The exposure latitude of negative film is still wider than
general digital DSLR shoot, ie. even in a "properly" exposed picture u may easily see hotspot highlight and/or under-exposed shadows, etc, in a DSLR shot. One the other hand, if u over-expose negative film by +1.5 stop u can still find decent picture quality, but if u over-expose D100 by +1.5 the picture highlights are all washed out. (Sorry I seldom take trans)
In my opinion, as for my D100, it's colortone on artificial light still has a lot to catch up to match film.
Having said the above, I must say if u can afford super-expensive DSLR like Nikon D2's or EOS 1D... I
THINK the DSLR quality will match (if no better than) film.
