Thanks. I guess I'm looking for a "medium-format" appearance to my photos - spot on sharp but a nice "soft" texture as well.( my gallery may tell you more - "kneedoc"

I think I have done quite a bit with my various options with the D90 in terms of focus/metering/white balance performance. My 50mm, 1.4 lens is probably my sharpest lens but it's a $500 lens - not a $2000.00 lens.

I have a perception that a full frame camera will give me a "spot-on" sharper picture - (if I am willing to upgrade the lenses of course.)Am I wrong about that?

What would be the sharpest lens for a D90?

Thanks,
