Product Description

10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography Wide angle of view (102.4� at 10mm and 63.8° at 20mm) offers the photographer greater freedom of expression. These are special DC Series Lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus! Three SLD glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration. This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm (9.4") at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently. Please note: Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.

Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Sigma Digital SLR Cameras Review

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 "test" images are blown up to 16"x20" size. I never notice any lack of sharpness in "real" pictures. I care more about color saturation, contrast and color balance anyway. In this area, the Sigma does well. Saturation and contrast are equal to both my other Nikon lens - particularly at f8 and smaller aperatures. Wide open, I find some weakening in contrast. The Sigma has a warmer color termperature than my other lens. One click toward blue in Photoshop would fix this minor variance in color. But I use my 10-20mm almost exclusively for landscapes. The warmer color is generally a good thing.

I have noticed some vignetting @ 10mm f4. Zooming to 12mm or stopping down to f5.6 elminates any artifacts in pictures I have taken thus far. I have found it's more important to avoid "thick framed" filters - and stacking filters is a no no with this lens. They cause more darkening than a wide open f-stop. BTW: I added a 72 to 77mm step-up ring to my 18-200m VR Nikon to allow me to share filters between my zoom lens.

I do miss having a manual/autofocus switch on the Sigma lens. I have accidently nudged the manual focus ring a couple of times. With that said, the incredible depth of field of this lens (or any lens at this focal length) means small focusing errors can be tolerated :)

I recommend this lens - even to people like me, who never had a non-nikon lens before.
