"We believe that capturing the best image starts with the lens, but it’s also where the lens meets the sensor.” Hyperion CinePrime X is finely-tuned to match an all new 1/2.3 inch, 16MP CMOS sensor, for tack sharp, high frame rate HD video, and large fine detail still images. Prime X new sensor also features 33% lower power consumption for better battery life, higher sensitivity, better dynamic range, good lowlight performance with noise-free blacks, allowing you to shoot beautiful video up to 1080p 60 fps, 720p 120 fps, features Cinema 24/48, NTSC 30/60/120, & PAL 25/50 frame rates as well as 4K Ultra high definition time-lapse sequences and large still images at 16MP 4:3, 14MP 3:2, and 12MP 16:9 sizes.

Prime X has been supercharged… aside from optics & image, battery life is the most important function of any camera. Prime X was engineered around an ultra-high capacity, 1700 mAh battery, more than doubling usage up to an outstanding 3.5 hours on a single charge. That’s 200% more battery life than most competitors and lasts long enough to use all day for most stop and go activities. Prime X is microSDXC compatible up to 128GB allowing for extended recording sessions.

Our experience shooting on movie sets, live-streaming events, recording from within world-class racecars, on the helmets of top Motocross athletes, on Olympic Snowboarders, and with Gold Medal X Games athletes, the Prime X will deliver color accurate and cinematic quality video where others simply cannot.
