10 out of 10 points and recommendedSharp contrasty lens with very accurate AF and solid build. New rubberlike coating on barrel of lens.MF ring isn't dampened very well.
What a great lens...From the moment I mounted it on my 7D until now (about a week later) I've been blown away...first, by the build...It's solid and has a new rubberlike coating that just feels really good.reviewed November 8th, 2010 (purchased for $899)
Next was the AF....I was really amazed at how fast the AF was (after owning multiple 85L's). It's twice as fast as the mkII and maybe more importantly....Just as accurate.
The image quality is a bit of a mix between near as good as the L.... to... better than the L. It seems about as sharp as the L while the CA and fringing is much better controlled than the L. The bokeh is Signature Sigma 9 blade smoothness, like the EX50/1.4..It's very similar to the L. Very nice...Also....handles flare like a champ using the suplied hood.
All in all, a really nice lens
