Summary: Not super sharp, I was a little disappointed. I find that the Sony lenses just work better with Sony cameras. After shooting a bunch with this lens I feel that I'm kind of done trying to make the low end Sigma lenses work with Sony cameras (I have the e mount model).
Summary: Good build quality, metal mount, mounts very tight to the camera body. Nice manual focus ring, nice lens cap and hood, and pouch. Takes ok pictures, I am not seeing much difference from my kit lens (Olympus 14-42mm iir). But f2.8 makes it take better low light pictures than the kit lens.
The best lens for the money isn't necessarily a nice one

Summary: We M4/3 adapters are marred with an extremely exclusive and expensive lens market. We're faced with fairly expensive lenses from Zuiko and Leica, but Sigma is offering us a boon in the guise of a Nifty-Fifty equivalent. Well, it's anything but.
Summary: After using this lens for a while in a variety of settings, I can say with some certainty that unless you absolutely need the larger f/2.8 aperture, there's no reason to choose this over the 14-42mm II R kit lens. It has more color fringing, softer edges, and work against bright light sucks.
Summary: I got this as an upgrade from 14-42 kit. the bokeh just isn't there. or should I say just not enough of an upgrade. if you had a body only, YES BUY THIS. but if you're looking for some sweet bokehliciousness, you should PROBABLY go with the panny 20mm 1.7 (I do not own which is why I'm enphasizing...
Summary: Okay, first of all this a pretty nice lens, construction is nice, and I can get quite good photos with it, however it does have some drawbacks. This lens is essentially a compromise, and its one that I've regretted. If you want a wide angle lens, this doesn't feel that wide, and its not very fast.
Summary: Aufgrund der vielen positiven Rezensionen und des günstigen Preises habe ich mir dieses Objektiv mal zusätzlich zum vorhandenen Kit - Objektiv für meine Nex7 gekauft. Schon beim Auspacken der Schreck; das Ding rappelt wie ein Sack Nüsse.
Summary: Das Objektiv ist sehr gut, aber es bringt wenig an einer Lumix (G3). Der Vorteil in der Lichtstärke gegenüber dem Kit-Zoom (14-42) geht wegen fehlender OIS verloren. Vergleich zum Kit-Zoom (bei 19mm): Es ist nur unmerklich schärfer (bei gutem Licht). Das Bokeh ist schöner.
Summary: Ach was tut es mir leid, dem Sigma hier nur drei Sterne zu geben!!!! Aber was soll man tun, wenn's halt nicht ganz passt. Aber der Reihe nach: Optisch ist das Sigma nahezu konkurrenzlos, in seiner Preisklasse sowieso generell.
