Ooo, Hi folks, I have never posted here before, so forgive me butting in.
I was once a national newspaper photographer, and I never really enjoyed 'photography for fun'. As a consequence the whole digital camera thing just passed me by. That is until I saw some landscape stuff in local galleries, I thought I could do better than that. I bought a D60 which was fairly light by DSLR standards and I started to take digital pictures (which I still dont fully understand). As others have said, the most weighty thing is really the glass that you screw to the front of the camera. I then found, after a couple of years, that my DSLR was being left at home more and more; I was either going on a photographic trip or I was hiking - but not both. I ditched the DSLR for a a Canon G10, as it gives you and excellent level of control over your settings. I have used this for about a year now. I have to say the results are not what I would expect for landscape photography: great for snaps and reportage style but not landscape.
The end result:
I carry the compact for day trips and quickie images, Nikon D80 and WA lenses for landscapes - I am happy with that.
