With a zoom you only need one fixture to achieve a variety of field angles, and with Source Four Zoom it's easy too.
ETC's patented one-handed zoom operation makes adjustments quick, simple and safe. Technicians can focus with one hand and hold the ladder with the other. And the lens tube door provides quick and easy access when you want to clean the lens assembly (tool-free!).
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. Rated up to 750W, Source Four Zoom gives you Source Four's crisp optics for excellent imaging and field quality.
