I had a problem with the camera ,I was silly , I tried to operate with the CHDK 110d
formated sd card whith eos card and the camera no longer wanted to restart.
I removed the battery for 12 hr and re-tried, I pressed all buttons but impossible to make it re-operate.
I was afraid and i'm going back to the store to exchange ,and the seller tried to operate the camera and it went back to work.
I think but I'm not sure that the camera went back to work when the lens was removed and replaced because I had not removed and replaced the lens .
I nevertheless exchanged it for for the sony camera again,canon is a good caméra but after having tested the 2 cameras I think that the sony camera gives a better image whith less picture noise than canon M10 . And also iI was afraid of damaging the camera again, But I was wrong this did not cause any damage to the camera and apparently it works with other people.
There may be still the problem of star eater with sony camera but I will do with.
Thank you for your work.
