Sigma Corporation has announced the launch of the new 17-70mm F2.8-4.5 DC MACRO
lens, an ideal large aperture standard zoom lens for digital SLR cameras featuring
an APS-C size image sensor. The lens has a minimum focusing distance of 20cm
(7.9") throughout the entire zoom range. Maximum magnification of 1:2.3
enables close-up photography like a macro lens. The new lens design and multi
layer lens coating reduces flare and ghosting. A Special Low Dispersion (SLD)
lens and two aspherical lens elements provide excellent correction for all types
of aberrations and produce a high level of optical performance throughout the
entire zoom range.
Sigma Corporation of America is pleased to announce the availability of its new Sigma 18-250mm F3.5-6.3 DC Macro OS HSM lens starting in July 2012. Pricing is still pending. The addition of the 18-250mm F3.5-6.3 DC Macro OS HSM speaks to Sigma’s versatile product lineup with this multipurpose zoom lens that offers Optical Stabilization (OS)* and covers wide angle to telephoto to macro photography. It differs from Sigma’s current 18-250mm F3.5-6.3 DC OS HSM lens with its even more compact size, its macro capability with a maximum magnification ratio of 1:2.9 and the use of Thermally Stable Composite (TSC), material currently used only by Sigma.
If you ever want a unique point of view try a "fisheye" lens. Like
looking through a door peephole (which in fact is a "fisheye" type)
this order of lens sacrifices linear correction in favor of a very wide angle
of view. Originally made for creating "full sky" images when pointed
straight up, they had long ago been adopted by photographers for creation of
decidedly different points of view, and, today, even doing QuickTime movies
to display the interior of a condo or vacation home.
The Sigma Corporation is pleased to announce the launch of the new 4.5mm F2.8
EX DC Circular Fisheye HSM lens. Features include:
· The first 180 degree circular fisheye lens designed specifically for
APS-C size digital SLR cameras
· Fast F2.8 maximum aperture making it ideal for low light photography
· Minimum focusing distance of 13.5cm and a maximum magnification of 1:6
· SLD glass minimizes color aberration
· Equipped with HSM with full-time manual focus override
· Equisolid angle projection method is possible for art and scientific
This autofocus circular fisheye lens has an angle of view of 180 degrees in
all directions. It is exclusively designed for digital SLR cameras with the
APS-C size image sensor. When used in conjunction with digital SLRs with APS-C
size image sensors, it produces a circular image within the frame. The F2.8
large aperture value produces a bright image in the viewfinder and allows photographers
to take pictures in low light conditions, making it an ideal lens for Astrophotography
and Aurora photography. Due to the quantifiable angle/area relationship it produces,
this lens can be used for scientific and arts applications such as solid angle
measurements of cloud distribution over the sky or vegetation distribution of
the forest. The minimum focusing distance of 13.5cm/5.3inch and maximum magnification
of 1:6 make it particularly useful for close-up photography. SLD(Special Low
Dispersion)glass provides effective compensation of chromatic aberration. Sigma's
Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with
an inner focusing system that creates high definition and good image quality
over the whole frame. The HSM(Hyper Sonic Motor)ensures fast and quiet autofocusing
and allows full-time manual focus override by rotation of the focus ring.
The 50-150mm F2.8 APO EX DC OS HSM telephoto lens is the successor to the 50-150mm F2.8 APO EX DC II HSM. The updated lens now features Sigma’s own proprietary Optical Stabilizer (OS) technology, which offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The lens design utilizes an inner-focusing and inner-zooming system that provides convenient handling and this, along with the OS feature, makes it favorable for high-performance, handheld, close-up photography. Additionally, the Hyper Sonic Motor (HSM) ensures quiet and high-speed auto focusing, while allowing full-time manual focus capability.
Sigma Corporation has announced the launch of the new 50-500 F4-6.3 EX DG/HSM lens. This high zoom ratio lens is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. This ultra-zoom lens employs a seven-group zoom system, which provides a high zoom magnification of 10x. Triple-cam Rear Focusing System ensures high precision throughout the whole focus range. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration. A zoom lock switch eliminates 'zoom creep' during transportation, a convenient addition when traveling. The HSM Hyper Sonic Motor models provide quiet high-speed AF function, as well as full-time manual focus capability., The rear focus mechanism produces a non-rotating front lens element which accepts a bayonet "Petal-type Hood", which prevents extraneous light from degrading the image quality. By adding an APO teleconverter (sold separately), you can use this lens as a 140-700mm f/7.3-8.8 MF ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 200-1000mm F10.4-12.6 MF ultra-telephoto zoom lens with a 2X teleconverter. Teleconverters can be used in 100mm – 500mm focal length range.
Sigma Corporation has announced their new 500 F4.5 APO EX DG HSM lens.
This ultra-telephoto lens has a fast maximum aperture, and also features a new super multi-layer coating, which optimizes the characteristics of digital SLR cameras.
Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.
Sigma Corporation (www.sigmaphoto.com) is pleased to announce the new 70-300mm F4-5.6 DG OS lens. This compact, telephoto zoom lens provides an extremely long zoom range that can capture an array of subject matter spanning from portrait to sports photography. In fact, with smaller chip cameras from Canon, Nikon, Sony and Pentax, this large-aperture lens’ focal length grows to the equivalent of about 105-450mm.
Sigma Corporation of America (www.sigmaphoto.com) is pleased to announce that the company’s 85mm F1.4 EX DG HSM lens is now available for purchase in the United States for the MSRP of $1,400 and the estimated street price of $899.
The new and updated Sigma lenses include the 30mm F1.4 DC HSM, which will be available in Sigma, Canon and Nikon mounts, and the 30mm F2.8 DN, 19mm F2.8 DN and 60mm F2.8 DN lenses, which are available for both Micro Four Thirds and Sony E-Mount camera systems. Pricing and availability on all of these lenses has yet to be announced.
Sigma has announced the restructuring of the Sigma lens lineup into three new categories, the launch of a new lens in each of those categories, the development of a new quality control inspection and measurement system for the lenses, and the design of new software and a USB docking station that will enable photographers to update and adjust their lenses to suit thier personal preferences.
zoom lens covers a telephoto range up to 500mm and allows photographers to bring
the subject close and short perspective. Sigma's original OS (Optical Stabilizer)
function offers the use of shutter speeds approximately 4 stops slower. It is
ideal for sports, wildlife and landscape photography with handheld shooting. Three
SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic
aberration. This lens is equipped with a rear focus system that minimizes fluctuation
of aberration caused by focusing. The super multi-layer lens coating reduces flare
and ghosting. High image quality is assured throughout the entire zoom range.
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed
AF as well as full-time manual focusing capability. The addition of the (optional)
1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto
zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively. A
removable tripod socket (TS-31) is included as a standard component.
