Before i used Canon 15-85 and pentax 16-45. İ think this lens better than Pentax 16-45 and canon 15-85. it's optical quality like a prime lens.it have perfect sharpness and contrast. Body quality is so good, but it's heavy. There is no featherlike coating ( i think new coating so nice). There is some back focus problem with my copy, but focus is very silent and fast. There is vignetting at 17mm. Colors a little yellowish. I mean classic sigma colors. At the end, i can say this lens is so good and It's perfect for landscape and portrait

The HSM is quiet. The optics of this lens is OK. I compared the bokeh of this lens with my Pentax DA* 50-135mm at f=2.8, the Pentax one's bokeh is significantly smoother than this Sigma. The biggest problem I had with this lens is the slow focus at 50mm when aperture is opened to 2.8. I have to shot a indoor wedding, the focus speed of this lens for sure cannot help me catch the most important moments for my clients. I return it in exchange for a FA 77mm limited.

    Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

    HSM are quiet and fast on my K-3 body; a great lens when compared to similar offerings elsewhere. Aperture of f2.8 was indeed quick, but not quick enough, but please don't blame Sigma! My tastes are begining to lean toward the prime lens. I had to think long and hard about keeping this gem. I ended up using B and H's gracious policy to return, so I can fund pricier primes. Based upon Sigma build quality and price? I will definitely consider their prime offerings; they seem to make nice stuff for Pentax, wish they made more!

      Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

      I've only had this lens a couple weeks and have only been able to take test shots of pets and family/friends. Thus far I'm extraordinarily pleased with its performance, especially considering the price. This was my upgrade from the standard 18-55mm pentax kit lens. The Sigma produces very sharp images with no chromatic aberration (until you blow-up the pictures to full size on a giant monitor and even then its very faint). I love having the large aperture through the entire zoom and surprisingly feel comfortable shooting wide open and can expect sharp images. Great for indoor lighting events. Macro performance was also surprisingly strong. The only thing this lens is missing is a weather-sealed construction.

        Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

        Over the weekend I really put this lens to the test on my Pentax K-3. I had to shoot a First Communion in a church not well lit, the second was a baby shower inside a room with very large windows on three sides of the room on a sunny day!! Lots of glare here.

        In both situations this lens worked brilliantly!

        First - the lens is so very responsive and QUIET!!
        Focus was smooth & quick. Of course what matters most is the end result. The photos were clear, crisp and amazing! And that made me very happy.

        This is my first non-Pentax lens. I am now a HUGE SIGMA fan!!! If you're on the fence about this lens, don't be. This SIGMA lens is all that it says it is and more!

        Had to get my camera & the lens in focus with each other, once that was done it has produced great pictures. It is very quiet & fast on the auto focus, but tends to re-focus before I shot.
        Other than that it is a great lens and produces nice pics.

          I love this lens. I bought this lens to photogragh my family during the Holidays. It is perfect. The photos are very shape and vibrant. I did not use a flash light. The light source was from the lights in the rooms. This f2.8 lens is perfect to photoghragh in low light.
          Sigma did a good job. It is an excellent lens.
          Thank you Sigma.

          I researched fast wide zoom options for a while. In reading the reviews on the various choices for this type of lens (Pentx vs. Sigma vs. Tamron), it seemed like this was, overall, the best buy and possibly the best lens.

          I have been happily surprised with just how good it really is, both as a versatile walkaround and with IQ in general. This lens rivals primes in some shots, is very versatile, and is a great value at half the cost of the Pentax lens. Recommended!

            Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

            I bought this lens because the Pentax DA* 16-50 arrived defective (not from BH). The focus was stuck at infinity, manual focus ring would turn but the elements did not move.

            I would like to have the weather resistance but was not willing to play the Pentax 16-50 lottery again.

