The Sigma 18-35mm F/1.8 DC HSM Lens for Sigma is a wide-angle to normal-length zoom lens 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 one aspherical element into its construction as well as Special Low Dispersion (SLD) glass 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.
For updating lens firmware and fine-tuning its nuances to best suit your personal shooting, this lens is compatible with the Sigma USB Dock. The dock allows you to specify certain parameters and other settings through the Sigma Optimization Pro software, such as AF speed and focusing limitations.
I haven't found anything bad with this lens, outside the weight. It is great for those low light situations as well using it as a standard wide angle. I may have a chance soon, to use it for a interior design photography project. I can see the Sigma 18 - 35 will work great for that.
Great walk around lens very sharp
Things that are great about it very sharp
This lens is absolutely beautiful! The construction is amazing, the build quality is unreal, the glass is superb, the images you get with this lens are truly like no other. I'm currently using this on my Panasonic GH4 W/metabones speedbooster and it's hands down my favorite lens. Wildly shallow DOP and amazing looking bokeh. I love the fact that if you're like a foot off, you'll lose focus meaning this should be used primarily for closeups or super wide landscape shots. Personally I know everyone likes to use telephotos for closeups, but I find with wide lenses closeups really come alive especially with this Sigma lens. The ONLY gripe I have is that with the metabones adapter and this particular lens' weight, I feel like there is soooo much weight in the front of the cam that if I'm not careful the lens is gonna snap off haha, and that wouldn't be good. I use it handheld a lot for photos and video so that's one thing that worries me and you should be weary of if you're not using the mount this was built for (Nikon G). And I think its absolutely amazing that the aperture stays the same when zooming all the way in or out... the BEST feature about this lens! Other than that, this lens gets a 9/10 rating!
This lens just made me even more happier with my Nikon D7100 purchase this year and I feel it pushed the performance past the D600 in sharpness and now in low light ability. Sigma hit it out of the park with the 18-35mm F/1.8. It's totally worth the weight penalty. I'll carry this lens up any mountain and has made me pretty much feel confident to dump my primes, out of my bag. Still probably worth keeping them around, but they feel redundant. I also have a 17-70mm F/2.8 Contemporary lens and love it. Sigma is really stepping up their game and going high end at affordable prices. I probably won't own any Nikon lenses in 2014. If you shoot video with your camera, this lens is a must have. Did some candle light Christmas dinner recording and was blown over with the quality.
Love this lens. Just received it tonight and I can't stop playing with it. Build quality is solid, focus is silent, and good grief is it sharp! It's very heavy but I actually like that. It's also nice that no outer parts move when it focuses or zooms so you can hold it anywhere.
I have one on back order for my d7100 but I rented one a few days ago and all I can say is excellent lens. A little heavier than the plastic Nikon lenses but image quality more than makes up for it.
I just received my Sigma 18-35 F/1.8 zoom and it promptly payed it's way on a recent shoot. I spent a full day shooting candid action in a poorly lit auditorium, and came out with tack sharp images that would have been impossible with a slower lens. I've used Nikkor lenses for over 40 years, but the quality of this Sigma lens rivals the best that Nikon has to offer. As with all fast glass, the lens is as bit on the heavy side, but it will become a regular in my bag. I travel often and this will always be one of my travel lenses.
After waiting 3 months, the lens finally arrived! My Nikon 1.8 35mm has been my favorite lens, but the ability to shoot up close to my subject at 18mm was a much welcomed featured. The image quality and autofocus seem up to Nikon levels. Construction seems very solid. Complemented my D7000's nicely. Downsides? This is a monster lens and fairly heavy. Also, the 18-35 isn't a huge range, but for being the world's first zoom 1.8 lens, it's pretty impressive.
I have had it for a day now and have used it around for one shoot on my D7000. There was some back-focusing issues when it first arrived. Nothing AF Fine Tune -20 couldnt fix. Now its spot on and so sharp even at 1.8. The DOF on the lens is as smooth as a 50 or 85 even. It knocks everything in the background out. I would have never thought at 18mm you could get that smooth of a background. Focus is a bit slow. Slower then my Nikon 85mm 1.8G. But its extremely quiet. Sometimes I dont even know if it did focus because I couldnt hear it rack back and forth. Build is excellent. Everyone knows its super heavy and it is. Too heavy but it doesnt effect image quality. The zoom and focus ring are super tight as well. You have to give it a strong twist to get it moving. Great for videographers, not as good for photographers. The focus I dont mind being tighter but the zoom takes some energy to twist. I have also had it pre-ordered since 7/22 and just got it 11/12. One more thing, it zooms and focuses insanely close. Almost as close as my macro Nikon 40mm 2.8. Within a 4-5 inches.
