We're at the CP+ show in Japan this week and one of the busiest stands belongs to Sigma. Best known for manufacturing lenses, Sigma is showing off its latest camera, the dp2 Quattro. Editor Barnaby Britton sat down with Kazuto Yamaki, CEO of Sigma, for a chat about the Quattro, as well as the challenges of the modern photography industry and what it's like being the head of a family business.
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. They released a similar video during Photokina 2012 and have since gained some popularity with their higher end 35mm F1.4 DG HSM and the 120-300mm F2.8 DG OS HSM lenses. See video
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 has revealed the next generation of its DP series of APS-C sensor, fixed focal length cameras, with the dp2 Quattro. 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. The sensor will also appear in 28mm and 75mm equivalent dp1 Quattro and dp3 Quattro models.
CES 2014: Sigma has announced the 50mm F1.4 DG HSM | A, a fast 'normal' prime for full frame DSLRs. It will also work on APS-C / DX format cameras, offering a 75mm equivalent short telephoto effect. It's a completely new lens, rather than a revision of Sigma's existing 50mm F1.4, with an unusually complex optical formula for its type (13 elements in 8 groups). It'll come in Canon, Nikon, Sigma and Sony mounts; pricing and availability are still to be confirmed.
CES 2014: Sigma has announced the 18-200mm F3.5-6.3 DC Macro OS HSM | C, a superzoom lens for APS-C / DX format SLRs. With a 28-300mm equivalent zoom range, it's smaller and lighter than its predecessor, and has a shorter minimum focus distance. It will be available in Canon, Nikon, Pentax, Sigma, and Sony mounts; as usual the Pentax and Sony versions won't have optical stabilisation. Availability is still to be confirmed but Sigma USA has set a recommended price of $399.
Over the last few days a number of firmware updates have been posted. Fujifilm has new firmware for the following cameras: X-Pro1, X-E1, X-E2, and X100S. From Sigma, there are updates for the SD1 and SD1 Merrill. And finally from Pentax, the K-3 also has new firmware. Get download links and more information about each update. Learn more
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...
