Do you feel as though your iPhone just doesn't, well, DO enough? With the ioShutter Shutter Release Cable With N3 Connector from ioShutter, you can use your underachieving device to control your DSLR camera--Timelapse, Bulb, Timer, Sound trigger and a ShakeToTake movement trigger.

Using this 2.95' (90 cm) release cable and the free app (which can be downloaded from the Apple App Store) on an iPhone4, iPhone 3GS, iPhone3, iPod Touch gen 4, iPad1, or iPad2, you have control over your DSLR. Timer, Bulb, Timelapse, Sound Trigger, and ShakeToTake functions are available and will operate together--use a Sound trigger for a Timer exposure, use Timer for a Bulb exposure, or ShakeToTake to trigger a Timelapse exposure. This release cable is also compatible with the Pro App available for sale separately in the App Store. The Pro App expands the functionality of the modes.

This cable is compatible with a variety of cameras. These cameras have been lab tested for compatibility:
Canon 5D Mark II, 5D, 7D, EOS-1D Mark IV, EOS-1Ds Mark III, EOS-1D Mark III, EOS-1D MARK II, EOS-1D MARK IIn, EOS-20D
