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 of the the break, as well a detailed breakdown by hitting the source link below.
