I have a very old D70 and It still takes good pictures!
Your first pick: Nikon AF-S DX VR 18-200 mm F3.5-5.6G IF-ED Zoom / you think this coud be good allround lens - is good!
or a 35-70 and a 70-300 for Zoom! Nikon have a very in-expensive 35-70 like the type above, but their Zooms are expensive,
not unless money is no object! On a budget? Sigma and Tamron makes good Zoom lenses! You could also look for some used
or refurbished lenses online! Unless you're going Pro, (which I don't think you do or else you'll have a D300 and above), a
35-70 and a 70-300 should be good enough!
Definitely get an external Speedlight! You need it for wide angle and Zoom shots! The built in Flash does not have enough
power!
