I have a problem with my new 5D3 and I was hoping someone might have some info or solution.
I bought it new 3 weeks ago. After shooting about 100 shots to test it out over a day, the 5D3 worked fine.I then sent it to the Canon Service Center (Irvine,CA) via the Honolulu office for calibration with my 70-200Lii.
I got it back 2 weeks later and the 1st time I used it (2 days ago and every time since), I can't download the files to my MacBook Pro (v 10.6.) using the camera to USB cord. EOS Utility opens, recognizes the camera and when I click on download, it seems to initially try to start the download but then after 1 minute (with no downloads), it crashes and closes. I tried using the latest ImageBrowserEX, which can see all the images on the CF card in the camera, but then it also can't download from my 5D3 and also closes without any images downloaded.
I've downloaded the shots without any problems by putting the Sandisk CF card into my 7D or using my card reader. I've updated the EOS Utility to the latest version and tried several CF cards and different USB cords with the same results. I called Canon Tech support, but they had not heard of this problem and couldn't help me.
The 5D3 firmware version on the camera when I got it back from Irvine is 1.1.3. I think I saw it was the newest firmware version 1.2.1 before I sent it to Canon. Bummer! Has anyone heard of this problem. I'm taking it into the Honolulu center tomorrow to see if they can help, but they have very limited capability. They said they will update to the newer firmware (which Irvine should have done) to see if that fixes it. It may have to go back to Irvine for a fix. I have 45 days to return it where I purchased it here at a camera store if they can't solve this.
Thanks for any help or advice. I think I will love this camera if it would work correctly.
