The world's first lens to offer F1.8 throughout the zoom range.
Image quality so far is only found in fixed focal length lenses. A large aperture fixed focal length lens is ideal for achieving expressive bokeh effects and enjoying extremely high optical performance.
On the other hand, photographers often need to change the viewing angle to properly capture the presented scene. To solve this decades-long dilemma, SIGMA proudly presents the next-generation large-aperture APS-C size standard zoom lens 18-35 mm F1.8 DC HSM for digital SLR cameras.
Responding to the challenge of creating the world's first zoom lens to offer an F1.8 aperture throughout its entire range, SIGMA succeeded in creating a lens that delivers the same high optical performance as a fixed focal length lens.
These outstanding performance characteristics are particularly evident on an APS-C camera, as it has a slightly greater depth of field than a full-frame camera. This is a revolutionary lens that overturns preconceptions while expanding the range of photographic expression.
Constructed with the finest materials
Designed for the professional photographer
All lenses in SIGMA's new Art series come with a high-quality rubberized connection cover and feature a newly designed lens cover with an AF/MF switch, designed for intuitive use and superior functionality.
Inside, the HSM (Hyper Sonic Motor) mechanism provides high-speed AF and extremely quiet performance. An improved algorithm offers even smoother autofocus. Full-time manual focus override is another key feature that leaves the artistic touches in the hands of the photographer.

The best thing you can buy for studio photography with close-up full-body portrait shooting, the lens has incredible sharpness. It's worth every penny.
Excellent f/1.8 throughout the 18-35 range.
With sharpness from wide open.
Internal focusing and zoom does not change size, and has good response, natural in manual focus.
Classic video lens for APS-C & MFT systems, and also takes a booster
(where with a small adjustment it becomes parfocal) it just tends to vignette a bit at the wide end.
For video, it requires external audio because the focusing makes noise.
I can describe this lens in a few words... sharp, stable aperture, dog in the rain (I don't know about snow... yet), excellent quality, and there is no other lens in this category at this price. However, it has 2 to 3 negatives: a) quite noisy autofocus, b) lack of stabilization, and c) heavy (+positive when handheld movements in videos -negative when using a gimbal because you will need one that can withstand its weight)
The sharpness of this lens is incredible! I use it for both photos and videos and I am very satisfied with the result. The only downside is that for videos, the focus can be quite audible, so it's best not to use it with a shotgun mic but with a lav! I highly recommend it for both video (b-roll) and photography!
The video lens is worth every penny and more, with fast auto focus when playing with seconds, and top-notch manual. I have bought two and attach them to Canon. Simply the perfect combination for cinematic video. For those who want a smooth image and not the blur of mirrorless, it is the only way. On the face of Vlasis Papoutsis, you can see various projects attached to the Canon 70d
With the adapter on the GH5 VILTROX EF-M2 II, the autofocus is difficult, low light is great, sometimes there is a little vignetting on the edges in bright light, it makes the camera quite heavy compared to MFT lenses, it is worth it for professional use, if you just want it for a hobby, get MFT lenses because they are very lightweight and worth the money.
The lens is UNBELIEVABLE! The clarity in the photos is top-notch even at f/1.8! Sturdy and high-quality construction, like a tank. It has saved me even in difficult weather conditions. I'm not saying you should be under a torrential downpour, but it can withstand drizzles. I use it with a Nikon D7500. The autofocus is very good, I haven't noticed any issues, even in low-light shots. Although I have the Sigma adapter, I didn't need to use it to adjust the focus.
In night shots, which is its strong point, on the D7500, with ISO 800 and aperture at f/2.0, the shutter speed comes out at 1/40. It's enough to prevent blurry photos. The other positive aspect is that it's practically 3 prime lenses in one. So, you don't need to constantly change lenses on the camera.
The only negative is its weight, but even that is relative. If we compare it to Full Frame lenses, then it's lighter. If you have it on the camera and you're shooting all day, it might get a little tiring, but the photos make up for it. They can't be compared to kit lenses.
