We shared a video of Canon’s Image Stabilization technology in action in the beginning of the year, but that was on a pro telephoto lens and inside a glass display case. What would the same technology look like in a cheaper, consumer lens? Preston over at Camera Technica decided to find out, disassembling a Canon 18-55mm kit lens to capture this short video of the IS mechanism in action. I had no idea the thing used springs, did you?

Here’s an interesting look at what the aperture blades on a Canon 18-55mm (the kit lens for many DSLRs) look like. The video above shows the blades moving into position at 120fps. This happens every time you shoot a photograph and in the blink of an eye.
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.
