A lot of equipment passes through our Seattle and London offices, everything from high-end cameras to inexpensive accessories. A lot of it gets reviewed, but we can't cover everything. In this series of short articles, DPReview staff will be highlighting their personal standout products of the year. In part 4, Richard Butler discusses the Sigma 18-35mm F1.8 DC HSM and what it means for APS-C shooters.
Sigma has posted a statement on its website regarding incompatibilities between its lenses and the Nikon Df. As with the D5300, both autofocus and image stabilisation may not work correctly; however lenses without built-in focus motors are also affected when used on the Df. The company says it will provide free lens firmware updates to fix the issue, but this may not be possible with discontinued models. Click through for full details.
Sigma has posted a statement on its website regarding incompatibilities between its lenses and the Nikon D5300. Lenses with built-in focus motors may not autofocus correctly in Live View mode, and Optical Stabilisation (OS) may not work correctly. The company says it will provide a free firmware update for affected lenses to fix the issue, but this may not be possible with discontinued models. Click through for full details.
Sigma has released updates for its SD1 and SD1 Merrill cameras - as well as for its Photo Pro software - to add support for the recently released 18-35 F1.8 DC HSM lens. On the camera side, the SD1 firmware update improves color in peripheral areas of the image when the aperture is wide open. As for software, Sigma's Photo Pro v5.5.3 is now optimized for Raw (X3F) images taken with the SD1 camera and 18-35 lens.
Buried among all of the cameras announced last week was a new 24-105mm F4 DG OS HSM lens from Sigma. The company has announced pricing and availability for this full-frame 'Art lens', which will be available for Canon, Nikon, Sigma, and Sony mounts (in that order). You'll be able to pick one up for yourself starting next month at a retail price of $899. In the UK, the recommended retail price will be £849.99.
Sigma has announced the 24-105mm F4 DG OS HSM - an image stabilized normal zoom for full frame DSLRs. The 24-105 becomes the latest addition to the company's 'Art' series of lenses designed to offer high image quality. The lens features a 19 element/14 group design including Sigma's FLD glass and both single- and double-sided aspherical elements which the company says will minimize aberrations. It has a minimum focusing distance of 45cm throughout its range, giving a maximum magnification of 1:4.6. Prices and availability have yet to be announced.
Sigma USA has announced availability of the Nikon-mount version of its 18-35mm F1.8 DC HSM Art fast zoom for APS-C DSLRs. The Nikon version will retail for around $799, the same price as the Canon version, and will be available from November. We've been shooting with one for the past few days, and have put together a sample gallery of images showing what it's capable of.
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.
Sigma has announced firmware updates for two of its most recent lenses. Version 1.02 for the 35mm F1.4 DG HSM A012 (Canon mount) and version 1.01 for the 17-70mm F2.8-4 DC Macro OS HSM C013 (Canon, Nikon and Sigma mounts) bring improvements to autofocus operation and, for the latter, optical stabilisation. The lenses must be updated using Sigma's USB Dock, and owners should download the latest Version 1.1 of Sigma Optimization Pro software first. Click through for more details and the download link.
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.
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...
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.

Sigma has been doing lots of good things recently, and one of its most interesting recent products is the USB Dock. This device connects a lens to a computer and, in concert with Sigma's Optimization Pro software, allows the user to do such things as update the firmware and configure detailed autofocus microadjustment settings. In our quick review we take a close look at how it works and what it can do. Click through to find out more.
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 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 company says it will charge between $80 and $250, plus shipping costs, depending on the specific lens. The Global Vision range currently includes seven lenses - from the huge 120-300mm F2.8 DG OS Sport for full-frame DSLRs, down to the 19mm F2.8 DN Art for Micro Four Thirds. The company has also extended the warranties on all new products to four years (USA only).
Our friends and collaborators over at DxOMark have been investigating lenses for the Canon EOS 6D, and have tested no fewer than 95 lenses from Canon, Samyang, Sigma, Tamron, Tokina and Zeiss to see which score highest. 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. This lens has generated a lot of excitement as the fastest zoom ever made for SLRs, but the big question is whether its speed comes at the cost of optical quality. We've looked into this by comparing the 18-35mm to some current benchmark designs - and the results may surprise you. Click through to read all about it.
