Sigma 18-35mm F/1.8 DC HSM Art on the web, hands-on previews and sample images...

While most of the previews are based on pre-production models, a small Korean web page posted several sample images taken with the new lens, mounted on both APS-C size cameras and Full frame  (Canon EOS 600D and EOS 5D Mk II)

DPreview hands on "Overall though the 18-35mm F1.8 is certainly an intriguing product, and we applaud Sigma for pushing the boundaries of lens design ahead of the more conservative camera manufacturers. It's a lens we think is worth investigating in more detail, and we'll be reviewing it just a soon as we can lay our hands on a shootable copy. Until then you can read more about the lens's design and operation on the next page of our preview."

Sigma 18-35mm F/1.8 DC HSM Art lens, the first zoom lens featuring f/1.8 throughout the entire zoom range

Press release: RONKONKOMA, NY, Apr. 18, 2013 — Sigma Corporation of America (www.sigmaphoto.com), a leading researcher, developer, manufacturer and service provider for some of the world's most impressive lines oflenses, cameras and flashes, today announced the Sigma 18-35mm F1.8 DC HSM Art lens, the market’s first zoom lens to achieve a maximum aperture F1.8 throughout the entire zoom range.

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, the 18-35mm is ideal for landscapes, portraits, still-life, studio, close-up and casual photography. . . . read more

DXO Mark almost a year after the release of the Nikon D800, publishes a four part review trying to discover the best lenses for the 36 megapixel beast

“Nikon D800 functions as Nikon’s flagship camera” according to DXO Mark, and it is currently the top camera on their Sensor Scores. The 36mp image sensor is an extremely demanding piece of photography both to the photographer and the lens. The resolution advantage is easily lost when it's not focused properly, or the quality of the lens does not meet the highest standards. Only when using lenses like the Nikon AF-S Nikkor 16-35mm f/4G ED VR, Nikon AF-S Nikkor 24-70mm f/2.8G ED and the Nikon 70-200mm f/4G ED VR  will get some decent zoom performance wile the best results will only come when using prime lenses like the Carl Zeiss Distagon 15mm f/2.8, Nikon AF-S Nikkor 85mm f/1.4G and will shine with the new Sigma 35mm F1.4 DG HSM.

"Announced in 2012, the Nikon D800 is the current undisputed king of DxOMark, with results that eclipse every other camera from all other manufacturers. However, with so much resolution on tap, the question is, which lenses should you use to make the best of what you’ve got? The DxOMark labs have tested 61 different lenses on the D800 to bring you an unparalleled resource of which lenses are best and which should be avoided. . . . read more

DXO Mark compares the best full frame 35mm prime lenses for the Nikon D800, and the winner is. . . .

This is not the winner

"After years of unadventurous, unexciting “slow” speed zooms “fast”, high-quality primes are experiencing a comeback thanks to the popularity of full-frame DSLRs and the merging of video capture. The moderately wide 35mm focal length has seen numerous new versions from most lens makers over the last two years or so, including this ultra-high speed offering from Sigma. . . . read more

Sony RX1 vs Canon 5D Mk III with Sigma 35mm f/1.4 sharpness comparison at the Photography Blog

Can't really understand the narrow focus or the scope of this comparison, but it is an interesting one, not many people get to have their hands on both these lenses at once :)

"The sharpness tests for this review were carried out using a real-world subject rather than a test chart. Both the Sony RX1 and the Canon EOS 5D Mk III DSLR / Sigma 35mm f/1.4 lens were mounted on a sturdy tripod. The camera's self-timer mode was activated to avoid camera-shake. Tonal and colour variances across the crops are due to changes in natural light during the session. Centre sharpness is very good from f/2.8 onwards on both the Sony . . . read more

First Look at the new Sigma 17-70mm F2.8-4.0 DC Macro HSM 'Contemporary series' lens at the Sigma blog.