Luckily, there is this lens to fill the gap in Nikon, which is unacceptable since the lineup for Dx cameras is incomplete.
I have him in Nikon 7200, he is an AMAZING lens compared to the Tokina 11-20 that I have. The colors, contrast, and sharpness of the Sigma are incredible. No issues with autofocus, the only negative is the limited zoom range. If it reached 50mm, it would be perfect
I used the lens on a Nikon D7200 body.
Advantages: Sturdy construction (although it is prone to scratches due to its matte finish), strong contrast, vibrant colors.
Disadvantages:
- The autofocus never worked accurately (you can only notice this issue when comparing one-to-one in Lightroom). I also purchased the dock to adjust the focus accuracy, but even after spending countless hours (the adjustment process is very difficult), the results were not consistent. This single disadvantage rendered the lens useless for any purpose as the photos were blurry (this was more noticeable in Lightroom).
- Completely useless at f/1.8 (the focus accuracy issue was even more significant at f/1.8). It was also extremely soft at f/1.8 (it produced good results in terms of contrast, etc. at f/5.6, but the focus was still not accurate).
- Heavy and bulky (which is expected due to the glass elements).
- No VR (Vibration Reduction).
- Strange focal range on crop sensor bodies (27-52.5).
- Quite expensive for what it offers (with the same amount of money, you can buy a used full-frame camera or an exceptional lens for a full-frame camera).
In general, before making such an investment, if possible, try and test the lens because there is an issue with Sigma lenses on Nikon bodies regarding focus accuracy (I had the same issue with the Sigma 17-50 on the D3300, D7000, and D7200). My personal experience: after using all the above-mentioned bodies and dozens of lenses, I tried a Canon 6D with the 40mm STM 2.8 lens. I was amazed by the focus accuracy compared to Nikon bodies (I have previously purchased the Sigma 17-50, Nikon 55-200 VR II, Tamron 70-300, Nikon 35mm, and Nikon 85mm. For some reason, the results are never consistent on Nikon bodies when it comes to focus accuracy with the above-mentioned lenses (except for the Tamron). Some bodies work well, while others don't. All were purchased brand new. A professional or someone who has extensively used different bodies and lenses will immediately notice this issue. An amateur might not notice it.
I'm simply saying that you should try it out for yourselves before making a purchase (borrow from friends, acquaintances, rental stores, etc.). I hope everyone is well and happy shooting.
The best lens for APS-C cameras on the market and the only zoom lens with an aperture below 2.8. Ideal focal length that works incredibly well for both wide shots and portraits at 35mm (APS-C 52mm). Sharpness that is out of this world. Even wide open at F1.8, the lens's sharpness remains incredibly high, even at the edges of the photo. Fast and precise autofocus, simply focus and shoot. Very sturdy and heavy with amazing build quality, like all the Sigma Art Series lenses. The only negative I see is the size, but it doesn't bother me at all, in fact, it gives the camera a "professional" look.
Positive:
Extremely sharp, built like a tank, perfect autofocus (Canon 80D dual-pixel AF) and focuses very close.
Negative:
Autofocus makes noise (microadjustments - mainly noticeable in videos), lacks stabilization, is very heavy (I personally find this positive though).
I have been using the lens for about 2 months now on a Nikon D5200. The main reason I got it was because I was looking for a bright lens for night photography (astrophotography, galaxies, etc.). The results were beyond my expectations, but the most pleasant thing was that it ended up becoming my main everyday lens, despite its admittedly small zoom range. The only minor drawback is its weight, which can be tiring especially for everyday use.
For use in Video with DSLR CANON mainly. Amazing sharpness and brightness. Ideal for difficult lighting conditions. Quality construction. Its weight is large compared to kit lenses. It's worth every penny until the last cent! An investment in quality upgrade that doesn't exist in any other lens in its category! I highly recommend it.
