Sigma 10-18mm f/2.8 DC DN Announced: Ultra-Light f/2.8 Zoom for APS-C

By Alex Coleman 15 Comments
Published On October 5, 2023

Analysis

This is a very nice option for APS-C photographers and videographers. Compared to other options in this range, like the Sony 10-18mm f/4 or Sony 10-20mm f/4, this lens doesn’t weigh much more and captures an additional full stop of light. While not all ultra-wide photographers care about a bright maximum aperture, it makes the Sigma 10-18mm f/2.8 a more viable choice for Milky Way photography, videography, or other handheld low-light work.

For travel, having the full-frame equivalent of a 15-27mm is really practical. This lens also dovetails very nicely with Sigma’s existing 18-50mm f/2.8, making for a two-lens kit that can cover 15mm to 75mm equivalents at a bright maximum aperture for under 600g. If Sigma was planning this combo, however, I’d have loved to see these lenses share a filter ring size. Grabbing a 67 to 55 adapter isn’t the worst thing, but would have just been nice to avoid in the first place (and may have helped the vignetting issue on the 18-50mm).

Overall, this lens looks like a great option for APS-C photographers and a good choice for APS-C video, assuming that its performance is as expected. We look forward to testing it at Photography Life.

Press Release

This is the world’s smallest and lightest F2.8 zoom lens designed for APS-C format mirrorless systems at just 2.8 x 2.4 inches (72.2 x 62mm) and 9.2 ounces (260g)*. The lens covers a 15-36mm (35mm equivalent) focal range, with a fast F2.8 constant aperture. Paired with the 18-50mm F2.8 DC DN | Contemporary, this duo of lenses covers a 15-75mm (35mm equivalent) range with the same bright F2.8 maximum aperture at a combined weight of under 19.5 ounces (550g).

* As an AF F2.8 zoom lens for mirrorless cameras with an APS-C sensor. As of October 2023 by SIGMA. Figures are for L-Mount. Additional specifications included in the full press release below.

The SIGMA 10-18mm F2.8 DC DN | Contemporary uses an aspherical concave lens with a large polarization ratio and high refractive index in the first group, reducing the number of elements in the first group and shortening the overall length. Additionally, a new push-on petal type hood has been developed. Thanks to the new structure with a spring and lever, which is not utilized by any other manufacturer, the hood has been made both thinner and smaller, which also contributes to the overall compactness of the lens.

The optical design of the lens delivers a short 4.6 inch (11.6cm) minimum focusing distance and a maximum magnification ratio of 1:4 at the wide end, allowing for close-up photography with pleasing background separation. The optical design also minimizes focus breathing, and the stepping motor delivers swift, quiet autofocus during both still and video use.

Thanks to its high optical quality and compact size, the SIGMA 10-18mm F2.8 DC DN | Contemporary lens is an excellent choice for travelers, adventure photographers, vloggers, content creators, and family photographers who want great image quality when paired with today’s leading lightweight crop-sensor cameras on the three supported mirrorless platforms.

What’s up with Sigma’s arithmetic? “The lens covers a 15-36mm (35mm equivalent) focal range”. Uh, no, 10-18 on an APSC comes out to 15-27 full frame. Also, I think a comparison with the Fujifilm 10-20 ƒ/4 might have been interesting. That lens is a bit slower, but on the other hand it covers a slightly wider range and it is stabilized.

As I write this comment, I see:

• SIGMA Corporation, Japan
15-27mm (35mm equivalent)

• SIGMA Corporation of America
Full-frame equivalent zoom range of 15-36mm

Yes, and I am interested in locating the source of such errors. As with Nikon, most errors seem to be created by the US arms of the Japanese corporations.

Now, any idea what this means (because the words seem to be absent from the Sigma-global website)?

Yeah, Sigma’s press release on this lens was very weird. Here’s where they posted it and where we quoted from: press.sigmaphoto.com/produ…8-dc-dn-c/

Yes, that’s the website of the SIGMA Corporation of America. (I didn’t include URLs in my first comment because two or more would put the comment into moderation.)

I get the uneasy feeling that someone could be making the errors on purpose to see how far and wide they get propagated without question; like a self-propagating meme.

But it’s prudent to apply Hanlon’s razor:
Never attribute to malice that which is adequately explained by stupidity.

Is Nikon still in business ? And why ? Nothing bad about them per se, it’s just that their customers are usually old geezers whose peckers stopped working in 1990’s that love to comment about OTHER brands for literary no reason whatsoever other then being di**s ;)

This is an ordinary lens for a brick like camera body. Lovers of brick love that though ;-)

I used to own a Sigma 10-20mm for APS-C. It was a very versatile lens. The maximum magnification of 1:4 looks great also.

Yeah, this recent trend of lenses that are so multifunctional (expanded focal ranges, pseudo-macro, fast aperture, etc) is really nice to see. It almost makes comparison or analysis tough, because there’s a variety of good options in each niche.
