I've received my lens and camera back. As CPS said, they calibrate autofocus for my couple camera + lens. I've test lens again using Focal software. Result is more stable but not ideal. For my feelings in real (life) using result is same as before calibration. If I focus from infinity is more accurate than if I focus from close distance. If I focused from close distance and pushed autofocus button again after that, lens do a little more work. it doesn't happen when focusing from infinity.
My opinion: CPS - this is not a guarantee of good service.Although I sent to main CPS of Russia, which controle directly by Canon. I spent about 300$ for DHL delivery there and bac. For me result is nothing...
