Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM

Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM is a fast full-time zoom for cropped cameras of various systems. I reviewed the version for Nikon DX cameras, so when buying such a lens, pay attention to which system it is made for. The lens is suitable for all Nikon cameras, even the simplest ones, without a focus motor.

Main technical characteristics of Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM:

Review Instance Name The following inscriptions are on the lens barrel, near the front lens 'Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM Ø 72 LENS MADE IN JAPAN', on the lens barrel 'Sigma DC 17-50mm 1: 2.8 EX HSM Optical Stabilizer'
Basic properties
  • DC (Digital Camera) - the lens is designed for SLR cameras with an APS-C sensor, in this case it is an analogue 'Nikon DX'

Production period C February 2010. In April 2013 augmented by a lens Sigma DC 18-35mm F1.8 HSM A (ART)

Sigma 17-50 / 2.8 is intended to be a relatively cheap replacement for 'native' lenses - Nikon AF-S Nikkor 17-55mm 1: 2.8G ED IF SWM DX и Canon Zoom Lens EF-S 17-55mm 1: 2.8 IS USM.

The Sigma 17-50 / 2.8 is a good weighty lens with a huge front lens that uses 77mm filters. The lens is made in Japan, the copy from my review does not have any obvious backlash, and the lens trunk does not spontaneously protrude. The lens has a metal mount and a special zoom lock at 17mm - 'Lock'. But from the side of the bayonet in the lens, you can see its entire electronic soul with boards, springs and other insides. I am concerned that access to such lens elements has not been blocked. And three more screws on the inner sections of the lens, which are located behind the front lens, do not look very good.

Sigma 17-50 / 2.8 - has fast auto focusalmost the same as the native Nikon 17-55 / 2.8... The high focusing speed is most likely due to the low travel of the focusing ring, which rotates only 45 degrees. I notice that virtually all of these third-party lenses 'save' on either the focus ring or the normal focus motor.

Auto focus is not only fast, but also enough silent. Noise level is several times lower than that of Tamron 17-50 / 2.8 и Tamron 17-50 / 2.8 VC, all thanks to HSM.

When focusing and zooming, the front the lens does not rotate, with filters should not be any problems. The focus ring and zoom are rubberized. During zoom, only one lens section extends. The minimum focusing distance is only 28 см, which will allow you to get macro pictures with an increase of 1: 5, which is pretty good for this kind of lens. Sigma 17-50 / 2.8 has a focus distance scale and a zoom position scale.

Bad that the lens does not support continuous manual focus control, but in order to focus manually, you need to switch the lens to the 'M' mode using the 'AF M' switch. Failure to do so could damage the lens motor.

The lens has a 7-blade aperture, which closes to a maximum of F / 22 over the entire range of focal lengths.

The lens comes with a wonderful case and lens hood. The hood can be worn back and forth, while maintaining low access to the focus ring, even 17 mm.

The inside of the lens. Several boards in two rows.

Of course, one of the main features of the lens is the image stabilization system, which allows take off at longer values excerpts... There is a special mode switch on the lens barrel - 'OS ON OFF'. I may be nitpicking, but generally stabilized lenses will freeze the jitter a little. JVIthat I did not see with this lens.

The instructions somehow incomprehensibly say that the stabilizer is powered by the camera even in the 'OFF' mode within a minute after turning on the camera or after pressing the focus and / or metering button exposure, or during the time while the metering is working. If you listen closely, you can indeed hear a slight noise in the middle of the lens, even with the stabilizer in the 'OFF' position. When you press the focus button, the noise just increases - apparently the stabilizer starts working at full power. This oddity can seriously affect the lifespan of a camera battery. I think this method of OS implementation is not logical. Stabilizer on the lens SIGMA C 17-70mm 1: 2.8-4 DC OS HSM MACRO works in a similar way.

Important: when the lens is removed from the camera, or when the camera is turned off, if you shake the Sigma 17-50 / 2.8 OS a little, you will clearly hear a noise in the middle, as if something had fallen off there. This is normal lens behavior, and the lens group responsible for stabilization is noisy, in the off state the lenses are not 'suspended' in the magnetic field.

In work, Sigma 17-50 / 2.8 proved to be quite good. Focus misses are rare, but still happen. The sharpness in the center of the frame pleasantly surprised me. But on the edges of the frame, everything is not so good, and vignetting in the wide-angle range on open diaphragms. And of course, strong barrel-shaped distortion of 17mm. If you close the aperture below F / 4.0, then it's a sin to complain about the lens.

The parameters shown in the photo gallery:
Everything is filmed on Nikon D80. EGF is 25,5-75 mm. On-camera JPEG L fine without treatment, reduced size to 3 MP. Everything was shot in N (Neutral) Picture Control. The long exposure noise reduction function and high ISO noise reduction function were turned off.

