Mount Ring Canon
| Powered by phpBay Pro |

What would be damaged, the camera or lens or both?
While fitting a lens hood on a Canon 18-55IS Lens (mounted on the 1000D/XS) I accidentally turned the focus ring (clockwise and counter clockwise, about a 1/4 turn at worst) WHILE the AF switch was engaged.
I have not repeated the error. When I did inadvertently turn it that 1/4 turn, I noticed that the resistance was fairly minor. It felt and sounded like turning a small motor shaft by hand. A friend said that in some lenses -- without an FTM features -- damage "could" result from turning the ring while in AF mode.
What gets damaged? The gearing in the lens, the motor? Could it damage the camera electronics itself (if camera on) by sending a small current backwards?
The camera still auto focuses but have I done any damage?
Any actual experience with this issue?
thanks?
I've made the same mistake myself. It will be fine. Think about a RC car...if the car is on and you turn the wheels backwards, then all it does is reverse the motor. I would have to suggest that everything will be OK, but I wouldn't do it purposely.
