Samsung SLA-550DA - CCTV lens - 5 mm - 50 mm

A varifocal lens allows the installer to adjust the field of view (zoom) to meet the needs of the application. Unlike a motorized zoom lens, a varifocal lens cannot be remotely adjusted. The advantage of the varifocal is that it is much lower cost than a zoom lens. The SLA series of varifocal lenses is a high quality IR corrected auto iris lens that is well suited for use with the high resolution Samsung Techwin cameras. It features high optical performance without the ghosting or aberrations found in or binary varifocal lenses.
