Hi,
The message reads different, but its probably not obvious.

Basically, "gvfs" , the GNOME virtual filesystem has already grabbed
your camera to offer it in Nautilus as filesystem.
You will need to stop / kill the gvfs gphoto monitor process.
ps auxw|grep gphoto.*gvfs
to find them.
However, in this mode it will likely only allow downloading images.
Can you switch the A37 internally to "PC Control Mode" and try again?
This is needed for capture on the SLT series.
Ciao, Marcus
