Digital camera reviews of Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR CamerasDigital camera Review: 10mm! Summary: 5 Stars
Shooting with a dslr is great in a lot of ways, but the sensor crop kills my wide-angle capability, which, to me, is absolutely awful!
Personally, I hate zoom lenses. I've got a full set of Nikon primes. And while I'd prefer a prime lens, these zoom lenses are the only game in town for wide angle on crop sensor dslr.
I like this lens because it goes WIDE on digital. I suggest you buy this lens for the 10mm and keep it at 10mm because the 10mm wide end is really where it's at and the reason to buy this lens over the alternatives.
For anybody considering 10mm vs 12mm at the wide end, unless you mostly use the narrower end of the focal length most of the time, 2mm is a SIGNIFICANT difference in field of view on short lenses. As the focal length increases (eg, from 400mm to 600mm), the difference in angle of view is not very large. But the difference between 10mm is 12mm even though "only 2mm" is no laughing matter, and if you don't believe me, you can do a comparison in a camera shop to prove it to yourself.
If you end up deciding to get a 12mm, you want to buy the sigma 12mm (I think it is 12-24mm?) because that lens covers full 35mm frame (and the angle of view has got to be absolutely amazing)!
Also, if Sigma or Nikon reads this review, please make an 8mm or 9mm f2.8 rectilinear crop sensor prime!
And if Sigma reads this review, I want some f1.2 or f1.0 AFD primes! 50mm for film maybe even a digital sensor version in some medium range focal length! I would definitely buy (full frame coverage of course) a mid length and a medium wide angle and a short tele! Neither Nikon nor Canon makes anything like that (well, canon kind of does/did), so you'd have the market segment dominated!
Summary of Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR CamerasSigma 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. Designed exclusively for Nikon digital SLR cameras capable of wide-angle photography, the Sigma 10-20mm f/4-5.6 lens is a powerful tool for landscape photography and other wide-angle applications. The lens offers an ultra-wide angle of view of 94.5 to 56.8 degrees, with three special low dispersion (SLD) glass elements and three aspherical lenses providing optimum image quality throughout the entire zoom range. The lens also incorporates a Hyper Sonic Motor (HSM) to ensure quiet, high-speed autofocusing in addition to full-time manual focusing. Other features include a close focusing distance of 9.4 inches, a non-rotating lens barrel that perfectly suits the petal-shaped lens hood (included), and a one-year warranty.
