The only down side I can think of is having to get SD cards instead of CF.
That and the D70 has a higher flash sync speed (1/500 v 1/250) other than that the D90 beats it in every respect.
Oh, I could think of a few things. Large viewfinder, excellent auto-focus and ridiculously good high-ISO springs to mind.I keep looking at a D700 no idea why though.![]()
