Well I just received my MKIII back today after sending it in over a month ago. It made the trip to VA and then to NJ for some power problem they said. (Which it did not have prior to sending it in) Now I got it back, took it out tonight for a test drive. I now have the following problems and issues.
1) It will not format the CF cards. It will format the SD card but not the CF. I tried several cards and turned the power off and back on several times. And still the same error. I Removed the battery and re installed. Cleared all the custom settings. Etc. Nothing. I checked the same cards in my MKIIn and not problem.
2) It also will not boot up fast. It takes a few seconds after turning on the power before I can do anything.
3) After turning on the camera, I can not activate the menu for several seconds.
4) The focus seems slow and not very responsive.
5) None of my custom functions were changed when I got the camera back
6) My return slip said nothing about a sub mirror fix only an AF adjustment and returned back to factory standards.
7) I do have a white dot on the inside of the battery compartment.
8 Prior to sending it in, I had sent it in two other times to get the focus issue looked at only to be told that is was returned to factory settings and cleaned.
9) I had already updated the firmware to ver 1.3 prior to sending it in and on the return paper work it said that they loaded the most recent version but it was already installed prior to sending it in.
10) I have a big shoot this weekend and needed this camera but now I will not use it because it is still CRAP
. Even worse then when I sent it in.
I am so sick of Canon and the run around that this camera has given me that I am about to spend more money then the camera is worth just to hire an attorney and file a lawsuit. This camera has cost me lots of lost time, jobs and a big headache. Never again will I purchase a new untested product from Canon. And yes I tried to return it to my dealer two weeks after I purchased it only to be told that it was a Canon problem not theirs.
