Sigma 50mm F1.4 DG HSM 'Art' lab test report

The Sigma 50mm F1.4 DG HSM 'Art' is a fast normal prime for full frame cameras, with an unusually complex optical design. Its premium price tag of $950 / £850 makes it substantially more expensive than either its predecessor, or Canon and Nikon's 50mm F1.4 lenses. However Sigma's recent high-end offerings such as the 35mm F1.4 DG HSM and 18-35mm F1.8 DC HSM have been truly excellent, so how does the new 50mm measure up? See the lens test data and our analysis

The 50mm F1.4 DG HSM is Sigma's latest fast normal prime for full-frame cameras, and one of the most hotly-anticipated lenses of the year.

We've concentrated on large-aperture shots to show sharpness and bokeh, but have also included several taken at smaller apertures. See photos

Sigma's 18-200mm F3.5-6.3 DC Macro OS HSM | C is the latest version of its popular stabilized superzoom lens for APS-C / DX format SLRs.

A look inside Sigma's lens factory

Sigma gives us another behind the scenes look at their Aizu, Japan lens factory in a video released during the CP+ trade show. It's an artsy factory tour highlighting the craftsmanship and the process of how their lenses are assembled.

CP+ 2014: Hands-on with Sigma DP2 Quattro

We've never accused Sigma of lacking innovation, and while the Japanese manufacturer is best known for making lenses, Sigma also markets a line of cameras. The latest - the DP2 Quattro - features an all-new ~19.6 million pixel APC-C Foveon sensor and a completely new body design. Is this (in Sigma's words) a 'reinvention of camera'? We won't know until we've tried one out, but in the meantime click through for an initial hands-on look. 

Sigma unveils radical DP2 Quattro with re-thought ~19.6MP Foveon sensor

The latest, 45mm-equivalent, model features dramatic styling and a fundamental re-think of the company's Foveon multi-layer sensor design. The Quattro sensor still uses three layers to detect color information but now only captures its full, 19.6 million pixel resolution in the top layer, with lower two layers capturing 4.9MP of information each.

Where the sharpness comes from: A tour of Sigma's factory

Some people are happy to shoot with lenses and think only of the results, but it can also be fascinating to think about how such complex, precision pieces of engineering are made. Some insight is provided by Dave Etchells over at Imaging Resource, who has just posted a story about his visit to Sigma's factory in Aizu, Japan. However, no matter how hard you try, you can't make every lens perfect - as Lensrentals Roger Cicala explains in his recent blog post. Click through for more.

Need the speed? Sigma 18-35mm F1.8 DC HSM in-depth review

Sigma's 18-35mm F1.8 DC HSM has generated a lot of excitement since its announcement in April, as the fastest zoom ever made for SLRs. Designed for use on APS-C / DX format cameras, it offers a 28-54mm equivalent zoom range, and promises similar depth of field control to an F2.8 zoom on full frame. But can an F1.8 zoom really work? Read our detailed review to find out.  

Did Sigma design the Olympus M.Zuiko 75mm F1.8?

It's an open secret that many compact cameras are produced by OEMs - companies that produce large numbers of products that are then sold under other brand names. There are also consumer-grade zooms from big name manufacturers that look much alike (we know for a fact that third-party makers commonly create lenses for the bigger brands). But we were still surprised to read about Sigma's latest patent for a 75mm F1.8 prime lens...

DxOMark rates lenses for Pentax K-50, and reviews Sigma 50-500mm

Our friends and collaborators over at DxOMark have been investigating lenses for the Pentax K-50, and have just published an article assessing which score best on this well-featured little SLR. They've looked at 28 different models, from both Pentax itself and third-party makes like Sigma and Tamron, and given recommendations for the best lens to buy in various categories. This week they've also tested the Sigma APO 50-500mm f/4.5-6.3 DG OS HSM super-telephoto zoom, and compared it to the rather more expensive Nikon AF-S Nikkor 80-400mm f/4.5-5.6G ED VR.

Ditch the 'kit': Sigma 17-70mm f/2.8-4 DC Macro OS HSM 'C' review

Just posted: Our review of the Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C. This lens occupies its own little niche in the market, as an upgrade to the typical 18-55mm zoom that offers both usefully extended zoom range and a faster maximum aperture. It also includes Sigma's 'Hypersonic Motor' for silent focusing, and built-in Optical Stabilisation. In the latest of our lens reviews prepared in partnership with DxOMark, we see whether it should be top of the short-list for SLR owners looking to progress beyond their kit lens.

Sigma US announces Mount Conversion Service for recent lenses

Sigma has announced a 'Mount Conversion Service' for any of its recent 'Global Vision' lenses - a paid-for service designed to reduce the uncertainty of changing camera systems.

The results are presented in a multipart article, that also compares the EOS 6D results to those from the EOS 5D Mark III and the Nikon D600. Meanwhile for APS-C SLR users, this week DxOMark also reviewed two fast lenses from Sigma, the 30mm F1.4 DC HSM and (in case you missed it earlier this week) the 18-35mm F1.8 DC HSM.

We've just updated our preview of the Sigma 18-35mm F1.8 DC HSM with lens test data, courtesy of DxOMark.

Click through for a link to the article and for your chance to comment. 

Just posted: Our Sigma 18-35mm F1.8 DC HSM preview samples gallery

We've been lucky enough to get our hands on an early pre-production sample of one of the most anticipated lenses of the year, the Sigma 18-35mm F1.8 DC HSM, and bring you a gallery of full-resolution sample images shot with it. This lens is the fastest zoom ever made for SLRs and, in principle, should provide the depth-of-field control and low-light image quality on an APS-C DSLR that you'd get using an F2.8 zoom on 35mm full-frame. We've shot a samples gallery including a variety of subjects, using a range of apertures, focal lengths and subject distances, to try to give an initial flavor of how the lens performs.

Korean site publishes sample images from Sigma 18-35mm F1.8 DC HSM

We doubt very much that the site had Sigma's permission to publish the images from a pre-production lens, but if you're curious, you can click through for a link to the original 'preview' at lcap.tistory.com.

Just Posted: Hands-on with the Sigma 18-35mm F1.8 DC HSM

Just posted: Our hands-on preview of the Sigma 18-35mm F1.8 DC HSM Art lens. The announcement of the world's first constant F1.8 zoom caused a lot of discussion, much of it centered around the idea that the brighter aperture would help APS-C DSLRs to compete toe-to-toe with full frame cameras in many respects. We've had a chance to handle the lens and prepare a preview putting its capabilities in more context. Click here to find out more.
