Summary: Nice lens, focus is quiet and quick, much better than screw drive. Not the sharpest wide open but most zooms are not. Just stop the lens down a bit. On Pentax cameras this is no need for the optical stabilization so just leave it off. Sigma has removed this on their newer Pentax lens. Build is typical Sigma, light with little metal, but that is what makes it light. Good lens for everyday use but there are newer lens out that are better.
Summary: I really like the lens...does great for my need...can't beat it for the price...I have taken a lottttttt of photos with the lens...BUT what I have taken I've been rather impressed...again considering the price I paid for the lens...so yes...I'm enjoying the lens and would recommend others who may be on a slight budget like myself to try this lens out. I don't think you'd be disappointed.
Summary: I'm not a pro by any means, but I am happy with the money I spent on this lens. I'm getting some great shots. I'm sure that some more seasoned users will find fault with the glass quality, etc.
Summary: In my first foray into photography, I decided to take a telephoto lens instead of the kit lens (bought a Nikon D5100 separately), to shoot pictures of people and food (what can I say, I'm -sortof- from the Instagram generation). I am not qualified to comment on the quality as compared to other lenses (I am neither a professional nor do I own other lenses). All I know is I'm satisfied that this lens is telephoto, and it works as advertised.
