Summary: I have another sigma lens 70-300 before buying this one so I was impressed with that one, but I wish I can say the same for this. I'm using it on my sony a37. Lens' autofocus gets lost a LOT and when it does get lost it has a very hard time coming back from it. Sometimes, it just stops autofocusing because it's so lost (very annoying). I planned on using this lens for some wedding photography but that's changed now because of the slow af...
Summary: Pictures were sharp and bokeh was decent but my shots lacked contrast and saturation. They just looked a little washed out. At first, I thought I just had exposure setting issues or that my D90 photos simply had a different look to it. I changed my D40 to a D90 about the same time so this wasn't a controlled experiment at the beginning. Later I got some Sigma EX lenses as well as the new 18-250 OS lens that isn't EX and my pics suddenly jumped to life.
Summary: I just wanted to point out that the f2.8 is not constant on this lens. You can only shoot at f2.8 at 70mm, as soon as you pull back , that aperature will change. If you want a constant f2.8 over the full range this is not the lens for you.
Summary: I couldn't afford the Nikon 24-70 lens, and I was not too sure if I could remain constrained with the fixed focal length 85mm lenses. I needed something definitely wider than 24mm. This lens met all these constraints Bought it after much wrestling with choices in my budgetary zone, and my first thoughts: I think it's a fine lens. I have shot some portraits, landscape and snapshots, I must admit the lens is sharp enough and color rendering has been vivid and faithful.
It seems that fast and cheap wide zoom is still a pipe dream

Summary: I was excited about this lens when I saw all these reviews that seemed to suggest that it was the holy grail of walkaround lenses: fast, has a super-broad zoom range and is under $500. But when I got it, I was immediately underwhelmed. It is very soft at 17mm and at 70mm, with the only good focus away from the extremes.
Too many bad copies of this lens being produced...

Summary: I got a bad copy. I read a ton of reviews online about this lens and knew that it was a crap shoot as to whether you'll get a good copy or a bad one, but the more you look it appears that there are quite a few bad examples being produced; so many, in fact, that it makes buying this lens a real gamble. For such spotty production the 1 year warranty from Sigma is simply too short and makes this lens a risk.
Excerpt: This is a fantastic walk-about and general purpose lens for cropped sensor Digital SLRs -certainly for value for money, it's unbeatable. It does not feel cheap, the build quality is good, it feels sturdy and it comes with a zoom lock, which prevents the zoom sliding out when walking about. The body is susceptable to scratches and marks due to it's matte finish, but it's not really a big issue.
Pros: Superb value for money, great image quality, good construction, high maximum aperture
Summary: Ich hatte dieses Objektiv für meine Canon 40D bestellt und war etwas enttäuscht von der mittelmäßigen Schärfe! Ich habe mir dann das Tamron 17-50/2.8 bestellt, welches zwar nach oben nur 50mm hat, aber rattenscharf ist und mlt Blende 2.8 auch lichtstärker!
Summary: Das Sigma 17-70 erschien mir doch sehr interessant, da das Kit Objektiv eindeutig etwas zu wenig im Telebereich zu bieten hat und auch etwas Lichtschwach ist. Also mal sehen, was es bei der Konkurenz gibt, da die Pentax Linse doch etwas meine finanziellen Möglichkeiten sprengt. Ausgepackt machte das Sigma eine gute Figur. Viel besser als die Sigma Linse die ich vor ein paar Jahren für meine Nikon kaufte.
Summary: Ich habe das Objektiv als lichtstarkes "immerdrauf" gekauft und bin im großen und ganzen zufrieden damit. Allerdings ist es für die D40 nur eingeschränkt gut, da durch das Objektiv das AF-Hilfslicht teilweise verdeckt wird, was natürlich bei nicht so guten Lichtverhältnissen ein Nachteil ist. Ausserdem sieht man bei Benutzung des integrierten Blitzes und einer Brennweite von 17mm immer einen Schatten des Objektivs im unteren Bildrand.
