions about this item

Does the iris diaphragm itself need periodic cleaning or blade lubrication?

The iris diaphragm is a mechanical blade assembly with no motor or electronics; occasional dust removal with a soft brush is the only maintenance it requires.

What stops me from closing the iris blades down to a pinhole during a long shoot?

The blades are limited by their own mechanical stop at minimum aperture; there is no thermal or electronic limit that intervenes first.

Does the diaphragm add any fan noise, heat or power draw when the MG1200BI runs continuously?

It is a passive metal component with no fan, motor or electrical connection, so it contributes zero noise, heat or power consumption.
