What would you consider as "general servicing"? Will they do calibration on the camera that may cause backfocusing or they will just clean the sensor, test the shutter, etc). I don't think my camera is back focus now (at least with the lenses that I have) and I am a bit worry that it will if they do some sort of calibration work when they service the camera. Last but not least, any clue on how much will that cost?
Very interesting point. I had a slight problem with the 10D and 24-70L combo lately. Seems like a bit of back focussing esp with subjects that are not contrasty.
Then use my wife's 350D - picture sharp again. Could it be the 10D is beginning to have some problems?
