Sigma’s Super Zoom

leave a comment »

This Website is intended for photo-newbies, photo hobbyists and students and I try to include information that is relevant to that audience. But Sigma’s APO 200-500mm f/2.8 / 400-1000mm f/5.6 lens is way too cool to not mention.

With a price tag of $34,000 MSRP – yes, thirty-four THOUSAND dollars- it’s a lens out of reach for most hobbyists. Heck, it’s out of reach for most professionals too. So, why would someone want this lens?

Because sports and wildlife photographers often need a long-range zoom lens and with a f/2.8 maximum aperture at 500mm, this lens is hard to beat.

According to the Sigma Website, this ultra telephoto zoom lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. Special Low Dispersion glass and three Extraordinary Low Dispersion glass elements provide excellent correction for all type of aberrations. The super multi-layer coating reduces flare and ghosting and provides high image quality from the extremely large aperture. The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation. This battery is built in the lens barrel. For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens’ built-in LCD panel.

I guess we can all start saving our pennies now for this high-quality, well-made lens. Good luck and keep shooting!

I will often publish media releases related to photography on this blog in order to help keep you informed. These media releases are created by the respective companies. I edit the releases for space as needed.

The newest edition to the SD series of SLR cameras is powered by the 14 megapixel Foveon X3 direct-image sensor making it possible to capture all primary RGB colors at each and every pixel location and is arranged in three layers. The developing SD15 incorporates the “True II” new image processing engine. It provides high resolution power and reproduces high definition images, rich in gradation and impressive three-dimensional detail. Incorporation of the large 3.0 inch LCD monitor and improved processing speed provide ease of operation.

Since October 2002, Sigma has introduced three digital SLR cameras, the SD9, SD10 and SD14. In March, 2008, Sigma also introduced a high end compact digital camera, the DP1 which uses the same large image sensor as is featured in Sigma’s digital SLR cameras. They have established a strong following from a wide range of photographers, both amateur and professional. Photographers expressed a desire to incorporate the image processing engine “TRUE”, which is used in the DP1, into a digital SLR camera. In order to meet this demand, the SD15, with the high resolution direct image sensor, has been designed around the new “TRUE II” image processing engine. This combination delivers superior image quality as well as improved processing speed, operation and performance.

Sigma Pro Photographer David FitzSimmons at RTPI

I will often publish media releases related to photography on this blog in order to help keep you informed. These media releases are created by the respective companies. I edit the releases for space as needed.

Freelance writer, photographer, and Ashland University professor David FitzSimmons will share his visions of nature in an exhibit entitled “Wild Wetlands,” which will be on display from March 7th through April 4th at the Roger Tory Peterson Institute of Natural History in Jamestown, New York.

“Wild Wetlands” is a photographic journey taking a close look at shallow waters and watery lands. A walk through the gallery will allow visitors to envision wetlands like never before—seeing nature through the eyes of Sigma Pro photographer David FitzSimmons. Travel from muddy marshes to vital vernal pools. Frogs, salamanders, turtles, insects, and birds mix with wildflowers, trees, and other wetland plants.

According to FitzSimmons, “It’s an exhibit celebrating how healthy wetlands improve our lives.” These delicate natural areas, when cared for, he says, “provide cleaner water, ecological richness, and natural beauty.” Sixteen framed prints, including three unique round images produced with a circular fisheye lens, comprise the wetlands exhibit. The exhibition is co-sponsored by RTPI and industry-leading photography equipment manufacturer Sigma.

The Ohio-born FitzSimmons will offer a public slide program at 7 p.m. on March 12 in association with the exhibit. The program, entitled, “Ponds and Vernal Pools: Animals, Ecology, and Photography,” will explore the wet and wonderful worlds of ponds and vernal pools, showing secrets of their ecosystems and, according to FitzSimmons, “bringing you face to face with all kinds of interesting wetland inhabitants.” These include speedy dragonflies, dancing salamanders, and toe-biting water bugs. Drawing from work on two pond and vernal pool books, the freelance writer and photographer will stress the importance of experiencing, studying, and conserving these important habitats. David will also address two photography classes at Jamestown High School during his New York visit.

David FitzSimmons publishes international calendars with Barnes & Noble and BrownTrout, writes and photographs for magazines such as Popular Photography & Imaging, is at work on three books, and presents slide shows and lectures around the country, speaking about composition, natural history, and environmental conservation. FitzSimmons recently presented at the North American Nature Photography Association summit in Albuquerque, New Mexico, and later this summer he will conduct a macro photography workshop and open an exhibit at the National Center for Nature Photography. As an assistant professor of English, FitzSimmons incorporates photographs and natural history in his classes at Ashland University, Ashland, Ohio.

This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180°(154° for Sigma, 167° for Canon).
The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion. The minimum focusing distance of 5.3 inches, and maximum magnification 1:3.3 allows subjects to be as close as 0.7 inch from the lens’ front element.

This close focusing capability allows close-up photography and also it is possible to make use of large depth of field that covers wide range of subjects. The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring. This lens is supplied with a gelatin filter holder at the rear.

The lens is now available for Sony/Minolta digital SLRs, and Pentax digital SLRs.
The street value of the lens in about $1,000 US.

The Sigma Corporation is pleased to announce the launch of new SIGMA 18-250mm F3.5-6.3 DC OS HSM on March 10.

The SIGMA 18-250mm F3.5-6.3 DC OS HSM incorporates Sigma’s original anti-shake compensation function, with a 13.8 times zoom ratio. As opposed to having an anti-shake function in the camera body, this lens’s Hybrid Optical Stabilizer provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens.

Incorporating four Special Low Dispersion glass elements and three aspherical lens elements provides excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1: 3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood. Incorporating super multi layer coating reduce the ghost in the backlight photography.
