10 out of 10 points and recommendedAffordable, sharp at F4 - 8, OS worked, closeup/macro is a bonus @ 20cm, non rotating zoomSoft @2.8, nothing else ATM until I run a field test
I just got the lens and took some picture with hot shoe flash at night, this is what I think about the new Sigma 18-50 F2.8-4.5 OS HSMreviewed March 15th, 2010 (purchased for $270)
1) Build - Can't be compared with Tokina but acceptable
2) Zoom ring - damped well controlled
3) IQ - pretty sharp even at f4. Very sharp at f8
4) Bonus - closest distance approx 20cm, can be use for closeup/macro which was NOT advertise as a feature. When I add 2x teleconverter, this will give me macro effect.
Will post image in flickr sometime this week. Overall I'm very satisfied especially $$/quality features.

A perfect lens for landscape and street photography for A7. Lightweight and small yet produced a magnificent images. Like everyone who already reviewed this lens, I agree that it can produce sharp image even at wide open. Colour rendition is also very nice. Bokeh is average but smooth especially when taken at the minimum distance.reviewed April 17th, 2015 (purchased for $580)
I have not done extensive test but this lens is indeed a keeper and most likely will stay on my A7 most of the time.
Construction is similar to the E mount lens especially the E 50mm F1.8. Not the highest quality but very good.
Once concern is the glass element is quite exposed and I can only feel I need a UV filter to protect it.
Zoom is generally very fast. Even in low light underexpose condition, I managed to get tack sharp image with external flash (ring flash diffuser).
For the $$, this is the best value for money lens with high quality image.

Fast AF especially when combined with A6000. Sharp even at 200mm. This is the Canon L F4 equivalent but also has a very creamy bokeh.reviewed April 17th, 2015 (purchased for $850)
It worked well for portrait and sports. Also a keeper for A7/A6000 Sony cameras. Only wish it could be smaller.
8 out of 10 points and recommendedLight, OS, good kit lens with good focal rangeNot tack sharp, what bokeh?
Simply a very good kit lens. Can't complain. Does get good image but I would not consider it tack sharp but not soft.reviewed April 17th, 2015 (purchased for $250)
I keep this rather than spending on Zeiss 24-70 F4 for travelling.
