I saw that... I'll be curious to see how it performs. There's no mention of the # of blades, which seems to be a big factor in how the bokeh looks on such lenses.
I was also glancing at the Zeiss 50mm F1.4 which is available in Nikon and Pentax mount... interesting but the MF might be difficult when it gets dark enough to really need such speed.
It'll certainly be a tough sell in the Pentax mount due to the low price of the OEM one but the more choices, the better! I could see it being a fairly big success in the Nikon field for those D40/D40x/D60 owners, like Kyle said.
Now, if Sigma would come out with a good, affordable 85mm F1.4, they may get some of my money... c'mon, Sigma!
