to those of you who sent your camera in and had the issue fixed I envy you
17-55 sent in as it had some random focus issues and was really soft at 17mm. at first it was just about dead on with focus at 0 for MA but would just randomly miss at times. came back now needs +7 MA. granted sharper at 17 so far it seems and they did clean the dust from under the lens but the lens went in with more dust on the lens/body then how it started.
70-200 sent in. front focus at 200 back focus at 70. came back. front focus at 200 back focus at 70mm. same thing came back covered in dust.
7d went in for a err 80. and to see if lens/camera caused the issues. no more error 80 but had dust spots all over sensor and when it went in the thing was clean.
so all in all still not right and going to have to resend it in though just need some more time
hopefully this time irvine can fix it up nice though. and sorry just putting in my own story with canon repair.
