The 18-35mm isn't just sharp for a fast zoom; in terms of outright image quality, it's a match for many fast primes, even when shot wide open.”

Product Description

The Sigma 18-35mm F1.8 DC HSM Art lens for APS-C DSLRs is the world's first constant F1.8 zoom. The lens, designed specifically for APS-C sized sensors, covers a 27-52.5mm equivalent range, and is currently available for Canon, Nikon and Sony Alpha mounts. The 18-35mm offers the light-gathering and depth-of-field equivalent of a constant F2.7 on full-frame, which may under-cut the need for some photographers to change formats. The use of Thermally Composite Material (TSC) reduces size and weight but increases the lens durability. It is compatible with the Sigma USB dock for further customization. A 9-blade rounded diaphragm also creates beautiful background blur, and SLD glass compensates for aberrations and curvature. formats. Front and rear lens caps and lens hood are included with the lens.

    I'm usually a slow upgrader, waiting until at least a year after release, but with the Sigma 18-35mm f/1.8 I just went for it. First impressions: wow! This lens ... (1) ... is an APS-C equivalent to a full-frame 29-56mm f/2.8 lens (same shallow DOF and same light gathering ability). (2) ... can replace a collection of primes. (3) ... has better ...

    Sharp, Accurate, Fast Aperture, Great Colors & Contrast, Well-built...

    It is just what everyone else has said about it: sharp, accurate, fast aperture, well-built, great colors and contrast. I've also been very pleased with the focusing accuracy; it is infinitely better than my nifty-fifty. Focusing speed is decent, not lightening fast. Yes, it's heavy.  Feels fine on my Rebel (front heavy but not too front heavy) but it certainly takes some getting used too.  The weight seems appropriate for the very solid feel of the lens. CA is noticeable on the edges of the ...

    Nikon D7100 with Sigma 18-35 f1.8

    Lens is amazing, would be nice to see a bit more range. so far it has been on the D7100 since I got it last week. Focus is fast and hasn't had target issues. No issues with that on mine.  I like the size however it has a bit of weight to it, not used to that with my f1.8 primes. Will be trying it for video; with the zoom and steady f stop I think it will work out nicely.

    It is what it is

    This lens is most of everything that everyone says about it: it is heavy, it has a limited range, it does occasionally misfocus, and it is indeed SHARP and FAST.  You've all read the reviews, so I'll just add my personal experience and perspective. I got this lens because I wanted a professional-quality lens to add to my mostly mundane set of consumer-grade lenses for my Canon EOS 60D.  My consumer-grade lenses consist of a set of three zooms/superzooms/telezooms, the Canon nifty-fifty 1.8, ...

Questions & Answers


Sigma 18-35mm loose mount fit on Canon 7D?

I have the Sigma 18-35mm f/1.8 mounted on my Canon 7D, and what I have noticed when the lens is mounted, is that I can twist/wiggle the lens ever so slightly from side to side when it's fastened to the mount. And substantially more so than with my other lenses. It appears to be a bit "loose". The movement is minute, sure, but it's even more minute with my other lenses (a couple of Canons). Is this something I should worry about? My main concern is that this might add unneccessary stress or tension. I have not noticed that it affects usage or results in general, but it has become somewhat of an annoyance, because it just doesn't feel right. It should be a "tighter" fit, in my opinion. Because the zoom ring is quite firm (too firm for my taste, actually, but that's another story), I can feel the lens "twisting" inside the mount, if I use just a tiny bit too much force when zooming in/out. Perhaps, in time, it will loosen even more, so that it swerves even when not reaching the zoom ...

Canon 70D with Sigma lens...

Looking for anyone using the Sigma 18-35mm f/1.8 DC HS on their Canon 70D? If so, do you like it? How would you rate this lens?

1 month ago


I don't have it but it gets good rating for a somewhat unique large aperture zoom.  But I think the Sigma 30mm 1.4 (original) is a better value for low light shots, that's around $200 (used) Continue Reading

Is the new RayFlash universal Ringflash adapter Sigma-compatible?

I'm wondering, whether I could use this newly introduced RayFlash universal Ringflash adapter on the Sigma DP3M (possibly also DP1/2M, and also an old DP-series-cam), when supposedly using it in combination with the Sigma EF 610 DG Super flash. Would it also likely work on the SD1(M) when the new 18-35mm 1.8-lens is attached, in combination with that same EF 610 DG Super flash? I just haven't any clue whatsoever, which is why I'd happy, if someone here (or wherever really...) could tell me or at least attempt taking an educated guess on this matter. Thank you so much in advance for your truly valued and assumedly helpful replies ;-)

I don't think there's any way to tell without trying, but it looks very promising.   I may see if I can fine one at a local photography shop and see how it fits. Continue Reading

mike earussi wrote: Or you could use this one instead (it's a bit cheaper): and probably just as likely to work. Why?  The other one has adjustments to fit multiple flashes and bodies, the one you listed is specific to a Canon flash and a set of Canon bodies... Just looking at it I am almost certain it would not work on an SD-1 with an EF flash. Continue Reading

Thanks for the link, but this Amazon-thing looks nowhere near as refined and, if you like: high-end, as the original RayFlash. But thanks. Continue Reading
