A shameful thread, again. OP, please read the volumnous post by those who 'swear' and also swear that the problems they are having are with the camera. You question should more appropriately be: How many users need to be sent back to the factory to learn how to use the 7D?
Why is this a shameful thread?
There are dozens of members that have had defective units--problems that just went away after they were replaced.--or repaired.
Posters also "swore" it was user error--but in the end they were proven wrong.
Please reference the tango thread https://photography-on-the.net …read.php?t=847486&page=31 as an example--2 bad ones and an intervention by CPS to get acceptable results