The new Sigma 17-70mm F2.8-4.0 DC Macro Contemporary Lens review

Sigma's spectacular first entry in the 'Art series' family of lenses was the fabulous 35mm f/1.4 DG HSM, a lens that took the photographic community by storm. Having now set the bar very high, can the company repeat the success with the (soon to be released) comparatively cheaper and lower spec'd​ 17-70mm F2.8-4.0 DC Macro HSM​? Jack Howard​ writes:

"On APS-C cameras, the lens translates to about a 26-112mm zoom, which is a great everyday range for wide angle shots without significant perspective distortion, to short telephoto for flattering portraits. For the exact focal length equivalence, multiply your camera’s sensor format (1.5 to 1.7) times the focal lengths. . . . read more

Sigma 30mm EX DN lens for Sony NEX mount review at Photozone: Excellent performer, we know it, because we sell them....downunder!

I learned something today: Photozone.de now sells lenses...in Australia? Anyway, the Sigma lens seems to be an excellent performer, to the point of outresolving the NEX-7. I wonder how much better the new 'Art" series 30mm DN lens will be:

"The Sigma AF 30mm f/2.8 EX DN is capable of delivering an outstanding center performance straight from f/2.8 - it even broke the existing record for the Sony NEX 7 as of the time of this review. The lens is basically "diffraction-limited" in the image center so stopping down has no effect on the center performance anymore. The outer image regions reach a good level at f/2.8 and improve to very good (just) figures at f/4 to f/8. The overall performance diminishes from f/11 onward - this is a typical diffraction effect and no problem of the lens. . . . read more

Battle of the bokeh: Kai W checks out the full frame 35mm royalty, and some models too.

After Top Gear gets canceled, because of Jeremy's nth remark for verbally abusing minorities/foreigners/the Welch or whatever, I hope we'll see Jezza and Kai doing a Top Photo Gear program together, with explosions, tanks (lots of optics in these nowadays) and even more explosions!

Back to reality now, this time Kai gets his hands on the crème de la crème of 35mm lense$: The Nikon AF-S Nikkor 35mm f/1.4G, the Canon EF 35mm f/1.4 L USM, and the underdog that ate them all for breakfast, the Sigma 35mm f/1.4 DG HSM:

"The Battle of the Bokeh is back and we're looking at some fast 35mm lenses from Canon, Nikon and Sigma with the Canon 35mm 1.4L, Nikon 35mm G AF-S. This time, however, it's up to you to vote, and the video shows you the results of the blind-bokeh test. Which lens has the best bokeh?"

Wide-angle head-to-head: Sigma 14mm f2.8 EX Aspherical HSM vs Carl Zeiss Distagon T* 2.8/15 comparison at DXO Mark

This is a two-in-two test, the DXO Mark labs check out the Zeiss lens performance difference between Canon and Nikon mounts (5D Mark II vs D3x) and then pits the Zeiss versus the Sigma: 

"In DxO Mark’s testing the quality of the Zeiss lenses over the Sigma lens is very clear. A DxO Mark score of 17 for the Sigma lens is an OK score for a lens with this extreme wide angle: there are few wider corrected lenses on the market to cover full frame 35mm so if the lens were considered in isolation the score might possibly be accepted as a reasonable consequence of the focal length. However, when you look at the other lenses in this category the score does not look quite as good. Zeiss on the other hand have a shining DxO Mark score of 23 for their Nikon version, the highest for any lens of 20mm or wider with a Nikon FX mount (the Canon version scores a creditable 21). The Zeiss lens is much more expensive, nearly 4 times the price of the Sigma, so there will . . . read more

Sigma greatly expands its Art series lineup, announces 4 new entries: 3 Mirrorless and one Dslr lens.

Whoever thought the CP+ event would be a minor one-beyond the cheapo inexpensive digicam crap range, will have to rethink. We're to the tune of 9 new lenses announced so far, and Sigma contributes the heavy metal part: 4 new 'Art' series lenses, all made with Aluminum bodies and fitted with brass bayonets. You may recognize the Sigma 19mm F2.8 DN and Sigma 30mm F2.8 DN names, but the 60mm F2.8 DN lens is a totally new entity. All three lenses share the metal construction  and updated optics, come in silver or black color, and will be available in micro 4/3 and Sony E mount versions. They also share lack of information by Sigma regarding availability and price.

