Canon 18-55mm lens torn open to expose visuals of Image Stabilization (video)
Hey there, snap-shooter. If you've ever used a Canon DSLR with an 18-55mm lens, you may be horrified to know that the image above is its exposed lens elements. Don't worry, though, it's for science! Recently, Preston Scott from Camera Technica used a laser to show how unsteady your hands are when taking a photograph; now he's back to detail how lenses with Image Stabilization compensate to help in achieving crisper images. IS isn't exactly new technology, but seeing how the glass' internal springs, accelerometers, and gyroscopes react to movement is mesmerizing. Not surprisingly, he also found that photos taken with IS deactivated were usually less sharp. You'll find a steady video of the action past the break, as well a detailed breakdown by hitting the source link below.
Lasers prove you can't hold a camera still (video)
If you think schlepping a tripod along with your DSLR isn't worth it because you're convinced you can get a clean shot if you just concentrate hard enough, we have to ask... how's that working out for ya? To demonstrate the destructive power of shaky hands, Camera Technica attached a laser to the hotshoe of a Canon 7D, with the light reflecting off a wall 20 feet away. The lesson: it's challenging enough to get a crisp shot with a tripod -- let alone without. In the video below, the laser point wobbles erratically when the photographer gingerly presses the shutter with his finger. In the second clip he uses a remote release, which visibly cuts, but doesn't eliminate, the shake. Only when he locks up the mirror and resorts to a remote release does the shaking drop to a minimum. Need some more vivid evidence? We highly suggest heading past the break for a demo that might just make you reconsider that decision not to pack a Gorillapod.
