Re: why not a bridge camera?
"In fact - what exactly do you get in a DSLR that you don't get in an FZ28? Please don't flame me - I really want to know."
The hint is in the name - FZ28 - widest angle is 28mm. The K-m (and most DSLRs) come with a stock 18mm to 55mm lens. 12mm through to 20mm is great for landscapes. 28mm is great for - well, just general pics of stuff if you have room to step back a few paces, but with a landscape shot, you can't do that. I used to have a Canon S2-IS - it has the same issue - at widest it had a cramped feel - but it has a 12x zoom - great for shots of birds 20+ metres away, crud for landscapes.
I'd say that 80% of my shots with my DSLR with the stock lens are taken at 18-24mm range. It feels less cramped and gives a sense of space.
