Sigma 210-109 Overview

  • 1Description

The Pentax K-mount Sigma 18-35mm f/1.8 DC HSM Art Lens is a wide-angle to normal-length zoom that features a fast, bright constant f/1.8 maximum aperture. It is specifically designed for use with APS-C-sized sensors and provides a 35mm-equivalent focal length range of 27-52.5mm.

The lens integrates four aspherical elements into its construction as well as five Special Low Dispersion (SLD) glass elements to help minimize various aberrations and distortions throughout the zoom range as well as provide greater image sharpness and clarity. A Super Multi-Layer Coating has also been applied to lens elements to reduce surface reflections, lens flare, and ghosting to produce images with higher contrast and color fidelity. The lens barrel design is constructed from a Thermally Stable Composite (TSC) material that is akin to metal in texture and resistance to temperature and environmental changes while also remaining lightweight and compact. An internal focusing and zooming mechanism also helps to maintain a compact and consistent overall length and non-rotating front ring also better enables the use of circular polarizing filters. For control of focus, a Hyper Sonic Motor (HSM) is used to ensure fast, precise, and quiet focusing capabilities that are well suited to continuous shooting and movie recording.

Art Lens Line
This lens is part of Sigma's Art line; deeming it well-suited to creative image making due to its large, constant f/1.8 maximum aperture and ability to produce aesthetic bokeh by way of a nine-blade circular diaphragm. The range of focal lengths it covers, from wide-angle to normal-length, is nicely situated for everyday and artistic shooting applications.
Optimized Lens Design
Four aspherical lens elements, as well as the incorporation of five SLD glass elements, help to minimize the appearance of distortions and aberrations throughout the zoom range and provide clear imagery with enhanced sharpness. A Super Multi-Layer Coating also benefits the image quality by reducing reflections and flare and contributing to greater overall contrast and fidelity.
Hyper Sonic AF Motor
The Hyper Sonic Motor provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications. This AF motor can also be manually overridden at any time by rotating the focusing ring, giving you the ability to fine-tune image sharpness through manual focusing.
Other Lens Features
  • Constructed using a TSC compound material, this lens is lightweight while also exhibiting notable durability and resistance to environmental changes.
  • An internal focusing and zooming mechanism helps to maintain a consistent overall lens length and a non-rotating front ring facilitates more efficient use of circular polarizers.

    Sigma 210-109 Reviews

    18-35mm f/1.8 DC HSM Art Lens for Pentax K is rated 4.7 out of 5 by 528.
    Rated 5 out of 5 by from My new favorite lens! This is my first Sigma lens and I love it! The images are sharp and the lens is so much fun to shoot. Pros: Solid construction, heavy duty feel. The zoom and focus rings are extremely smooth to turn. Nice rubber grip adds to the solid feel. The lens never changes size, as you zoom or focus it all takes place internally. The images are very sharp. The button for auto/manual focus is nice and the included lens hood is great quality. Cons: This solid, rugged construction comes with a price, it is heavy, but manageable. In low light situations the autofocus does some hunting. Overall this lens is wonderful and I highly recommend it.

    Rated 3 out of 5 by from Sharp and fast... until it stopped working. This is the first lens I ever had to return to B&H. The second unit (replacement) just stopped focusing after four months of light use. I sent it to Sigma for repair under warranty. Second problem is also with the autofocus. I had to push the micro adjustment on my Canon 80D to the maximum at both ends of the zoom (18mm and 35mm) in order to get it to focus right. Any more correction and it would not have worked. If you are not familiar with the procedure for micro adjustments or your camera does not have the feature, forget about this lens. You HAVE to do it and make sure you select and de-select it every time you change lenses.

    Rated 5 out of 5 by from AMAZING LENS FOR VIDEO!!!!! This is a very versatile lens that offers a wide variety of filming options. The zoom is fantastic and smooth, and the focus is very precise. The best part about the focus is the range is wide, so you have the ability to be quite precise. The depth of field is shallow and creates a wonderful effect when pulling focus, but it opens up when doing a long/wide shot so it is easier to get a group or large object into focus. The construction is solid and durable. This is the lens to get if you are new to shooting video. I am not a photographer, so I can not comment on that. But I would imagine you would get great results with photography as well.

    Rated 5 out of 5 by from Not just hype My main use for this lens is to do video work, some landscape and street photography with a 7D MKII body. The sharpness of this lens is unbelievable, it puts my Canon L series 24-105 to shame plus has a much faster aperture! Two of the most common criticisms for this lens are its weight and autofocus issues. It isn't a light lens but that's not a deal breaker. It doesn't weigh a ton either. As far as autofocus, I mostly use manual even when doing stills. Though I did give the AF a go and had no problems, even in low lighting to nail the focus. This lens has convinced me that Sigma is a solid purchase for a much better price than comparable Canon glass.

    Rated 5 out of 5 by from Sharpest lens I have experienced I have realized what I have been missing since I got hold of DSLR. I had been wondering what difference does the lens make going from $ lenses to $+ lenses when every photographer in youtube points out. The photos taken from this lens is very sharp. Build quality is top notch. I was using 18-105mm Nikon earlier, i end up zooming in each photo. This Sigma 18-35mm is not a lot of zoom but makes you to move and use different perspectives which is important in photography. Long time amateur photographers having basic lens for so long and want to upgrade - this sigma 18-35 is the best. Just try it, you will love it.This lens is worth every $.

