Enhance your smartphone photography with the Pictar Plus Camera Grip for Android phones, iPhone 6 Plus/6 Plus 7/7 Plus 8/8 Plus and iPhone X from Miggo. This ergonomic grip features wheels and buttons that, when paired with the accompanying app, give you greater control over your photography and let you use your smartphone camera one handed, even with gloves. It works by emitting high-frequency sounds that are detected by the free Pictar app via the microphone, saving battery over other wireless methods of communication. Using a standard CR ? AA battery (included), we estimate 4-6 months of use before the need to replace the battery. The Pictar Plus is coated with anti-slip material and comes with a wrist strap and a padded neoprene pouch. Shutter: The Pictar?s shutter, positioned for easy index finger access, can be used with gloves and has a ?half-press? function, enabling you to lock focus and exposure while tracking a moving object. Zoom:A rotating zoom ring is located underneath the shutter button for one-handed access. If desired, the zoom ring can be reprogrammed to control other functions, such as flash or white balance. Exposure/ISO: The top right corner features an exposure compensation wheel, that lets you change exposure in 1/3 aperture steps. In fully manual mode, the exposure wheel changes ISO instead. Smart Wheel: In default mode, the smart wheel lets you select between seven preset modes: auto, portrait, landscape, sport, snow, selfie, and video. In advanced mode, it will switch between shutter priority, ISO priority, and fully manual. Selfie Button: By clicking the zoom ring, you can switch between front and rear cameras for self portraits. Like the zoom ring, the button is also re-programmable. Virtual Wheel: The app?s virtual wheel lets you control flash modes, shutter speed, ISO, and more. Tripod Mount: A 1/4?-20 tripod threaded hole lets you attach the Pictar to standard tripods and monopods. Cold Shoe: A cold shoe supporting up to 10.6 oz enables attachment of accessory lighting or microphones. Lens Ready.
