My budget is around $700 (with kit lense) with 10M pixel. So I narrow it down to 4 models: Canon 400D Rebel XTI Olympus E-510 Nikon D40x Sony A100 They all have great reviews from dpreview.com. Which one would you choose? I am leaning towards Nikon D40x. The next step up is Nikon D80 which is around $250 more than D40x. Worth it? What other choices in that price range? I am willing to pony up extra $$. Is there DSLR that allows you to compose the picture thru the LCD screen instead of the viewfinder. I am spoiled with the convenience that point & shoot camera affords me to do just that. How about lense? Suppose I pick the Nikon, which is the better all-purpose lense 18-55mm f/3.5-5.6G or 18-135mm f/3.5-5.6G ? How much heavier and longer is the 18-135mm? Nikon uses lossy compression for RAW files instead of lossless compression or uncompressed. Does it matter to you?
