Sigma is organizing a big day of news at Photokina. Previously, the lens manufacturer announced its intention to join Leica and Panasonic to further develop the L-mount full-frame camera system. At its press conference this afternoon, Sigma confirmed that in addition to L-mount lenses, she plans to market her own camera without a full-frame mirror.
Full-Frame Foveon
It is not a case of just stacking. Sigma cameras, like the current Sigma sd Quattro H, use sensor technology that is radically different from most cameras. The Foveon sensor has three layers, each of which is sensitive to a different part of the color spectrum. As such, it offers much more pixel detail than Bayer's designs. But the design is not widely adopted. Although it excels in image quality at the lower end of the ISO spectrum, we have not yet seen a Foveon chip that delivers good results when you move over 800 ISO.
Sigma plans to send his full-screen camera next year. This will be the first Foveon to offer a sensor size of 24 by 36mm.
Sigma will also cease production of the sd Quattro series, which uses the inherited SA SLR lens mount and abandons the development of SA cameras, but will continue to commercialize SA lenses and will offer an adapter for use with rim cameras L. He also plans to release a Canon EF-to-L adapter, similar to the Sigma Mount Converter MC-11. adapter currently sold for Sony E-Mount systems.
Finally, to meet the needs of existing customers, Sigma will also offer a mounting conversion service. This will allow you to use your current Sigma Global Vision lenses with an L-mount mirrorless camera without an adapter. No word on the lenses eligible for service, or how much it will cost to date.
New glasses
In addition to new L-mount, Sigma has unveiled five new lenses. One of them is the mirror-less Sony E-Mount APS-C and Micro Four Thirds cameras. The 56mm F1.4 DC DN Contemporary has a narrow viewing angle and a bright f-stop, making it an ideal choice for portraits. Its viewing angle corresponds to that of a full-size 85mm lens when paired with an APS-C camera, and its 112mm viewing angle on a Micro Four Thirds camera. The 56mm lens does not have optical stabilization. So you can associate it with a camera with an integrated stabilization system.
He is joined by a strip of full frame lenses. The 28mm F1.4 DG HSM Art offers photographers who think that a 35mm is too tight and a 24mm too wide a main f / 1.4 option. Protected against dust and splash, it has a fluorine lens coating to repel oil and water and promises to reduce sagittal coma, which is a big plus for night sky photography. It will be sold for Canon EF, Nikon F, Sigma SA and Sony FE cameras.
The following is the 40 mm F1.4 DG HSM Art. The 40mm is an under-represented focal length, but that many photographers consider a favorite – just a little more than a 35mm, but not as confined as a 50mm. It also promises a sagittal coma nix, shows less than 1% distortion, and of course gives you a fuzzy background by shooting at f / 1.4. This lens will also be available in the Canon EF, Nikon F, Sigma SA and Sony FE versions.
Moving on the territory of the zoom, event photographers will not fail to imagine the FMS.8 DG OS HSM Sports 70-200 mm. The optically stabilized zoom promises much better resolution than the existing 70-200mm resolution and is designed to withstand the rigors of professional use. It sports a magnesium barrel, extensive protection against dust and splash, as well as a fluorine coating on the front element.
The optical stabilization system is able to recognize and compensate for panning in any direction, so you do not have to manipulate the switches to adjust its behavior. Of course, Sigma also promises that the bokeh will be pleasantly smooth, so the lens will also appeal to portrait photographers. It will be marketed under Canon EF, Nikon F and Sigma SA media.
Finally, a new telezoom arrives on the Sigma range. The 60-600mm F4.5-6.3 DG HSM Sports offers a 10x zoom ratio, full screen coverage and a four-level optical stabilization system, although you need to switch from stabilization mode to panoramic with this goal. It offers a macro magnification of 1: 3.3 at a focal length of 200mm, which adds a bit of versatility beyond the power of zoom.
The barrel is a blend of magnesium, carbon fiber reinforced plastic (CFRP) and heat-stable composite (TSC), which makes it lighter than an all-metal model would allow. However, it's still a heavy weight of less than six pounds. There is also a weathertight seal and a fluorine front layer, as can be expected from a lens with the premium sports designation.
The 60-600mm is on sale in October and its price is $ 1,999. Pricing and availability of other objectives are not available at this time.
