IMHO, its virtually impossible for this one to justify its cost unless its a seriously outstanding lens.
As for the comment on focus speed, thats nonsense. Some of Canons fastest and most accurately focusing lenses are the big guns. This one should zip along like the 35/1.4 at the very least.
I think you are right there. An outstanding lens to me also means "outstanding thruout its operating aperture values, starting with the nominal aperture". A lens which is "outstanding" only when stopped down 2 stops, needs (ideally) to be re-rated and its price should drop (ideally) like a stone.
The key to a relatively huge popularity the 85L has enjoyed over almost past two decades, despite issues like CA, is that the lens is quite well performing at its nominal aperture.
However, as far as AF speed is concerned, I am often at a loss regarding people's expectations .......even if the lens AF drive speed turns out to be just comparable to the old EF 50 f/1.4.......how would that diminish the utility and value of the new lens ?
