The best RED Pro Zoom lens available, the final version; 17-50mm MKII T2.9 / f2.8 PL mount manual zoom lens designed for DIGITAL CINEMA production but just as happy on a 35mm film camera. It is designed for almost every shooting environment with a 17-50mm zoom range, this lens is great for wide-angle to portrait shots. A useful timesaver on a RED camera is the ability to lower the resolution to 5K/4K or 3K and crop-in on the sensor, enabling tighter shots with this 17-50mm MK2 RED Pro Zoom lens.
