Some cameras can be mounted without any software on FreeBSD. Yours is
not one of those so be it.
No we are going to use gPhoto2.
If you play (ON THE MENU OF CAMERA) with the options on YOUR CAMERA in
particular options for USB connector you will see that the following
options likely will be displayed
By default the camera is in Auto mode which is good enough for Windozzz
but FreeBSD might want you
to put camera in PTP mode usually used when camera is directly
connected to PRINTER via
Then just follow the steps I gave you.
I am 99% sure that your camera DOES work with FreeBSD.
