This lens is the master of Bokeh.

Beautiful tack sharp images with a bokeh background can be achieved with a bit of manual focusing.

In low light (shade and indoors) the lens produces amazing pictures without the use of a flash.

One of the fastest lenses I have ever used, action shoots can be frozen in time with ease.

This lens lives on my Pentax K20D and never fails to impress me.

The only reason I gave it 4 stars instead of 5 was that it does need a small bit of assistance with focusing from time to time and it is heavy... but worth it!

The lens has a wonderful bokeh and the colours are beautiful - but it has a bitter downside: The lens focused approximately 1/2 inch in front of the object (nearly too much for the camera - K20D - to compensate). Now it's on the way to SIGMA - and I expect them to fix it.
Some positive sides: The HSM is very fast, and you need nearly no light to make brilliant pictures. Also due to its full-frame compatibility there is barely any vignetting on APS/C cameras.
I would nevertheless recommend the lens - but be aware you might have the same problem to get solved...

      Excellent lens. Stopped at 1.4 you have to be careful with focus because the narrow depth of field is impressive! Great fast and almost silent lens. Will buy sigma again!

          Comments about Sigma 50mm f/1.4 EX DG HSM Lens for Pentax K:

          After reading all of professional and user reviews about potential focus issues, I hesitated over this purchase. Knowing that buying from B&H also meant proper support, I decided to pull the trigger ... Boy, am I glad I did.
          I spent the first hour testing the lens against my F50 f1.7, checked front/back focusing (now set to -2) and checked sharpness at all apertures.
          The lens passed all tests with flying colors, it met or exceed my expectations. I also love the hyper-sonic focusing ... I find it very quiet, fast and so far, very accurate.
          On my K20d with grip, it feels perfect ... one of the few lenses I've used that the balance just feels right.
          I also like the new finish much more than the old EX finish from Sigma.
          This lens is a definite keeper that is sure to become the lens I leave on the body.

            Comments about Sigma 50mm f/1.4 EX DG HSM Lens for Pentax K:

            I used this lens for portrait shots. I have taken a few that are perfectly in focus however close objects at 1.8-1.4 are not in focus(front focus). So i have chosen to replace it with a new one. B&H has great customer service, no questions asked! The lens feels great on my K3. Well balanced and is a great size. The throw on manual focus is rather short so shooting in AF mode is almost essencial. I would recommend this to anyone shooting pentax, its a far better build than my pentax lenses.

            Comments about Sigma 50mm f/1.4 EX DG HSM Lens for Pentax K:

            I sold my Pentax 50 to get this lens. I find the Sigma much sharper wide open than the Pentax. Lens is heavy for a 50 but I personally I like heavier lenses. Wonderful bokeh. I find the focus to be very fast and quiet. I also like the longer warranty.

                I'm a wedding photographer and I also shoot other events. Outstanding performance in low light. At 1.4 is a little soft but its very manageable. The optimal aperture is 2.2 and very sharp at 2.8. No signs of vignetting. Very quiet and fast focusing. At the optimal apertures, the images are razor sharp. Haven't found a dislikes yet.

                  You can read other reviews about autofocus speed, sharp images and color rendition. I wanted a system that would take photos indoors without a flash. Pair this lens with the Pentax K-5 and it does a wonderful job at it. I am able to take pictures of birthdays, holidays, new babies in the family all without a flash. I absolutely love it.

                  I have been using the Sigma f/1.4 EX DG HSM on both a Pentax K20D and K-5 with excellent results. I keep the aperture at 1.4 and adjust the shutter accordingly. As a portrait photographer, this lens is a must have. Being able to get crisp eyes while softening the nose and lips with the best bokeh around.

                    i know know, after buying loads of gear, over years, that the most important product in my bag (so to speak) is the photographer's eye. much more so than the sensor or the ISO setting or the ergonomic body. and after that - and a long way after that - comes the glass. the camera's eye. the sigma f/1.4 is the best prime i ever had for my pentax cameras. it's fast and sharp and serious, many things which i am not. it is a great lens. period.

                      I really enjoy this lens! I've been wanting a 50mm prime, and I had purchased another Sigma lens and love everything about Sigma. It's a joy to photograph with. It is a bit heavy, but I don't mind that at all. It has such a solid feel to it, and I like that.

                        Comments about Sigma 50mm f/1.4 EX DG HSM Lens for Pentax K:

                        Use this lens mostly for portraits. My copy seems to front focus quite a bit wide open. I have the K-5 AF adjustment set at maximum -10 which almost solves the issue (still ~2mm BF). I haven't found that to be an issue so far in real world shooting. Also, that's pretty negligible when stepped down.

                        The lens had some raving reviews which may have affected my expectations for its sharpness at f1.4. Plenty usable in my opinion. But I stick with 2.8 and up.

                        I love the weight and the size of the lens. Gives me better balance and grip on my K-5. It's a sharp lens, with a quiet operation. Bokeh is pleasing.

                        4 stars because of the BF, large filter thread, no weather sealing.

                        The lens has a wonderful bokeh and the colours are beautiful - but it has a bitter downside: The lens focused approximately 1/2 inch in front of the object (nearly too much for the camera - K20D - to compensate). Now it's on the way to SIGMA - and I expect them to fix it.
                        Some positive sides: The HSM is very fast, and you need nearly no light to make brilliant pictures. Also due to its full-frame compatibility there is barely any vignetting on APS/C cameras.
                        I would nevertheless recommend the lens - but be aware you might have the same problem to get solved...

                        First off it's a solid lens, a bit heavy but it takes a beating. Fast focus and quiet. I use it with k20 and I am very happy with the results. A must for low light photography.

                          Don't hesitate if you are considering this lens. Beautiful build, excellent IQ I have zero regrets with my purchase. I just spent a Sunday afternoon catching the last of the fall colors with my K7 and this lens, the results were superb in every regard.
