USB DockSigma's announcement of the USB dock was not something users anticipated, and even the most hardened industry analysts would have struggled to see this one coming without insider information. Now the £39 accessory is shipping in Canon and Nikon mounts, Sigma users with the new Global Vision range of S, A and C lenses are enjoying unprecedented access to their lenses' firmware and capabilities. One lens above all shows the benefit of the USB dock - the 120-300mm F2.8 S, and we've delved into the real-world advantages offered by the new system.

Many years ago Sigma countered the expanding SLR market by producing a lens range - the YS or "Yamaki System" - that used optical and mechanical components to allow the glass to be transferred between different camera bodies and mounts. As greater electronic communication and need to support the body systems and in-body AF motors of a new generation became essential, this wasn't necessarily practical.

With sophisticated electronics and in-lens motors for auto focus, however, it looks like a new, precision alternative has come up as Sigma UK announces a new service.


Mount Conversion Service. Only from Sigma.

SIGMA is going to start a new "Mount Conversion Service" which will enable Sigma to convert the mount of customers' Sigma Art, Sports and Contemporary lenses.

Development of a lens: The Sigma 17-50 F2.8 PDF Print E-mail

Sigma is unusual in the photographic industry for the amount of engineering and design that is purely in house. With the factory in Japan producing all of Sigma's lenses (and on occasion in the past, lenses for other firms as well) there is an absolute control over every stage of development. Now, under Sigma's Global Vision lens assessment and production is achieving even higher standards, with finished designs assessed using the A1 system based around the same Direct Image Sensor that gives the SD1 and DP Merrill range such sharp, accurate results.

The first lens to be released from this new design ethos, the 35mm F1.4, has gone on to critical and buyer acclaim alike, scoring unprecedented figures for a lens of that focal length and aperture, let alone cost. Yet Sigma's design has been heading towards this standard for years - and we've got an insight into the process behind the impressive 17-50 F2.8 EX DC OS HSM.

DP1m150pxSigma has announced new firmware for the DP Merrill series. The firmware, which reflects the versions of the cameras yet provides unified updates across all 3 bodies, can be found here:

  • Sigma DP1M - V1.04
  • Sigma DP1M - V1.05
  • Sigma DP3M - V1.02


・Improves the stability of operation.
・Improves the precision of bounce flash shooting when ELECTRONIC FLASH EF-610 DG SUPER SA-STTL and ELECTRONIC FLASH EF-610 DG ST SA-STTL are used.
・When you enlarge an image, it used to enlarge the center of the image. However, the new firmware magnifies the image depending on the focusing position.
・It is possible to select the file name of the image either from "SDIM" or "DP1/2/3M".
・It has integrated the color tones of Custom White Balance (Sunlight, Shade, Overcast, Incandescent, Fluorescent, Flash) among the DP Merrill series.
・Corrects the phenomenon that the AEL setting goes back to default if the AEL button is set for "Central AEL + AEL", and alternate MF to AF or vice versa, while it is still displaying the operation icon.
・Corrects the phenomenon that self-timer shooting whilst using P Mode would cancel the program shift for the customized shutter speed and aperture settings if you press the release button.
・Properly displays the image according to the selected magnification percentage.
・Corrects the phenomenon that the selected exposure is not appropriately applied when an external flashgun is used with Custom Mode.
・Corrects the phenomenon that, in rare cases, images are not recorded properly when the battery level is low.
・Corrects the rare phenomenon that the recording process does not go perfectly when the camera is turned off right after taking the image.
・It displays the size of the file when you select an image and open the Image Info Screen.

Small works of Art - Sigma's Micro Four-Thirds Lenses PDF Print E-mail

Art19mmSigma's Art series expanded into the mirrorless market earlier this year with new models of the 19mm and 30mm F2.8 DN series lenses. Whilst similar in focal length and aperture to the DP 1 and 2 Merrill bodies, these low cost optics are a different design, compatible with Sony's NEX and the Panasonic/Olympus Micro Four-Thirds format. A street price around £160 reflects the competitive nature of the mirrorless market, though with no direct comparison the Sigma lenses occupy gaps in the range offered by Olympus and Panasonic/Leica.




NEX users enjoy a 1.5x crop factor - we've reviewed the lenses on the popular Olympus OM-D body which features a 16Mp sensor, in-camera stabilisation and a 2x crop factor as with other Four-Thirds bodies.

An Alternative Process - Iridient Raw Developer 2.1 PDF Print E-mail

rawdeveloper icon lrgSigma's own software, Sigma Photo Pro, has been shipped with every camera Sigma has produced since the SD9 over a decade ago. Having introduced features like the X3 Fill Light that took full advantage of the Foveon's remarkable dynamic range, SPP has evolved slowly and whilst it remains a powerful tool for processing the X3F files produced by the Direct Image Sensor (and until the release of Iridient's Raw developer, the only option for the high resolution 46MP files captured by the SD1 and Merrill series cameras) it is limited compared to third-party offerings available to other camera users.

Iridient's application does not provide the catalogue and organisational power of Aperture and Lightroom, rather, it offers a nuts & bolts approach to editing raw files from almost any camera, with incredible control over curves and interpretation of the data alongside the valuable ability to crop, freely rotate and export files at any size in a variety of formats including batch processing.
