When you buy a new peripheral, you always find the drivers for PC, for MAC (the situation is going better).
Yes but for Linux which is a free operating system, the builders don't supply specific pilots.

Please, feel reassured, you just have to get (what is very big term, because the application is free and is easily either on Web, or with distributions Mandrake or RedHat) the software gphoto (you'll find it on rpmfind.net).

This one get the drivers of every still digital camera and is regularly updated..
