Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon

The high price and short focal length make Sigma's 18-35mm F1.8 DC HSM a niche lens, but it'll deliver high-quality images that justify the price.

  Terrific image quality., Wide f/1.8 aperture, Snappy autofocus

• -

  Short zoom doesn't do much., May be overkill for APS-C users., Flaky lens cap .

The Sigma 18-35mm F1.8 DC HSM is an extraordinary lens, offering prime-level image quality in the fastest zoom ever made for SLRs. Its 28-50mm equivalent range is a little limiting though, and inconsistent autofocus means that it can be difficult to make the most of the excellent optics when...

Ever since the industry-shattering announcement of the Sigma 18-35mm F1.8 HSM "Art," we couldn't wait to get our hands on a copy. Month after month of delays and pushed back release dates it finally arrived, and what an exciting time it was.

• +

  Constant F1.8 aperture throughout zoom range, Excellent build quality throughout the lens' construction, Large focus and zoom rings are perfectly dampened and easy to find and grasp, Capable of shallow-depth of field wide angle portraits, The only fast and wide angle solution for Pentax's many...

  Not weather-sealed despite excellent build quality and both internal zoom and focusing, Dreadful autofocus accuracy when using PDAF (looking through viewfinder), Bokeh can be jarring with highlights, producing "frog-egg" or "donut" ring bokeh, Stark color, temperature, and contrast shift from wide...

The word "groundbreaking" seems inadequate for describing the awesomeness of the Sigma 18-35mm f/1.8 DC HSM Art Lens. The primary reason for that awesomeness is the not-seen-in-any-other-zoom-lens f/1.8 aperture.

The Sigma 18-35mm f/1.8 is a true game changer. I may not be a technical guru, but I love to snap pictures. I use my camera every day, and am always looking for new, incredible equipment that enhances my ability to capture a moment.

The Sigma 18-35mm f/1.8 DC HSM lens is built for APS-C format cameras, providing a 27-52.5mm equivalent full frame field of view. At 1.78 lbs, the lens is not quite a bear; however, you’ll definitely notice an increase and size and weight from other variable aperture zoom lenses built for APS-C...

When the announcement of Sigma’s new 18–35mm lens arrived, some of our staffers chuckled upon opening the e-mail. Why? Because of what appeared to be a typo in the headline: Instead of f/2.8, it quoted f/1.8 as the maximum aperture!

Handling and features This much anticipated standard zoom lens for APS-C format cameras sports a fast f/1.8 maximum aperture throughout the zoom range and silent internal focusing with full time manual override.

The Sigma 18-35mm Æ’/1.8 DC HSM "Art" lens packs a big punch in features and image quality without a big punch to the wallet. Shockingly sharp images at all apertures, even at Æ’/1.8, with excellent flatness of field and good control over chromatic aberration, distortion and vignetting make this...

I'm a documentary filmmaker &I bought this lens for my Canon C100 Mark II. It's the worlds best lens of its kind, being F/1.8 and a zoom lens, it enables you to shoot footage that's amazing in low light which far surpasses any other lens I own.

This lens is SHARP! It's a must have lens for anyone does indoor photography. When it's wide open at F1.8, background blur (I refused to use the word bokeh; much like I now refuse to drink IPA. Both are sooo over used and abused) is soft ad velvety.

• +

  Good Build quality, Sharp, reasonable price, soft velvety background blur.

• -

  Bit heavier then I expected.

This lens enable high speed action to be photographed in low light situations. Whether I am shooting as The Digital Eye, LLC, or as a dad at a diving meet, when I cannot use a flash in low light - this is the lens.

This is a classy lens for APS sensor cameras in every way. Build quality is first rate with smooth zoom and focusing action. It is a perfect match for my Canon 70D (or a 7D) Image quality stopped down is razor sharp with virtually no distortion or vignetting.

• +

  Excellent build and image quality

• -

  One needs to use this lens with care due to the shallow depth of field.

Weather sealed and a quality low light art lens. This lens combined with a micro four thirds could make anything look cinematic. You'll be looking at other sharp lenses and wonder why they can't be this beautiful Sigma. I love Sigma glass. Sigma > Ziess any day.

its a great lens for rebel cameras, not so much for full frame unless you zoom into 24mm and up but other than that worth buying
