Sigma has announced a compact 18-250mm F3.5-6.3 'Macro' superzoom lens for APS-C DSLRs. The latest version is an entirely new design, smaller than the existing lens and incorporating 'Thermally Stable Composite' (TSC) construction. TSC is a material currently used exclusively by Sigma, designed to minimize barrel expansion or contraction with extreme temperature variation. The lens will be available from July, starting with the Canon-mount version, with Nikon, Sony, Pentax and Sigma to follow.
Just posted: our review of Sigma's SD1 Merrill, the company's flagship 15MPx3 DSLR. The SD1 is the first camera to use the latest APS-C Foveon sensor, which detects three-color data at each location, giving what Sigma says is resolution equivalent to a 30MP conventional Bayer design. We've used both an original SD1 and SD1 Merrill, which are identical in terms of function and output, and the review reflects the behavior of the latest firmware for each. So does the no live view, no video SD1 deliver enough to carve out its own niche?
Sigma Corporation of America has announced the pricing and availability for its stabilized 50-150mm F2.8 APO EX DC OS HSM lens. The lens, designed to offer a roughly 70-200mm equivalent zoom range, will have a street price of $1099. The OS version of the lens is 46% longer than the existing, non-OS version.
Sigma has announced details of the promised support scheme for customers who bought the company's SD1 DSLR prior to the price cut. Buyers of the SD1 at the original price of $6,899 can claim 40 'points' that can be redeemed against other Sigma products. The points are worth up to around ¥400,000 (roughly $4800) when used against Sigma products at their MSRP on the day the SD1 price cut was announced. Customers have until May 31st to register for the offer.
We've been taking a closer look at the latest Sigma products, on show at the Focus on Imaging event in Birmingham, UK. A lot of the buzz at this year's show may be around the big new SLRs from Nikon and Canon, along with the Olympus OM-D E-M5 and Fujifilm X-Pro1, but Sigma is also quietly showing its recent announcements. The 15x3MP Foveon sensor-equipped DP1 Merrill and DP2 Merrill, along with the Digital Neo 19mm F2.8 and 30mm F2.8 lenses for Micro Four Thirds are all on show, so we decided to dig a bit deeper.
Sigma has totally reinvented its DP series of large sensor compacts with the DP1 Merrill and DP2 Merrill. The DP Merrill models are named after Dick Merrill, inventor of the Foveon sensor and include the most recent version of his technology - the 15x3MP APS-C sensor first seen in Sigma's SD1. Because the Merrill cameras feature full APS-C sensors, they also feature totally redesigned lenses, with the DP1M including a 19mm F2.8 lens to offer a 28mm equivalent field of view and the DP2M having a 30mm F2.8 lens to give a 45mm equivalent field-of-view.
Sigma's new CEO, Kazuto Yamaki has announced the re-branding and re-pricing of the company's flagship camera. The SD1 DSLR will now be know as the SD1 Merrill, in honor of Dick Merrill, inventor of the Foveon sensor technology on which it is based. The price will also be revised, falling to what should be a street price of around $2,299, which Yamaki attributes to work conducted to reduce production costs of the sensor. Despite these changes, his letter promises the performance and characteristics of the sensor have not changed. To avoid disappointing existing SD1 customers, Sigma will offer a support program with 'points' that can be exchanged for Sigma products.
It is with great sadness that we receive the news that Sigma's founder and CEO Michihiro Yamaki has died of liver cancer at the age of 78. Yamaki founded Sigma in 1961 and was still head of the company when it celebrated its 50th anniversary in 2011. In that time he took it from being a maker of converter lenses to one of the largest independent lens makers in the industry. His passion for photography also saw Sigma create one of the first large sensor compact cameras. Everyone at dpreview.com would like to offer our deepest condolences to his family at this sad time.
'We have to prepare a camera [for our loyal customers],' said Sigma COO Kazuto Yamaki when we spoke to him at the CES 2012 trade show. In the interview, he explained: 'I personally feel bad that some of our loyal customers couldn't [afford] the SD1' and promised that, in addition to making 'exciting' future products, the company would do all it can to reduce manufacturing costs. Yamaki also explained the approach it has taken with it Digital Neo lenses for mirrorless cameras. Click here to read the full interview.
Pre-CES: Sigma has launched the Digital Neo range of lenses for mirrorless interchangeable lens cameras, with the announcement of the 19mm F2.8 and 30mm F2.8 lenses for Micro Four Thirds and Sony NEX. The two relatively compact prime lenses offer 38mm and 60mm equivalent fields of view, respectively, on the Micro Four Thirds system and, 28.5mm and 45mm on the Sony E-mount. At F2.8, neither lens is spectacularly fast, but both systems benefit from the Sigma beginning to make mirrorless-specific lenses. Pricing and availability information has not been announced.
Pre-CES: Sigma has announced the APO Macro 180mm F2.8 EX DG OS HSM, an image stabilized telephoto macro lens. The company claims it is the first 180mm macro to combine 1:1 reproduction with an F2.8 maximum aperture. It offers a closest focusing distance of 47cm (18.5 inches) and includes the company's optical stabilization and 'FLD' fluorite-like glass elements. An internal focus design and ring-type HSM focus motor allow full-time manual focus override. Pricing and availability will be announced later.
Sigma is launching a non-stabilized version of its 17-50mm F2.8 EX DG HSM for Sony and Pentax. The lens replaces the existing OS versions for these two mounts, for which most cameras have built-in stabilization. The latest version will be available from December 9th. The Japanese recommended selling price remains the same as for the OS version.
