I have a Nikon Coolpix 4500, and found following through Google:

------
To have the rights to download files from a digital
camera, add following to the "/etc/devfs.rules":

[usb_devices=10]
add path 'ugen*' mode 0660 group operator
add path 'da*s*' mode 0660 group operator


..and restart "/etc/rc.d/devfs restart"

..add yourself to the "operator" group.
------
For me it just worked then. Sometimes it will fail during the initial
attempts to download files, but then I just switch off the camera, and
on again, then it works.

It might be better, security wise, to have a group called "camera", instead of
"operator", but have not tried it.
