It will arrive with the new Rebel T4i. This has shown up in a US retailer inventory system. No price for the kit with the T4i." Why would you want a silent AF motor "geared to video" unless AF is working while you are shooting? Contrast detection AF can be engaged at any time by pressing AF button.

But you can't edit out the part where you're trying to refocus on Canon5DIII + Some L + Some non L + Some Sigma + Some Tamron + other stuff....

Gotta agree with you on that. Seems logical if kitting it with a lens designed for silent focusing with video. My junk

Yep, I know that this a Canon forum, but I am glad Canon has decided to add continuous AF A great photo only starts with the shutter release,
