Product Description
Sigma provides the new ultra-wide angle zoom lens from 15mm and this lens is the first of its kind in the world. It can be useful for images of landscapes, large buildings, group photographs or even more. The perspective that changes with the angle-of-view gives picture an extraordinary feeling. Delicate compositions can be adjusted by lens zooming and this is helpful for close-up photography. Provides deep depth of field with its short focal length for amazing photographic expressions. This ultra-wide zoom lens covers a large wide-angle range from 15 mm to 30 mm. With a minimum focusing distance of 30 cm(11.8 inches) throughout the entire zoom range, it is an ideal lens for Digital SLR Cameras. It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration. Minimization of the distortion is a most important issue for zoom lens, but Sigma has succeeded, to provide image quality with minimal distortion by employing aspherical lenses. This lens in corporates an internal focusing system, which eliminates front lens rotation. Since focusing do not change its overall length, this lens is easy to hold and use. Also it is allowing the use of a Petal-type Hood. The lens also incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens.

Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras Reviews
| 284 of 290 people found the following review helpful  I didn't plan on buying this lens but I am glad I did, By Craig 1959 "RAV Fan" (Ottawa, Canada) - See all my reviews This review is from: Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras (Camera) I went into a local camera store to look at the Nikon 12-24mm wide angle zoom to eventually augment the Nikon 50mm 1.8 and 18-200mm VR I currently use on my D200. After seeing the Sigma 10-20mm, taking test shots with it and the Nikon, and then printing the shots in the store, I walked out with the Sigma lens.I had planned to buy the 12-24mm Nikon next Spring when my budget would allow the expenditure. I have had success with Nikon optics in the past - starting with my first Nikon FM back in the seventies. The Sigma's good construction, nice finish, smooth+fast+quiet focusing and 10mm focal length convinced me to try my first non-Nikon lens in 30 years. A big factor: The Sigma lens is less than half the price of the Nikon lens here is Canada. It fit my budget, so I took the plunge. The Sigma fits into my "sharp enough" category. In real world shooting, its sharpness is on par with my 18-200mm Nikon. Both lens are less sharp than my $100 50mm 1.8 when...

Read More:, By Amazon Verified Purchase This review is from: Sigma 10-20mm f/4-5.6 EX DC Lens for Pentax and Samsung SLR Cameras (Electronics) I am rating this lens with only three stars because I am reviewing two lenses. Here is why:When I received my lens I later realized that I did not receive the extended three year warranty card that comes with the USA versions of the lens. Instead of just sending me the extended warranty card Amazon shipped me a whole new lens. Now while I was reading reviews prior to ordering this lens I had seen many reviews where the reviewer either loved this lens or they hated it. After a while I could see why... Some of the lenses that are being shipped are sharp all the way around while some are not sharp at all. Many claimed it was sharper at F:8 than F:4 while others said theirs was never sharp at all. Some complained about distortion and or dull or over saturated colors. I finally found a reviewer who had the opportunity to try 3-4 different lenses. They found that there seemed to be a lack of quality control all around when it came to this specific lens. Having a few...

Of these, sigma 12-24 is the only one which is usuable on a full frame sensor (canon 1d, 5d, possible future cameras). There is sizable difference in field of view between the 10 mm, and 12 mm. and the tokina is closer to 13 mm on its wide end. The sigma retails for about 2/3 the price of the canon. Optically they are very similar, with the canon having a larger maximum aperature, which is generally not important in a wide angle lens. The built construction is EX, they higher line of sigma, and it excellent. The focus motor is HSM, making it fast, and very accurate. Resolution chart show the sharpness to be very close to that of canon. The color and contrast is excellent, the flare and chromatic abberation genenrally well controlled. A fun lens to use, and excellent value. |
