The Bluetooth Smart Trigger from Satechi slides onto the hot shoe of your Canon, Nikon, or Pentax DSLR camera and adds new dimensions to how you can use the camera. The Smart Trigger uses Bluetooth 4.0 technology to pair with your iPhone (4S or 5) or iPad (3 or mini); an iOS app then turns your device into a remote trigger release accessory. Bluetooth 4.0 has a range of 50 feet, and the low energy consumption means you can get up to 10 years from a single battery. You’ll be able remotely trigger the camera in three modes. With Regular mode, you can wirelessly trigger a shot – so you can make sure you’re always in the pictures, too. Manual mode locks open the shutter for long exposures to capture star trails or light-writing shots. Timed Shot mode turns your camera into an “intervalometer. Fine-tune your timer settings and use this mode to perform advanced photography techniques like time-lapses.” The Bluetooth Smart Trigger is available at an introductory price of $44.99 at Satechi and Amazon. The iOS app is free in Apple’s App Store.
