I happened to check out a D-40 today at Walmart. I am fairly used to the E-510's viewfinder but I figured MF on a DSLR just didn't happen. The Nikon must have AT LEAST a 1.5x larger viewfinder, if not twice as large (not correlating this with any crop factor, it just seemed roughly that much larger) and much brighter. I kid you people not when I say that the D-40's viewfinder almost seemed STRANGE to me. I feel so depraved now.
