Your child is swinging, running, playing actively.
Now you can capture pure energy in pictures!
Kid won't slow down? Panning* technique is tricky, but worth trying.
Just set a Canon IS Lens to Mode 2 to correct vertical camera shake while taking pictures.
The result? Panning shots made easy - so you can catch that kid for keeps!
Chasing your child with the camera? It's hard to
even keep the kid in your viewfinder! And when
you take the shot, you push the shutter button
too hard - shaking the camera and creating
vertical blurring. But no more! Canon IS Lenses
with Mode 2 help you get the picture right.