            So I decided to try this sigma and after a few weeks of use am very impressed. It is such a handy lens for family events! It is fast enough to easily use inside without a flash and going to the wide end it works wonderfully for landscapes. The sharpness is crisp, colors are true and have not needed adjustment in post processing, and vignetting has not been an issue.

            Bottom line is that my standard go-to kit is my K5, this lens and my trusty DA* 50-135. This is a great combination that is easy to walk around with (just need a lens pouch and the camera on a strap) and you are ready for just about anything.

                This lens received very good reviews from Pentax Forums. Fast AF, excellent IQ make it a perfect replacement for your kit lens. Since I already own a compliment of 77mm filters for my DA12-24mm it was an easy decision to select this lens. Its my first Sigma and I'm very happy with my purchase. Of course, BH was great to deal with as always.

                The HSM is quiet. The optics of this lens is OK. I compared the bokeh of this lens with my Pentax DA* 50-135mm at f=2.8, the Pentax one's bokeh is significantly smoother than this Sigma. The biggest problem I had with this lens is the slow focus at 50mm when aperture is opened to 2.8. I have to shot a indoor wedding, the focus speed of this lens for sure cannot help me catch the most important moments for my clients. I return it in exchange for a FA 77mm limited.

                Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

                I got this lens because I sold all my da limiteds to go to a mostly zoom setup. So far, iq wise, I would say its better than the da 40 and about even with the da21 and da15. It's very usable wide open and is amazing stopped down. There does seem to be a fair bit of vignetting and ca though. The build quality is great aside from my copy being able to slightly rotate while fully mounted. I'm very happy that sigma decided to remove the os in these newer versions for the Pentax mount since it would be a bit redundant if they still had it. With the lack of os you don't have that mechanical "slosh" when you move the lens around. Overall, I'm very happy with this lens.

                  Bought this lens specifically for a trip to Italy,also took my Pentax DA*50-135 the Sigma stayed on the K5 90% of the time. It is sharp, quiet and fast, never missed a focus and was a joy to use.Combined with the K5 it was faultless in low light.Yes the zoom is opposite to the Pentax but that was no big deal..Only minor quibble is no red dot to line up lens to body..

                    Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

                    Excellent replacement for my kit lens. I use it for walkaround lens, high luminosity makes it possible to shoot handheld at night. I have owned for a week and found it excellent.

                    My Pentax 16-50 had some issues. I needed a sub and reviews touted the reliability and center sharpness of this walk around lens.

                    It has performed beautifully. The instructions told me to only put the lens on pointing down, use with OS off, and other quirks. Once I got over the guidance the lens has worked extremely well in a wide variety of situations and 100s of images.

                      fantastic lens, but difficult to focus on the pentax k-x. Better to use it in manual.

                      I purchased this to be my primary lens on my Pentax K5 and, for the most part, it has been an excellent choice. The build quality is outstanding. Only some annoying purple-fringing at 17mm keeps this lens from being 5 stars.

                        Comments about Sigma 17-50mm f/2.8 EX DC HSM Zoom Lens for Pentax DSLRs W/APS-C Sensors:

                        This is a fine "walk-about" lens, with a nice wide to slightly telephoto range. Others have pointed out that the focus ring turns when the lens auto-focuses, and that was a bit disconcerting at first. One other oddity is that the zoom range is "backwards", in that the 17mm wide setting is on the left of the lens and the 50mm is on the right, exactly opposite of my Sigma 100-300 f4.
                        The lens is solidly built and feels substantial. I don't find that it is too heavy on my Pentax K-5, and it feels well-balanced. The HSM focus is fast and accurate and silent as well; it is a joy to use!
                        Optically, the 17-50mm is very sharp, with a minor bit of blur in the corners. I have not seen any CA yet, and landscapes and street photos resolve nicely even at pixel peeping level. Colors are accurate and well-saturated as well.
                        I gave the lens four stars because of the focus ring issue and the minor corner issue. But I am very happy with this lens and it's a keeper.