    Rated 4 out of 5 by from Love and hate What can I say? I love the built quality, the image it produces, best zoom lens in low light situation, great for wedding, awesome for video. I love this lens. However, I hate the inconsistency of its focusing with my 7D. I am not sure, but I wonder it's because of the contrasty nature of this lens, the camera thinks its in focus when it's not. That's just my theory. Its focusing works more consistently when your subject is closer, which is 95% of the situations I would use this lens for. If you, however, are having difficult time with its auto-focus, then use it in liveview mode, so far I have got 100% correct focus with lens in liveview mode.

    Rated 4 out of 5 by from GREAT GLASS! HOWEVER, BEWARE Now I want to start this review off correctly, this is a Sigma Art Lens, so, naturally, it creates stunning visuals and is a tank. It's a bit big, especially if you're putting it on any Sony (a7s, a7r, a6300, etc.) or Canon, or in my case the BMPCC. I'm using it with my Hoya UV IR 82mm filter along with my Genustech 82mm Eclipse Nd Fader Filter (Variable ND) and it seems to output some great images. Crip and I haven't noticed any vignetting with the filters on. All around, I think it's a solid piece of glass and if you are needing to zoom quickly for docs, weddings, or live events, I'd recommend using this alongside the Art 18-35mm f/1.8.

    Rated 5 out of 5 by from Perfect for low light shots of grandchildren I bought this lens December 2014 because my Canon 50mm F1.4 was not wide enough to photograph my grandchildren inside. I purchased this lens because of the wide 18mm and the F1.8. I love this lens. It is crisp and sharp. It lets me get great shots of my grandchildren, et al, in low light. It has great bokeh. I can get a lot closer to small subjects (flowers and insects) than I can with the 50mm F1.4. It is heavy. It does not have image stabilization, but the heaviness helps me to hold it steady. (I have trouble holding the 50mm F1.4 steady because it is so light.) I love it for macro shots, low light situations, and active grandchildren!

    i know this is for crop sensor. but will it work on full frame without a huge black edge around the image? this lens seems amazing!!
    Asked by: Anonymous
    From most all reviews I have seen, typically, everyone does state that the Sigma 18-35mm f/1.8 DC HSM Lens for Canon is an amazing lens as you mention. However, as the Sigma 18-35mm f/1.8 DC HSM Lens for Canon is designed for APS-C cameras, it should not be used on a full-frame camera. Trying to do so may damage the reflexing mirror in the camera or the rear element of the lens, or both, and as it is designed for the smaller APS-C sensor, there would be a black border around the edge of the frame where the larger sensor is looking at the outer edge of the lens' housing.

    I want to adapt this lens to my Sony fs5. Would it make more sense to order the EF mount version and use either the MC-11 or Metabones Mark4? OR.. Order it in the Sony A mount and then use Sony's A to E mount adapter? I believe Sony's native A mount of this lens won't go directly onto the fs5.
    Asked by: John
    You will get similar results whether you go Canon EF to Sony E or Sony A to Sony E adaptation. But, it is best to trust the results of the Sony to Sony functionality (eliminating a 3rd party product), so the Sony A mount to E mount adapter is recommended for the FS5.

    If used with the Speed Booster XL 0.64 on the GH5, what would this lens' FF equivalent be?
    Asked by: Anonymous
    With the Speed Booster XL 0.64x, the 50-100mm focal length would convert to a range of 32-64mm. Then, because it is on a Panasonic GH5 Micro 4/3 camera and sensor it would have an additional 2x crop-factor conversion to an actual effective range of 64-128mm when fully converted.

    If I were to use the 77mm Variable ND (by Tiffen) would I get vignetting?If it helps, I use the G85 with Metabones ULTRA 0.71 Speedbooster
    Asked by: Dallen C.
    You should not experience any vignetting.

    How is this camera for handheld video without the image stabilization?
    Asked by: James C.
    I have used this lens with my Panasonic GH4 and metabones adapter several times handheld. The heaviness of the lens makes it better for handheld shots as long as you hold it right. I use a little image stabilization in post with some of the resulting clips since the lens has no built in image stabilization. I love this lens and keep it on my camera for all low light shooting, Bridesmaids getting ready shots and wedding reception dancing.

    What is the best,meta ones model for this lens on a gh4
    Asked by: Rod
    The Metabones T Smart Adapter for Canon EF or Canon EF-S Mount Lens to Select Micro Four Thirds-Mount Cameras would be a great option.

    I understand that the 1.01 update for the d5500 disabled autofucus for many Sigma lenses, but the art I've heard sme of the art series lenses remain compatable, do you know if this is true?
    Asked by: BRIAN C.
    The only way to determine complete compatibility between a camera and a lens from a 3rd part manufacture is to try it out to see the results. The auto focus should work with this lens, but the only way to know for sure is to test it out to see the results. This lens is a returnable item if you are not happy with the results as well.
