Marshall Electronics CS1150-8MP CS-Mount Varifocal Lens

The CS1150-8MP is an 8-megapixel 11-50mm varifocal zoom lens on a CS mount, rated for 4K/UHD imaging on cameras with up to a 1/1.7-inch sensor. The 11-to-50mm range lets an installer dial in the exact framing on site, from a wide 36.9 degrees horizontal at the short end down to a tight 8.8 degrees for reach, without swapping optics.

A bright F1.4 maximum aperture keeps the picture usable as light falls off, and DC auto iris lets the lens ride exposure automatically. Independent locking rings hold zoom and focus in place once set, so vibration or handling will not pull the framing off. Minimum focus distance is about 2.6 feet.
