Ken Rockwell says, “The Nikon AF 135mm f/2 DC is Nikon's, and arguably the world's, greatest portrait lens. It has a very similar smaller brother, the 105mm f/2 DC.
The 135mm DC is also Nikon's sharpest 135mm lens, and an extraordinarily great lens for nature and landscape photography. It is worlds sharper and freer from spherical aberration than any of the the old manual focus 135mm f/2 lenses.”
I have read where people claim that this is the finest lens one will ever own. I'll bet that is a little bit of hyperbole. If price is an indicator that may be correct. Time will tell. I need at least a few days playing with a lens before I can properly judge it.
