Hello,
I use a 1200D for capture with a Raspberry Pi , manual focus switched on the lens, both with USB (for downloading pictures) and with remote cable release (cable+optocouplers for triggering the camera) , timelapse every 20 minutes, no pictures in the night . Gphoto2 version is 2.5.10. Sometimes, the 1200D is blocking , no way to capture a picture , no reaction from the camera. This happens every morning and most of the time, the camera unblock after one or two hours . But sometimes , It happens also in the day (but only one or two pictures lost). This problem happens with a 1200D but with a 1100D , it was ok. When the triggering by cable fail , trying to capture a picture with --capture-image-and-download also fail. The only way that I have found to unblock the camera is to switch power off manually and switch it back on manually. I tried to use autofocusdrive=0 and cancelautofocus=1 , thinking the autofocus could be the problem. I have tried this : sudo gphoto2 --set-config autofocusdrive=0 --set-config cancelautofocus=1 But when I verify cancelautofocus : sudo gphoto2 --get-config cancelautofocus Result is : Label: Cancel Canon DSLR Autofocus Type: TOGGLE Current: 0 So I guess I don't use the good commands, or I don't made the good things ... How to set cancelautofocus ? I don't know if my problem really comes from manual focus , could it be another thing ? Your help would be welcome because I work on this problem since more than a week without finding any solution. Roberto. |

No, likely not. If you are using 2.5.10, please upgrade libgphoto2 to 2.5.12 as it contains fixes for the EOS 1200D and see if that works better.
