"Excellent Quality! Crystal Clear!"4.5 starson by ultravibe
Pros: Image Stabilization, Fast Focus
Cons: Low battery on the 10D causes an error at times
Summary: This lens is incredible! Many, many more keepers. Only thing I have noticed and not all of the time, when the Canon 10D battery is running low this lens may cause a communication error between the body and the lens forcing you to shut down the camer, slightly dismount the lens and remount and then it works. It's pretty rare but for the price you'd think it would be flawless.
