I'm not really looking for something light, more like something lightER than what I have. I don't need something I can stuff in my pocket and take snapshots with, I already have another camera for that purpose... I would rather go full SLR, or nothing.
From what I've researched, the 10D is one of the heavier SLR bodies made due to the magnesium body construction.... the body with battery alone weighs 870g, compare with the Nikon D3000 body with battery which weighs in at 536g. So that's about 3/4 lb in weight difference between these two. That may not sound like much but it's roughly the equivalent of carrying a 12oz can of pop attached to your camera strap.... after a while the extra weight gets annoying. The lenses are comparable in size and weight but my lens is not wide-angled enough for my landscape photography so I use a converter which adds another 120g and 2.5" of protrusion. Yes I could buy another lens that would serve my purpose but I would then have to sell the one I have to cover the cost... etc.
As far as what I'm using it for, probably quite a wide variety of situations, but mostly outdoor photography that involves not just walking but climbing up and down steep and somewhat treacherous rocky areas, staircases, etc. Places where it's hard to haul heavy gear.
But yes point taken, a better travel case would be a good investment as well for my purposes so I think I'm going to look around for one.
