This camera works great with kdenlive and Kubuntu. Just connect it to the computer with USB and copy the MTS files to your harddrive. Then import them into kdenlive. Remember to proxy the clips in kdenlive, otherwise the video editing will be a bit slow! I've been using the cam for about 2 years.
Some advantages for this camera is the wide angle lens that allows you to capture more of the scene and quite good low light capturing. I also like that the cam is small and easy to carry in a (larger) jacket pocket.
Cons are only stereo sound (no 5.1 sound), and (as always with cams) the still shots are crap.
Some tests of the camera: http://www.otest.co.uk/p/sony-tests/hdr-cx305e-reviews.html
Superior performance and superb image quality are assured with the Handycam® HDR-CX305 camcorder. Light and compact enough to take anywhere it offers Full HD (high definition) imaging, the latest optical technology plus a range of smart features exclusive to Sony, all designed to make capturing your precious memories in brilliant quality, easy and intuitive. Group shots and landscapes look just as you intended thanks to a wide angle lens and 12x optical zoom. There's plenty of internal storage too so you can shoot up to 6.5 hours of Full HD video on its 16GB of internal flash memory. Want to take still photos? A 7MP still camera gives great results without the need for a separate stills camera. Plus shooting in low light is made easier by the acclaimed Exmor R™ sensor.