In general, I liked Sigma Zoom 17-50mm 1: 2.8 much more than its counterparts from Tamron, especially the quiet focus motor and the diameter of the front filter. The diameter of the filter, equal to 77 mm, is considered a professional standard, under which an experienced photographer over time selects a fleet of filters.

Sometimes, when working in the cold, the focus motor starts to buzz / whistle, and the focus itself can take much longer.


If you find a good copy of Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM, then such a lens will be an excellent staffer for every day and will even cope with more or less difficult tasks. The lens is attracted by a constant aperture value of F / 2.8 across the entire range of focal lengths, an image stabilizer, and fast and quiet auto focus.

Comments: 695, on the topic: Review Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM

  • Alexander

    Greetings to all. Please advise a fast lens (at a reasonable price) for shooting video on the Nikon D5100 (to replace the whale 18-55).

    • Arkady Shapoval

      like in this review

      • Alexander

        Something many here in the comments write that this lens is not very suitable for video.

    • Victor

      Yes, frankly, the d5100 itself is not very suitable for video))

      Yes, and Nikon itself as a whole (this does not apply to new mirrorless cameras from Nikon, and not very new ones either)

      • Alexander

        What do you recommend for video? Within a reasonable.

        • Anatoly

          If the priority is video for little money, then Panasonic is out of competition, there inside and out, even the cheapest ones will shoot better than Nikon. If money does not press then Sony 7m3.

  • Olga

    Please specify if anyone used the Sigma Zoom 17-50mm 1: 2.8 EX DC OS HSM (Nikon) lens on the Fuji X-series camera through the Fringer NF-FX adapter

    • B. R. P.

      Refine what?

  • Olga

    Please check reviews.

    • Dmitry Kostin

      Borrowed Fuji X-T4 with Fringer EF-FX Pro II adapter and Sigma AF 18-35mm f/1.8 DC HSM Art Canon EF-S lens. There was also a cell. The person used this system under video. AF work is not fast, but it will do for a photo - it suited me. The same adapter supports (if you google it) Sigma 17-50 / 2.8. How suitable the owner, I would advise you to test before buying.

  • Olga

    Have you met your expectations when shooting photos and videos after purchasing the Fringer NF-FX adapter. There are doubts that the Sigma 17-50 / 2,8 lens will perform worse in the Fujifilm X-T4 bundle than with Nikon. Included with Fujik is a whale XF 16-80mm 1: 4, is it worth buying an adapter and using a lighter lens (2,8) or the inability to use a stub in the Sigma lens (somewhere they wrote about it) simultaneously with an in-camera stub in the camera Fuji will not give any advantages when taking photos and videos?

    • B. R. P.

      Native is more reliable.

  • Olga

    More reliable what? Autofocus when taking a photo? Autofocus when shooting video? Or something else?

    • B. R. P.

      Autofocus, for all that, is more reliable with the native than with a third-party, and even through an adapter.

  • Olga

    Will F2.8 on Sigma 17-50 instead of F4 on native Fuja 16-80 give an advantage?

    • Victor

      Without specifying additional conditions, in the general case - it will.

  • Olga

    And if we take into account such a factor that through the adapter the Sigma 17-50 / 1: 2.8 lens on the Fujifilm X-T4 will be able to work either: 1) only with in-camera stabilization, or 2) only the stabilizer of the lens itself, but with the native Fuji 16-80 lens /1:4 - both stabilizations together? Can anyone elaborate? There are so many couch experts and silence everywhere

    • B. R. P.

      A person who used both lenses with this camera can interpret in a complex way. Provided that this person reads your post, is able to interpret and wants it. Moreover, the formulation of the question is not entirely clear, you are still looking for some advantages in the operation of the stub, aperture ratio. For serious work with video, external stabilizing devices are still used. Sigma nominally has an advantage in aperture ratio, but adapters and third-party lenses are a capricious thing and may not work properly with your camera. Aperture 4 of the native lens is quite working for a camera like yours. Try reading here: But you can't hide from sofa experts)

    • Victor

      You must understand that when shooting motion, the stabilizer is still unnecessarily and it is the aperture ratio that can fix it. And when shooting static, the best stabilizer is a tripod.
      In the video, as you rightly noted above, you can’t go anywhere without a steadic.
      In general, focusing on the nuances of the stabilizer is so-so ...

    • Victor

      Well, Christmas trees, fuja has a lot of other features
      – moisture protection
      - silent smooth focusing
      - noticeably smaller size
      - there are 16mm and 80 (instead of 50, this is significant)
      - overall better quality

  • Sergey Z.

    Arkady welcomes you! I was very surprised by this review! More precisely surprised by the photo, what color, skinton! I'm talking about Nikon D90! Here's the question, if it's not a secret, how did you illuminate the objects so that the skinton is perfect?

    • Arkady Shapoval


      • Sergey Z.

        Thank you! It is clear that experience. it's a pity..
