Urgh, so looking the gphoto2 code the Canon cameras support manual focus in a totally different way. Nikon cameras let you nudge the focus point in arbitrary steps / granularity. Canon seems to be limited to just 7 separate manual focus points which really sucks. So I'll have to write some more code to deal with canon for this. > > And if I set the 'a' (autofocus), it "works" sometimes the first time > (= I see indeed a focus change relatively to the middle cursor), but > then nothing.

Can you try to test in gphoto2 shell eg just set the autofocus config parameter # gphoto --shell > set-config-value /main/actions/autofocusdrive=1 .... > set-config-value /main/actions/autofocusdrive=1 .... > set-config-value /main/actions/autofocusdrive=1 and see if the camera hangs in the same way. Also be interested if you can try manual focusing too - each of the 7 options > set-config-value /main/actions/manualfocusdrive=0 (near focus) > set-config-value /main/actions/manualfocusdrive=7 (far focus) > set-config-value /main/actions/manualfocusdrive=3 (middle focus) > set-config-value /main/actions/manualfocusdrive=1 (near focus) > set-config-value /main/actions/manualfocusdrive=6 (far focus) > set-config-value /main/actions/manualfocusdrive=2 (near focus) > set-config-value /main/actions/manualfocusdrive=5 (far focus) I really need to try harder to find a cheap EOS camera on ebay for testing :-) Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ Entangle-devel mailing list Entangle-devel@gna.org https://mail.gna.org/listinfo/entangle-devel
