Canon A60 - retracting the lens with capture=off is not working!

[Jiri Hladky-2]

Hi all,

I'm using gphoto2 to create lapse movies with Canon A60.

As already reported by Günter Neustädter
(http://sourceforge.net/mailarchive/forum.php?thread_name=916638.14125.qm%40web53011.mail.re2.yahoo.com&forum_name=gphoto-devel),
retracting the lens with capture=off is not working.

Actually, it's not working from command line. When I request
capture=off from cdk menu then it's working.

Can you please help me to resolve this?

Thanks a lot!
Jiri

Facts:
1)capture=on is working fine
2)get-config ALWAYS report that capture is in state off
3)capture=off is not working
gphoto2 --camera="Canon PowerShot A60 (PTP)" --debug --debug-logfile
/tmp/capture-off --port=usb: --set-config /main/settings/capture=off
See attached  debug-logfile /tmp/capture-off
4)when using cdk shell (--config), capture is always first at state No
(Off) (even if the real state is on). When I switch to Yes (On) and
after it to No (Off) then the lenses are retracted. So it seems that
capability is here but it's buggy and CANNOT BE ACCESSED FROM SCRIPT
USING --set-config /main/settings/capture=off

See attached log-file config
gphoto2 --camera="Canon PowerShot A60 (PTP)" --debug --debug-logfile
/tmp/config --port=usb:  --config


gphoto2 --version
