Sigma today announced new versions of the 50 mm F2.8 and 105 mm F2.8 Macro lenses. Both of the new lenses carry the EX DG notation have improved coatings and a new 'Floating Mechanism' to reduce aberrations. Both lenses are also 'improved for the characteristics of digital SLRs'. For improved macro depth of field both lenses have an impressive minimum aperture of F45 on Sigma, Canon and Konica Minolta lens mounts, F32 on Nikon, Pentax mounts.
Sigma today announced a new Lithium-Ion battery and charger kit for the SD9/SD10 digital SLR's. The kit consists of two rechargeable Lithium-Ion CR-V3 batteries (BP-11, 3V, 1160 mAh) and a charger, this kit is expected to retail for around £59.99 in the UK. It's not clear at this stage if any decision has been made to include this with the SD10 digital SLR kit but to me it would be a logical move and would at least bring the SD10 in to line with other digital SLR's from a power supply point of view.
Sigma today announced an all new 'DC' (Digital Camera) lens designed to be used only on digital SLR's with an APS (or smaller) sized sensor. The new 18 - 125 mm F3.5 - F5.6 DC lens has a non-rotating front element as well as a zoom lock button, it will initially be available for Sigma AF, Canon AF and Nikon AF-D lens mounts. Expected retail price in Japan will be 45,000 YEN (approx. $400), in the UK £229.99.
Sigma has today announced a new constant aperture wide angle zoom lens, the 24-60 mm F2.8 EX DG. This lens is designed to be compact but also 'fast' (large, constant maximum aperture) and to provide a usable zoom range for digital SLR users, on a Nikon digital SLR this lens would have an equivalent field of view of a 36 - 90 mm, on a Canon 1.6x digital SLR (10D, 300D / Digital Rebel, etc.) of 38 - 96 mm.
Just posted! Our full in-depth review of Sigma's new SD10 digital SLR. The SD10 is the successor to the SD9, it features a new and updated 10M X3 Foveon sensor which achieves higher sensitivity thanks to the addition of microlenses. There are also numerous other improvements to both the camera and Photo Pro RAW conversion software. See how the SD10 performed and how it stacks up to the current six megapixel digital SLR's.
Sigma today announced three new lenses, an all new 18 - 125 mm F3.5 - F5.6 DC (designed specifically for digital SLR's) as well as putting some official specifications behind their recently announced 4/3 System lenses, the 18 - 50 mm F3.5 - F5.6 4/3 DC and the 55 - 200 mm F4.0 - F5.6 4/3 DC. The 18 - 125 mm will be of interest to all digital SLR owners as it offers a small, lightweight 7x zoom capability. The 18 - 50 mm and 55 - 200 mm 4/3 DC lenses should also be of interest to Olympus E-1 owners but in my opinion hint more towards a more 'affordable' 4/3 System digital SLR coming from Olympus in the not to distant future.
Sigma today announced development of 18 - 50 mm F3.5 - F5.6 and 55 - 200 mm F4.0 - F5.6 lenses which will be compatible with the "Four Thirds System". The Four Thirds System was devised by Olympus as a new standard for lens interchangeable digital SLR's, it consists of a standard sensor size, lens mount and body to lens communication protocol. At PMA last month Olympus announced that Panasonic, Sanyo and Sigma had joined itself, Fujifilm and Kodak as the group of companies supporting the Four Thirds System. This is the first announcement from anyone other than Olympus who are producing compatible equipment.
Sigma has today announced a new version of its 17-35 mm F2.8-F4.0. The new version of this popular lens now utilizes a new type of Hyper Sonic Motor which provides full-time manual focus from the focusing ring. "We, Sigma Corporation, are the pioneer of the wide angle zoom. In 1979, we introduced the first wide angle zoom lens, "Zoom Gamma 21-35 F3.5-4". Since then, we've been leading the development of the wide angle zoom lenses. (1994/ 18-35mm F3.5-4.5, 1999/ 17-35mm F2.8-4, 2001/ 15-30mm F3.5-4.5 2003/ 12-24mm F4.5-5.6) We hope the customers can enjoy the improved performance."
Sigma Japan has today made Photo Pro 2.0 available for download (for both Windows and Macintosh). This will be great news for owners of the Sigma SD9 digital SLR as Photo Pro 2.0 can be used with RAW (.X3F) files from this camera as well as the new Sigma SD10 digital SLR. Our experience of Photo Pro 2.0 was very positive, image processing is improved, especially the handling of clipped color near highlights. In addition Photo Pro 2.0 has new features including the storage of processing parameters on a per image basis as well as the new X3 Fill Light.
We've just received our review Sigma SD10 (after a little mix-up with the courier) and I'm happy to report that resolution is identical to the SD9. I decided to test this immediately after we read reports elsewhere that resolution was significantly lower because of the use of microlenses. In our own shots of a standard ISO resolution chart we can measure absolutely no difference in resolution between the SD9 and SD10 using the same lens at (almost) the same aperture.
Sigma today announced the new SD10 digital SLR. The SD10 is a successor to the SD9, originally announced in February last year. The SD10 has an updated 10M X3 sensor from Foveon, the new sensor promises improved dynamic range, color response and sensitivity (thanks to the addition of microlenses). The primary differences between the SD9 and the SD10 are extended ISO sensitivity (up to 1600 in extended mode), longer exposures, a single battery power supply, 1/3 EV steps, wireless TTL flash support and image processing enhancements provided by Sigma Photo Pro 2.0. We have a brief preview and samples from a pre-production SD10. UPDATE: Imaging-Resource post full review.
Sigma today announced two new lenses designed specifically for digital SLR APS sensor size. The 18 - 50 mm F3.5 - 5.6 DC and 55 - 200 mm F4.5 - 5.6 DC lens can be made considerably smaller and lighter because they are designed to produce an image circle specifically large enough for an APS size sensor (all current digital SLRs except the Canon EOS-1D/1Ds and Kodak DCS-14n). Both lenses are notably lighter and more compact than 35 mm equivalents. Used on the Sigma SD9 or SD10 these new lenses would provide an equivalent field of view of 30 - 85 mm and 93 - 340 mm respectively.
