ETC 42550LT-5 25-to-50-Degree Zoom Lens Tube - Silver
ETC’s 42550LT is a 25°-50° zoom lens tube assembly—in Silver—designed to be used with ETC’s Source Four incandescent and LED ellipsoidal light engine bodies. ETC’s patented one hand zoom and focus operation makes adjusting the lens simple and quick. But the best part is that Source Four Zoom has all the advantages of the revolutionary fixed-focus Source Four: bright even field, cool beam, and amazing efficiency. The patented dichroic mirror means shutters and accessories stay cool, and drop-in accessories are interchangeable with fixed-focus Source Fours. Source Four Zoom gives you Source Four's crisp optics for excellent imaging and field quality.
