Most of Canon's lenses have full-time manual focusing that allows you to manually focus even if the lens is switched to autofocus. But for lenses that don't have this feature you are required to switch to manual focus or you can damage the focus motor. Most of them are EF-S lenses. Which one are they?

(UPDATE 06/05/2012: THE WIFI BACPAC IS FINALLY HERE!)
For the fourth time it has happened again. Although unclear if there is another delay, the GoPro wifi-bacpac page has changed and this time there is more uncertainty to the exact release date for the Wifi-bacpac. First it was April, 2012, and now it's more ambiguous... Spring, 2012.
During the month of August 2011, my brother and I decided to film Guam's underwater treasures with a gopro camera.
The problem with using a gopro camera underwater is that footage will be blurred due to the curvature of the housing lens.
However, as of 2012, the GoPro company fixed this with the Hero 3 that now uses a fixed flat lens for optimal sharpness anywhere on the planet!
With a little modification by placing a flat lens filter, I present to you the first of hopefully many videos of Guam Diving... (for my detailed review of the GoPro check my GoPro article!)
