Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Pentax Digital SLR Cameras - Check it Out
 | Product Id : B002D2YYLY Category : Brand : Sigma Price : Rating :  |
Sigma Corporation is pleased to announce the new Sigma 10-20mm F3.5 EX DC HSM. This super-wide angle lens has a maximum aperture of F3.5 throughout the entire zoom range. With its wide angle view from 102.4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9.4 inches (24cm) throughout the entire zoom range and a maximum magnification ratio of 1:6.6. The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood and polarizing filter. The Petal-type hood blocks extraneous light and reduces internal reflection.

Outstanding lens
When I bought the Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras 14 months ago, I didn't know what to expect. I never used a 3rd party lens or an ultra wide-angle, but I quickly learned to love the lens and the opportunities it created. Having said goodbye to the lens a week ago (still kicking), I decided to give this new slightly faster model for a spin.
Currently reviews or even sample photos are sparse, and even some details seem elusive, so lets start in the beginning:
* Like the predecessor, this model features HSM, so all Nikon DSLR users can benefit from this lens (D700, D3, and D3x users will only get a cropped view)
* Also like its predecessor, its a hefty well-built lens that's made in Japan
* It's comparable in size and weight to the original, but the 82mm front threads take...
Excellent ultra wide people still don't know about.
I've owned this lens since February and it is my favorite lens for hiking. Using an ultra wide angle lens is a unique experience that comes with a steeper learning curve then most other ranges. The biggest concept to grasp is scale, at 10mm an object 1 foot from your lens will look like its 5 feet away through the viewfinder, so composition and corner to corner attention to detail is crucial to getting a good image.
Distortion at its widest is reasonable and expected.
It is incredibly sharp in center to mid frame wide open, but it can get a little soft on the edges. I own the Canon 70-200mm 2.8 IS USM II , so I know what sharp looks like and I have no gripes with this sigma.
Focus is quick and the rings have just the right amount of tension allowing for precise setting. Try laying on the ground and have a friend jump over you, ultra wide angle lens have incredibly large depths of field and it's hard for this lens to miss focus. Also the minimum...
Sigma 10-20 f/3.5 vs Nikon 16-85 3.5-5.6 VR II
I compared performance and test images taken with the Sigma 10-20 f/3.5 against my Nikon 16-85 VRII, which I consider to be my sharpest lens. The photos were taken with a Nikon D5000, tripod mounted, no digital sharpening, of fixed targets on my living room wall at about six feet. The targets consisted of newspaper at the corners and a large US map in the center, with a variety of detail and some color. Illumination was provided by house lamps and a photo flood light. The photos were compared side by side at 200% enlargement.
The Sigma 10-20 was not as sharp as the Nikon 16-85 in the very center of the image at comparable focal lengths (16mm and 20mm) and apertures, although was very close by f/5 and nearly the same at f/8. At the edges of the image however, the Sigma 10-20 was as sharp or sharper and had better contrast at all f-stops tested (3.5-8). I have no lens to compare the Sigma 10-20 to at shorter focal lengths but Imaging Resource tests indicate good to very...
