Part awesome party-trick, part brilliant idea, the new Cycloramic app from Egos Ventures is about the coolest thing you can get for one dollar on the iTunes app store at the moment. The app — which will only work with the iPhone 5 — triggers your phone’s vibration at the exact right frequency to make it spin around in a perfect circle. Just stand your phone up, hit go, and keep an eye on your friend’s faces (several reviewers called the reactions “priceless”).
How much does a camera vibrate due to your finger pressing the shutter or the mirror flipping? Camera Technica decided to conduct a test by strapping a laser pointer to the hot shoe of a Canon 7D. They then filmed the red dot on a far wall against some text while shooting normally (i.e. pressing the shutter with a finger), using a remote shutter release, and finally with a remote shutter as well as mirror-lockup.
You might be surprised at how much movement the camera experiences even if the shutter is pressed carefully. Lesson learned: for the sharpest possible photos, use a tripod, a remote shutter release, and the mirror-lockup feature on your camera.
