You know the game.... what's in it?
Bokeh is nice . But my only concern from my preliminary results is that it seems really soft at f/1.7 and does get better as I close in on the f3.5-f4 range but even then my Tamron 17-50/2.8 is much sharper at the same 50mm. I guess it's just for some good bokeh, smaller images (not 100%, as these are), and low light indoor situations?
Some of my initial observations of the lens is that WOW, it's really small, especially on the camera, takes some-what decent pictures, blows the kit lens away obviously, and that it is very fast (the AF).
