4K Adventure. Pocket Size. 43.5g. Waterproof. F/1.7 aperture. Shoots in 4K. 🎬 True 4K/30fps Cinema-quality 3840×2160 resolution with H.265 compression for crisp footage and smaller file sizes. HDR mode available. 💧 IP65 Waterproof Splash, rain, and dust resistant bare. Use with the included protective case for depths up to 10m — pool, ocean, or white water. 🌙 F/1.7 Bright Aperture A wide-open F/1.7 lens lets in maximum light for sharper footage in low-light and evening conditions. 📍 Thumb-Size Portability At just 58×19mm and 43.5g, the XCAM 4K slips into any pocket, clips to a helmet or bag, and goes wherever you go. 4K Adventure, Pocket Size True 4K at 30fps, a bright F/1.7 lens and an IP65 waterproof body — all in a 43.5g thumb-sized camera you can clip on and forget. Capture the trail, the dive or the ride, then share it straight from your phone. Cinematic 4K Detail A 1/3-inch sensor and F/1.7 lens capture true 4K at 30fps — crisp, vivid footage of every adventure, ready to share straight from the app. Rain, Splash, Repeat An IP65-rated body shrugs off rain, sweat and splashes, and a protective case takes it 5–10m underwater — film where ordinary cameras can't go. Brilliant in Low Light A bright F/1.7 aperture pulls in more light, so dawn rides and dim interiors come out clean instead of grainy. Disappears in a Pocket At 43.5g and barely bigger than a key fob, the 4K clips to a collar, a strap or a cap and goes wherever you do — you'll forget it's there. Clips, Magnets, Mounts Magnetic backing, clips and a back-clip design snap it to helmets, bikes, bags and metal surfaces in a second — hands-free from any angle. Room for Every Moment Record to microSD cards up to 512GB — hours of 4K footage on board, never missing a single frame. Perfect For Built for cycling, hiking, swimming, snow sports, travel vlogging, and any outdoor activity where quality and portability both matter.