As for the fourth lens, its an update to the venerable 30mm f1.4 DC lens announced back in 2005. The newcomer is compatible with Sigma's USB dock, and completely overhauled, inside out. It will come in Sigma, Canon and Nikon mounts at an unknown date for an unknown price. . . . read more

5 reasons why you need an 85mm lens, at DigitalRev TV.

Panasonic Lumix G 20mm f/1.7 ASPH VS 30mm f/2.8 EX DN Lens sharpness comparison by Fredrik Gløckner

From my own findings, there's the issue of Sigma's much lower CA and purple fringing when used on Olympus bodies. In any case, the Sigma is an automatic buy anyway, due to its current very low price.

"We see that the Lumix G 20mm f/1.7 has an impressive level of sharpness, even wide open. The Sigma 19mm, on the other hand, needs a bit of stopping down before reaching the same level of sharpness. At f/2.8, the 19mm lens is a tad bit dull, even in the centre of the image frame. This finding is consistent with other tests I have seen. Generally, it is observed that the Sigma 19mm lens is not the sharpest at f/2.8, and improves when stopped down to f/4 and f/5.6. Stopping down beyond f/5.6 does generally not add anything to the overall sharpness, but does give you more depth of focus (DoF). If you need a deep DoF, it may still be wise to stop down to f/8 or even further, but this will give you slightly worse sharpness at pixel level.

The lenses on offer are the Sigma 19mm f/2.8 EX DN and the Sigma 30mm f/2.8 EX DN, available in micro 4/3 and NEX mounts. Their reviews have generally been very positive ones, and sure as heck they're worth their price. Most of the European dealers have updated their prices, in case you cannot find one, check this link on Sigma's page for a dealer list.

Sigma APO 70-200mm f/2.8 EX DG OS HSM lens review at Camera Labs: So, is there a situation where you should consider buying the Sigma 70-200/2.8? Well, yes! It's the cheapest way to get a stabilized 70-200mm zoom that offers a maximum aperture of f2.8.

Thomas Rubach tested the lens with a Nikon D800 body, a not so optimal solution, IMHO.

The Sigma 70-200mm f/2.8G OS delivers a decent overall performance, especially at focal lengths below 130mm. The center never disappoints throughout the focal range but the corners need some stopping down for good performance at focal lengths above 130mm. The resolving-power in the image-center is even good enough to use a tele-converter should you need to reach beyond the 200mm focal length. The image stabilization and the AF are OK but nothing to rave about, and a maximum magnification of around 1:8 and the size and weight does not differentiate this zoom from its competition. . . . read more

Sigma APO 50-150mm f/2.8 EX DC OS HSM Lens review by Bobby Zhang at the Phoblographer: At the popular 50-150mm focal range, this lens can be used for close portraits or for far-reaching sports, making it one of the more versatile lenses out there.

The Lens was tested with a Canon OS Rebel T3i/600D body. Kudos to Bobby for the intact EXIF information in his images.

"Designed for cropped sensor cameras, the Sigma 50-150mm OS works wonders when it comes to speed. At an awesome f2.8 aperture, this lens becomes much more flexible to fit your shooting needs and environment. Whether it is outside on a bright day or indoors in a poorly lit hockey rink, the images are clear and sometimes even surprisingly so.With a slightly higher $999 price tag, this Sigma lens costs much more than your average glassware but it is also appropriately priced. For the performance from the HSM and OS which combines to produce stellar images, it is difficult to not want one in your own bag. At the popular 50-150mm focal range, this lens can be used for close . . . read more

Sigma 19mm f/2.8 EX DN lens review by Jordan Steel at Admiring Light: I should't like it, but I love it.

Bokeh from the Sigma 19mm EX DN lens is relatively neutral.

The lens was tested with an Olympus E-M5 camera, and Kudos to Jordan for not stripping the EXIF information from the images.

