ETC Source Four Zoom 25-50 Degree 42550
ETC Source 4 Zoom 25-50 Degree 42550
With Source Four Zoom you only need one fixture for a variety of field angles. Plus, Source Four Zoom makes it easy: 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.
