Comment 29 for bug 351122

"Why would you mount a PTP camera at all?"

why should a user care about the difference between a PTP and Mass Storage camera? they just want to plug in their camera and retrieve their photos.

The advantage of mounting is that multiple apps can share access to the device. I don't know why the devs of the leading apps are taking so long to upgrade their scripts. Getting the apps to work with gvfs-gphoto is not hard and as far as I can tell there is little to no performance impact.

"Surely the backend should distinguish between cameras with
usb mass storage access and those with ptp access"

It actually takes more work to mount the ptp camera, but it is work that gvfs-gphoto takes care of. This should be making it easier for would be application writers. (I know, I'm one of them: https://launchpad.net/phraymd)
