just looked at the XSi specs.....nice. liveview is going to kill the entry level nikon cameras. everyone is going to want the liveview, especially with a 3" screen.
the lens is also an upgrade! the 18-55mm is an IS lens....cool! i see they also switched from CF to SD cards....not sure what to think about that.
the price is a bit steep for an upgrade from the XTi replacement at $900 w/lens. i wouldn't go as far as saying its a 40D-lite as far as technology.....its still vastly inferior....but its definiltely 40D-lite as far as the price goes. $500 difference.....i'd save and get the 40D.
but you can bet by thanksgiving/xmas 2008 that the XSi will come down about $200 for the holidays, making it an awesome buy.
thats what happened with the XT and XTi if i remember correctly.
Xsi looks nice too, but wow the price difference is too significant. I'm getting a feeling that many of you are Canon fans?
depends on what you are going to use it for. if you are going to use it 75% or more for aquarium stuff, then i wouldn't get a dSLR at all. i would instead get a really high end point and shoot for like $300-$400 that has built in macro capability, plus they make macro lenses for those also for under $100.
if you buy a $600 dSLR, you still wont be able to macro stuff. you have to buy that lens separately for around another $300-$400 min.
