Engineered for performance in all conditions, the chassis is made of a lightweight and strong polycarbonate material wrapped in a slip-resistant armoring, with a rubberized and textured zoom collar and focus wheel make adjustments fast and easy, even when wearing gloves. The optical tube is nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. To increase your mounting options, the TSN-501 comes outfitted with both a 1/4″-20 and 3/8″-16 tripod attachment — making it compatible with most photo, video, and field tripods on the market.
