Sigma Japan has announced a new wide angle zoom lens, the 12 - 24 mm F4.5-5.6 EX DG HSM. This lens is clearly aimed at providing a good wide angle range for digital SLR's as well as ultra wide angle for film SLR's. On the Sigma SD9 (1.7x crop) this lens would provide the same field of view as a 20-41 mm lens, on the Canon EOS-10D/300D this would be approx. 19-38 mm. This new lens will be available in Sigma, Canon, Nikon, Pentax (non-HSM) and Minolta (non-HSM) mounts and has an estimated Japanese list price of 99,000 YEN ($901 at todays exchange rate).
Sigma Japan has today announced a new lens. The 24 - 135 mm F2.8 - F4.5 will be available for Sigma, Canon , Nikon, Minolta and Pentax lens mounts, it has a 77 mm filter size, 50 cm (19.7 in) minimum focus distance and weighs 530 g (17 oz). This lens will no doubt be interesting to digital SLR owners because of its relatively wide angle 24 mm, on the Sigma SD9 this lens would provide an equivelant field of view of approx. 41 - 230 mm, on the Canon EOS-10D approx. 38 - 216 mm and on the Nikon D100 approx. 36 - 203 mm.
Sigma has announced new SD9 firmware and a new version of Sigma Photo Pro will be made available for download next Wednesday, 14th May. The new firmware and Photo Pro combination deliver improved noise reduction, improved processing speed and the primary concern of SD9 owners higher quality JPEG images from Photo Pro. JPEG files from Photo Pro are now saved with the 4:4:4 down sampling when the quality is set to 7 or higher, the previous version of Photo Pro used 4:2:0 down sampling which could lead to loss of color resolution and odd color artifacts.
Sigma Japan has posted a recall notice for the 'battery case' (the cartridge which slides into the base of the camera) for cameras with a serial number between 1000251 and 1000459. This is to correct a fault where the amount of remaining power is incorrectly reported when using NiMH batteries, this problem does not occur with Lithium CR-V3 type batteries. The notice states that only the battery case need be returned and new cases will be supplied in return. It's not clear yet if this range of serial numbers affects any cameras outside of Japan.
Phew! A review that took quite a bit longer than I had expected. The Sigma SD9 is the first digital SLR to utilize Foveon's revolutionary X3 sensor. The X3 sensor is the first image sensor capable of capturing full color (RGB) at each pixel location. The SD9 is based around Sigma's SA9 film SLR and has all of the normal SLR functionality you would expect, the SD9 takes Sigma SA mount lenses, writes images in RAW (.X3F) format onto Compact Flash Type I or II cards. See how the SD9 did in our tests and comparisons.
Dave Etchells over at Imaging Resource has today posted his review of Sigma's SD9 digital SLR which is the first digital camera to use the revolutionary Foveon X3 sensor. "The Foveon technology is impressive but not perfect, and I fully expect a holy war to erupt on the 'net over the issues of color purity and image noise with the SD9. Supporters will point to the SD9's excellent capabilities, good resolution, and affordable price, while detractors will call attention to its substantially higher than average image noise in the red portion of the spectrum and maximum shutter time limitation. Mixed into the fray will be arguments over subtle aspects of the "look" of images derived from a sensor with full-color pixels." The SD9 is currently second in our queue of cameras to review (out of six here awaiting review). UPDATE: Some comparison shots posted.
Thanks to forums poster 'Andreas P.' for noting that seven new Sigma SD9 samples have been posted on the German website Foto Erhardt. These samples were taken during Photokina under studio conditions (on the stand probably) and are Copyright Sigma. Several of these images show the huge potential of the X3 sensor and its ability to deliver very fine single pixel resolution. Kudos also to the Photographer who I assume is the same as was doing the demo on the Sigma stand.
Photokina 2002: UPDATE: At last the sun is shining here in Cologne so we ran back to the Sigma booth and grabbed an SD9. These images are far more representative of what we had hoped and expected from Foveon's X3 technology and really show what an amazing step forward it is. I'm very happy with these images, and am looking forward to a full and final review of this camera sometime in October. UPDATE: Added more information about RAW converter, re-converted images.
Photokina 2002: In addition to the huge interest surrounding the SD-9 Digital SLR Sigma has also introduced three new big zoom lenses at the Photokina show. These are the APO 80 - 400 mm F4.5 - 5.6 ES OS, APO 120 - 300 mm F2.8 EX IF HSM and the APO 300 - 800 mm F5.6 EX IF HSM. The last of which would provide a huge 1360 mm when mounted on the SD-9! The APO 80 - 400 mm is the first Sigma lens to feature image stabilisation.
PMA 2002: Yesterday we had an exclusive hands-on with Sigma's SD9. As we all know the SD9 will be the first digital camera to utilize Foveon's new X3 sensor technology. The SD9 digital SLR is fitted with a 3.54 x 3 million pixel X3 sensor which produces a 2268 x 1512 x 3 image (captures RAW in-camera). The SD9 has a Sigma lens mount (which may well be it's Achilles heel) and a host of manual controls which you'd expect of a D-SLR at this level. The SD9 is set to retail for US$3,000. UPDATE: Added image of dust protection filter.
Sigma has today announced a new AF 20-40mm F2.8 EX DG lens. Again this lens appears to be aimed at owners of digital SLR's because it offers a relatively useable bottom end (wide end) to a normal mid point in a compact lens construction. For example, this lens on a Canon EOS-D30 would provide an equiv. range of 32-64 mm, on a Nikon D1x it provide an equiv. range of 30-60 mm. The lens has access at the back for filters.
Here's an interesting snippet of news courtesy of our friend Yamada Kumio. Sigma will soon introduce a new AF 15-30mm F3.5-4.5 EX DG lens, this lens is of most interest to those users of digital SLR's because it will offer them zoom lens with a decent wide angle bottom and usable 'normal' telephoto. For example, this lens on a Canon EOS-D30 would provide an equiv. range of 24-48mm, on a Nikon D1x it provide an equiv. range of 22.5-45mm. The lens comes with the hood attached and access at the back of the lens for filters.