"The Sigma 19mm is a lens that frankly, I shouldn’t like. I’ve been using pretty much nothing but high end lenses for the past 6 years, and generally a budget lens like this wouldn’t even ping my radar. Then there’s that somewhat odd focal length, it’s relatively slow aperture and unremarkable size . But the fact of the matter is, I do like this lens. Sigma managed to make an affordable lens that is well built with a fast and silent autofocus motor. They then made it . . . read more

Sigma 35mm f/1.4 DG HSM review at Digital Camera Review: If I were stuck on a desert island with only one lens and my camera, this would be it.

The Lens was tested by Chris Gampat using a Canon EOS 5D Mark II body:

Overall, not a bad thing can be said about Sigma's 35mm f1.4 EX. The company surely put a lot of time and effort into the design and it's worth every penny. The lens is sharp as a razor, a relative speed-demon when it comes to focusing, and has some beautiful image quality. It may even stay mated to your camera! If we really had to nitpick, we could talk about the lack of weather sealing; but then the $899.00 price point gets factored in. And that understandably keeps the price down. Personally, this is currently my favorite lens--I'm old school and was trained to shoot with all primes. If I were stuck on a desert island with only one lens and my camera, this would be it. Sigma's 35mm f1.4 EX wins my fullest . . . read more

Sigma 35mm f/1.4 DG HSM Lens Review at SLR Gear: There's a lot to like here: great results for sharpness, low chromatic aberration, and low distortion.

"Sigma's produced an excellent lens in the 35mm ƒ/1.4 DG HSM, with comparatively great performance at the ƒ/1.4 aperture setting, where the lens will no doubt be used for the majority of the time. There's a lot to like here: great results for sharpness, low chromatic aberration, and low distortion. There is some significant corner shading when used wide open, but coupled with the corner softness at the same aperture settings this contributes to an interesting look and subject isolation. If you're looking for corner-to-corner image sharpness you'll need to stop down. The Sigma 35mm ƒ/1.4 is definitely priced to compete, and designed to perform. . . . read more

Sigma 35mm f/1.4 DG HSM Lens Review by Mark Goldstein at the Photography Blog: We can whole-heartedly recommend the new Sigma 35mm F1.4 DG HSM as a fast, well-built prime lens that delivers superb results. Essential!

the Sigma 35mm F1.4 DG HSM lens was attached to a Canon EOS 6D body

Mark Goldstein tested this lens on a Canon EOS 6D body and went 'to 11' with his rating of this lens, giving it the unique rating of 'Essential' I also wonder where he tested it, since the lens seems dirty :)

"If the new 35mm F1.4 DG HSM lens is anything to go by, Sigma are definitely raising their game with the recent introduction of their three new lens ranges (Art, Sports and Contemporary). The Sigma 35mm F1.4 DG HSM is a fast and tack-sharp lens that exhibits low chromatic aberrations and very little barrel distortion. Vignetting at wide-open apertures is the only real optical issue of note, something that other fast lenses also suffer from, and stopping down to F/4 solves the problem altogether.

Sigma 35mm f/1.4 EX DG HSM Lens Review by Bryan Carnathan at The Digital Picture: The best lens Sigma has ever made?

"The Sigma 35mm f/1.4 EX DG HSM Lens, like all of Sigma's best lenses, uses HSM (Hyper Sonic Motor) AF. Autofocusing is internal and very quiet, making a light shhhh sound with some clicks being audible to the photographer if shooting in a quiet environment. Autofocusing is quick, though my perception is that the Canon EF 35mm f/1.4 L Lens focuses slightly faster when using both side-by-side.

Autofocus accuracy is of course paramount when making use of the great f/1.4 image quality with its shallow . . . read more

Sigma 35mm f/1.4 DG HSM lens worship at DP Review: If you're after a top quality fast prime at this focal length it should be right at the top of your short list, and it easily earns our top award.

