How can i edit a .mov file? my Adobe Premiere Pro CS4 says it doesn't support the file. 

Does Canon covers grey market lenses (lenses that comes in white boxes) for repairs? why are they cheaper  (way cheaper) than the one that comes in original box? How do you read the date code on Canon lenses? your expertise is greatly appreciated.  

just purchased a 70D. one of the features that i like about this model is the auto focus on video mode. i was wondering, if i buy a manual only lens woudn't that make the AF feature on the camera useless? i bought the camera mainly for video.  Thanks...
