Ever wanted to snap photos from two cameras at once without missing a beat? The Fotodiox Stereo Shutter Button makes it easy to trigger two cameras simultaneously with zero lag. Perfect for stereo imaging, dual video recording, or testing different camera models side-by-side, this handy remote trigger lets you capture synchronized shots effortlessly. Featuring two 2.5mm (3/32") female TRS stereo jacks, it works with any camera that supports remote triggering via those cables (cables sold separately). The shutter lock slider lets you hold the shutter open for long bulb exposures or continuous shots, making it ideal for creative photography techniques. Lightweight and compact, it fits right in your camera bag and is ready to go wherever your shoots take you. Included is the remote shutter button itself, while you'll need to supply your own 2.5mm TRS stereo cables for each camera. Plus, you get peace of mind with a limited 2-year warranty from Fotodiox Inc. Ready to step up your photography game with simultaneous dual camera control? Grab this stereo shutter button and start capturing every moment from two angles!
