Product Description

Product Description

The characteristics of digital SLR cameras were taken into consideration when designing the lens power layout. The new advanced lens design corrects various aberrations. This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras. This lens is specially coated to get the best color balance whilst cutting down flare and ghost caused by reflections from the digital image sensor and lens. It has excellent correction for vignetting and superior peripheral brightness is ensured. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations. The design produces a compact and lightweight, yet robust, construction with an overall length of 84.1mm (3.3in.) and maximum diameter of 74.1mm (2.9in.) and weight of 445g (15.6oz). This lens has a minimum focusing distance of 11 inches (28 cm.). It is equipped with inner focusing system. The non-rotating front lens element makes the lens suitable for using its petal-type lens hood and circular polarizing filters.

5.0 out of 5 stars A very good lens, October 5, 2006

By	RonAnnArbor (Ann Arbor, MI United States) - See all my reviews (TOP 500 REVIEWER)

I took a look a this lens almost as a fluke -- I wanted something that gave me quick speed at 2.8 but had more range than than the prime standard 50/1.8...and I was so pleased with the lens I have used it quite a bit more than I thought I would. The quality of the photos is excellent, good colors, good contrast. The lens is relatively light (less than a pound) so it "feels good" on the body. Compare this lens to the Tamron 17-50/2.8 They are virtually identical. This is a supurb replacement for your standard kit lens.

5.0 out of 5 stars Nice Lens!, June 8, 2006

By	Debra J. Brown - See all my reviews (REAL NAME)

I use this lens on my Nikon D70. It's great. Before I bought it, I thought I should get a lens with better range, example, the Nikon 18-200mm lens. My friend had told me about this one, so I decided to buy it for the heckuvit. I was glad I did. The range isn't a big deal now, but the only problem is--umm--uhh--I can't really think of any problems I've had with this lens, besides the fact that I all of my lenses, I use this one the most, and I paid all that money for the other lenses! Trust me, it's great.

5.0 out of 5 stars A very good lens indeed, April 1, 2007

By	A. Baker - See all my reviews (REAL NAME)

I bought this lens because my REAL Nikon film lenses did not perform well with my new digital SLR. To make the whole story short, I had invested $1400 in a digital SLR in hopes that I could use my Nikon lenses. But to my surprise...those lenses didn't perform well at all. So I took a chance on this Sigma lens (after reading the reviews of course). It was the least expensive lens in my bag but it gave the best result. The images were very sharp with good colors and detail. Again, thanks to those who took the time to write the earlier reviews. They had helped me tremendously.
