Hi, I'm newbie to DSLR looking for something with some reach n work reasonably under low lighting (dusk, deep shade, dawn) without breaking the bank. Looking at 350D, or Olympus E500 or E330 type budget plus perhaps 3rd party longer lens of 300mm. Is this doable in terms of capability, etc? Is it worthwhile to grit teeth and go for D80 or D200 then add on from there? Right now using Panasonic Lumix FZ10. Do pl advise
