same, about one year... the problem is, that on the 50mm it's not so bad (about +4) but on 17mm it's almost not to use (about +11 and corrections depend on distance from the object), i'm thinking about same or buying 28/1.8 usm for 5d - almost as wide as 17mm on APS-C.

on 50d and newer you can make a correction of backfocus or frontfocus
