I recently purchased a used Canon 24-70 f/2.8L II lens and was thinking of sending this lens into Canon for their 11-point EF lens maintenance service just to get everything cleaned and checked out. This also got me thinking whether or not I should consider sending in my 7D2 for either the 7-point or 18-point maintenance service. I am not having any issues with either, but just wondering how beneficial it would be.
I was curious if anyone here has ever sent their 7D2 or any other camera or EF lens into Canon for maintenance and what their experiences were. Curious to hear good, bad, and whether or not you felt it was worth it. I don't know what the typical turnaround time is to receive the camera or lens back, but figured the winter months would be a good time to do so. Any input is appreciated!
