Just got this lens and am pretty much addicted to it!

It is successfully replacing my 35mm f/2 in daily "let's go for a walk" usage, alongside a 90mm Tamron. I really can't stand to use a zoom if I don't have to.

My preliminary judgement is that this is a lens whose strengths are sharpness wide-open (no mean feat for such a bright lens) and an ease of use that it's well-implmented AF-S brings. I'm actually a little disappointed with the bokeh. It's certainly better than the 35mm f/2, but still falls apart a bit when there is too much to distract in the background. That said, the shallow depth of field can be used to give a nice effect if you are careful what you allow in the background. I like the rounded aparture blades, too, much better than the old bee-hive effect!

Another problem is the distortion. This lens, if you are at all interested in architectural photography, will just have to be digitally corrected. Yes, it isn't a'pro-grade' lens as such- But I am sure it is capable of some pro-grade results if carefully used.