"Sigma has produced some really fine lenses over the past few years, including the 50mm F1.4 EX DG HSM (which we liked a lot when we reviewed it in 2008) and the 85mm F1.4 EX DG HSM. But the 35mm F1.4 DG HSM may possibly be its best yet. In fact it's one of those rare lenses for which finding any fault seems almost churlish, so good is its overall performance.

Let's start with the optics. It's remarkably sharp, even wide open, outperforming not only its Canon, Nikon and Sony . . . read more

Sigma APO Macro 180mm f/2.8 EX DG OS HSM Lens review at PhotoReview: Buy this lens if you want a sharp and stabilized macro lens with a good working distance for photographing active insects and other small animals.

"Sigma’s APO Macro 180mm f/2.8 EX DG OS HSM is the fastest macro lens with a 180mm focal length currently available. Canon has an EF 180mm f/3.5L Macro USM lens but it's not stabilised and it was selling for more than AU$2000 (US$1580) when this review was written.

Tamron has a 180mm f/3.5 macro lens, which is also unstabilised and was selling for around AU$1350 at the same time . . . read more

It is 35mm day (Lens, not Film) at LensRentals: Canon EF 35mm f/1.4L & EF 35mm f/2 IS versus Sigma 35mm f/1.4 DG HSM resolution tests by Roger Cicala: No Canon can beat that Sigma.

This is a nice lens with a very nice IS system at a fairly high price

"Looking at the average (mean) for center, average, and corners shows a bit more about the lenses. The old 35mm f/2 does quite well in the center and mid-lens areas, but it’s pretty awful in the corners. The new 35mm f/2 IS and the classic 35mm f/1.4 L do much better in the corners, with the 35 L (stopped down to f/2) clearly better than the new f/2 IS. But the Sigma does better than any of them. . . . read more

Sigma 180mm f/2.8 APO EX DG OS HSM Macro Lens Review at Ephotozine: Sigma's new line of lenses on on par, if not better than 1st party manufacturers offerings, but so are also the prices.

Superb sharpness, even at maximum aperture, Effective optical stabilization.

"The Sigma 180mm f/2.8 macro lens costs around £1300 and offers optical stabilisation, silent autofocus with full time manual override and life size magnification at its closest focus distance.

If you can live with a slightly shorter focal length then Sigma also offer two 150mm macro lenses with a fast f/2.8 maximum aperture. One version also sports optical stabilisation and is considerably cheaper at around £690. A version without stabilisation is also available for around £600. . . . read more

Sigma 50-150mm f/2.8 EX DC OS HSM APO review at SLR Gear: Quite simply, one of the sharpest zoom lenses we have had the opportunity to test.

Sigma 50-150mm f/2.8 EX DC OS HSM APO without lens hood

"Sigma has a habit of identifying shortcomings in the lens offerings by other camera manufacturers and exploiting them: in 2006, with the introduction of the first 50-150mm ƒ/2.8 DC, it managed a coup, offering a 70-200mm experience for the APS-C camera. Sigma has certainly managed to improve on the initial and subsequent redesign of that lens, in the current optically-stabilized implementation. It's one of the sharpest telephoto zoom lenses we have ever tested, and should warrant serious consideration by photographers shooting with APS-C sensor-based cameras. Not only will you have . . . read more

How Sigma lenses are made at the Aizu, Japan Plant.

Sigma has posted a beautiful although slightly melancholically video that features some of the highlights of the lens manufacturing line assembly, interdicted with rural scenes from Japan. I could quite figure out the new lenses on the assebly block, looked like a 300mm f/2.8ish thingie.

Sigma 35mm f/1.4 DG HSM 'Art" lens action is gearing up, first impressions are very, very positive.

Welcome to the new Sigma, the one that no longer wants to be the underdog of lenses.

Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM review at DPReview: Best lens in the Dsrl travel ultra zoom game.

"The Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM fits the bill nicely; it's compact, has decent enough optics, offers fast autofocus and effective image quality, and tops this all off with impressive close-up ability. We'd be inclined to conclude that it's the best-rounded general-purpose SLR lens currently on the market." . . . read more
