Sigma Confirms Rumors: The 18-35mm f/1.8 is the Real Deal

Sigma Confirms Rumors: The 18-35mm f/1.8 is the Real Deal

You might have heard the rumors about a new wide angle zoom lens with a crazy open aperture of f/1.8. Those rumors have just been confirmed to us by Sigma: it's real and it's the first zoom lens to maintain an f/1.8 aperture over the entire length of the zoom range. Now that is exciting. Meet the 18-35mm F1.8 DC HSM Art lens.

The 18-35mm is the latest addition to Sigma's Art line (a categorization it shares with the critically acclaimed 35mm f/1.4). In case you were unaware, the Art designation is part of Sigma's new Global Vision. From Sigma: "The Global Vision lenses have a sleek new design with the manufacturing year stamped on the barrel, and are categorized by use into one of three groups: Art, Contemporary and Sports. The Art category delivers high-level artistic expression through sophisticated and abundant expressive power."

This revolutionary, wide aperture, standard zoom lens is created for DSLR cameras with APS-C size sensors, which translates to a focal range of 27-52.5mm on a 35mm camera. With a minimum focusing distance of 11 inches, and a maximum magnification ratio of 1:4.3, Sigma is calling the the 18-35mm ideal for landscapes, portraits, still-life, studio, close-up and casual photography.




The 18-35mm lens incorporates Sigma’s improved AF/MF switch and the use of Thermally Stable Composite (TSC) compound material, which has a high affinity to metal parts, consistently performs well at extreme temperatures and reduces the size and weight of the lens. It will also be compatible with Sigma's new lens dock that will be released later this year.

The lens has internal focusing and zooming, which prevents changes to the size of the lens (big points for this). Additionally, the front part of the lens does not rotate, so special filters like circular polarizers can be used.



The 18-35mm lens’ Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images, even in backlit conditions. The petal-type hood that is supplied with the lens will provide extra protection from flare and ghosting. Sigma’s Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function and the optimized auto focus algorithm results in smooth focusing and full-time manual focusing capability. Lastly, the nine-blade, rounded diaphragm creates an attractive, round bokeh at large-aperture settings.





Lens Construction: 17 elements in 12 groups
Minimum aperture: F16
Filter size: 72mm
Angle of view (SD1): 76.5°-44.2°
Minimum focusing distance: 11 in.
Dimensions (Diameter x Length): 3.1 inches x 4.8 inches
Number of diaphragm blades: 9 (rounded diaphragm)
Maximum magnification ratio: 1:4.3
Weight: 28.6oz

The only downside I can see from reading about the new lens is that it is only for APS-C camera bodies, a real bummer for those who use full frame cameras. But look at it this way: Sigma is totally capable of releasing something like this (like make a 24-70 f/1.8? Please?) for a full frame camera. Honestly, it's only a matter of time.

As of now, there is no pricing or availability released but we will let you know as soon as we hear from Sigma.

Hahahaha!! Best answer.

Mike Kelley's picture

Would pay $4k for this in a 35mm format.

That is a dangerous statement Mike :p

I had to vote you down man... don't give them ideas! lol

David Morrow's picture

why not save half that and get the 14-24mm f/2.8G if your a nikon dude that is.. best landscape lens on the planet:)

Jim Meyers's picture

The 17-35 2.8 is actually the best landscape lens on the planet b/c of the threaded front. Sorry. (affordable) GND's don't work on the 14-24. I've owned both.

Mort's picture

actually a TS is the best landscape lens. not some zoom lens.

David Morrow's picture

I guess I am wrong, the lens doesn't matter at all if the photographer behind it is shitty. So any lens is a good lens if you are a good photographer.

Call me a negative nancy, but I'm scared of Sigma.

I've heard nothing but stellar things about their 35mm f/1.4...and I imagine this will get rave reviews too. But I have a 50mm f/1.4 that keeps back focusing more and more everytime I use it.

Adam Cross's picture

then maybe you should go get that checked out ;)

Zach Sutton's picture

Yeah, although its a common problem among the 50mm f/1.4s....

So if I get it fixed, its only a matter of time before I'm paying Sigma to fix it again.

Adam Cross's picture

i'm sure you've tried already but can you not use micro adjustment to help with back focusing? (if your camera has micro-adjustment?) I've never had back focusing issues so i've never had the chance to use that in-camera feature

Zach Sutton's picture

Yep, its currently at a 19. Six months ago it was a 14. The more I use it the worse it any much more use, and it'll be unusable.

However, Sigma has seemed to really fixed its quality control problem with its new Art Line

I was scared too until I got both the new 35mm 1.4 and 17-70. Not scared anymore, stellar lenses. I can't wait to buy this lens!

I think a big thing Sigma has to overcome, and it is something that will take time is that this "new Sigma" is very different than the old sigma. They don't seem to be interested in making budget lenses that have decent optics but skip out on build quality.

Every lens under their new line has been arriving with stellar and amazing performance. I am VERY eagerly awaiting for them to update their 50mm F1.4 and 85mm F1.4 under their new design philosophy.

Jaron Schneider's picture

You're using an old lens. You can't judge new Sigma based on old Sigma :)

zach, everyone on the Canon forums who had focusing problems and sent their lens and body for calibrating to Sigma got their lenses back spot on. I did that for my 17_70 and 30mm.

Adam Cross's picture

just going to post a "hah!" to everyone online calling this fake and laughing about how ridiculous it is and that we're all stupid for thinking that a zoom this size could be a 1.8. hah.

I would be extremely interested if I still had my 7D

Dan Evans's picture

I was excited until I read DC. The 35mm 1.4 is the best lins that's ever been on my nikons. This would have been an instant buy if it were full frame.

oscar campos's picture

Wow! This is awesome.

BRAND | Photography's picture

we were made for each other.

make one for 4/3 please! (BMCC pocket cam FTW!)

Major W. Latimer's picture

So what you're saying is I should just start saving up now, because I'm for sure buying this lens!

Wilson Wong's picture

Goes to show APS-C has some life to it yet and I hate all that price premium just because it is a full frame! Honestly, the increase in image quality for Full Frame with the new processors is not that significant over APS-C with their new processors to justify the 2 fold increase in price for a DSLR.

X Mount please!!

Patrick Hall's picture

I agree....but photography snobs just sigh and complain it's not Full Frame. Heck I sold my D700 and bought a few D7000s a few years ago. I shot at least 1 full wedding season with DX cameras which worked out better than the FF cameras at the time (I couldn't afford 3 D3s cameras).

Grey Chen Junyang's picture

I think there is some legit concern over the fact that it is DX. Well I'll happily say that FX has a 2 stops ISO advantage over DX which makes the 1.8 no better than the 2.8 for speed. Larger sensor also negates bokeh advantages.

However, I wouldn't suggest getting a f1.8 FX zoom, cause... well it'll just be too damn heavy and expensive to be worthwhile.

The F1.8 DX in and of itself, pretty good but why the hassle when upgrading the body alone will make all the F2.8 lenses available F1.8 DX equivalent and let primes perform to their full potential.

For Nikon at least, all it needs to refresh its lenses are VR and bringing back the aperture ring. that'll then be perfect for video and photography. I'm currently using mostly AF-D glass cause (of $ and) there's just so much more control for every thing imaginable and I don't even shoot video yet.
