You may need gvfs-gphoto2 for the file manager to see it.
Photo cameras are usually offering PTP (Picture Transfer Protocol) or its extension MTP (Media Transfer Protocol), not mass storage. The protocols, aside from giving access to photos, may allow controlling the camera remotely.
Thank you friends for your trying to help. But none of the suggestions worked. In fact I had already tried those before writing to the mailing list. Finally one of my friends (not in mailing list) suggested me to install 'shotwell' ( https://archlinux.org/packages/community/x86_64/shotwell/), and it solved the problem. After installing 'shotwell', when I made the camera 'on' after connecting to my PC's USB the camera got mounted and the icon came up on the Desktop. I reported it here as an information service. Thank you all. dd
