By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM, this lens achieves a compact size and a minimum focusing distance of 35cm. New material, Thermally Stable Composite (TSC) maintains its structure and has little contractility especially in varying temperatures, is incorporated into the lens barrel. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.
A wide range of photography is possible in one lens
Covering wide angle 18mm to telephoto 250mm, this versatile lens designed exclusively for digital SLR cameras, is suitable for all-purpose photography including landscape, sport, and macro photography. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.
Excellent for macro photography
Close-up capability is improved with the minimum focusing distance of 35cm throughout the entire zoom range, and maximum magnification ratio of 1:2.9. In APS-C size equivalent, macro photography with approximately 1:2 magnification ratio is possible. In addition, with this lens, the size and framing of subjects can be adjusted by rotating a zoom ring, making macro photography easier than using fixed focal macro lens. For further convenience, the maximum magnification ratio at each focusing distance appearson the side of the lens barrel.
Revolutionizing the design foundation results in compact size
Optimization of the power arrangement by such as incorporating double-sided aspherical lenses, and reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately 13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 73.5mm x Length 88.6mm. It ensures portability and overall ease of use, making it perfect for travel and leisure photography.
TSC (Thermally Stable Composite) Material
The material "TSC (Thermally Stable Composite)?, which has little contractility especially in temperature changes, as well as maintaining firmness, is incorporated into the lens barrel. Compared to Polycarbonate which is generally used, TSC has higher elasticity by approximately 25%. Since thermal shrinkage is low, it has high affinity to metal parts which contributes to high quality product manufacturing. It also contributes to the parts such as the zoom ring and scaling to be slimmer.
Brass made bayonet mount
This lens incorporates brass made bayonet mount which has both high accuracy and solidity, same as the mount for camera body. The special treatment to reinforce the strength is applied on the surface to make it a high quality lens that is resistant for long-term use.
Optical Stabilizer (OS)
Sigma's own unique Optical Stabilizer (OS) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate camera shake even in macro range photography where a small blur can be easily identified. When photographing a moving subject such as motor sport, it automatically detects camera move, and offers effective correction for camera shake.
Superior optical performance
SLD (Special Low Dispersion) glass element offers excellent correction of color aberration. Three aspherical lenses including double-sided aspherical lens together with the latest design, prevent and correct all types of aberrations including astigmatism, achieving high quality images throughout the entire zoom range.
Flare and ghosting conscious design blades
From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions. Supplied petal-type hood can be attached to block out extraneous light which has a harmful influence on rendering of the lens, and prevent internal reflections to occur.
Warranty - 1 year America Warranty + 3 year USA extended warranty on manufacturing and workmanship for a total of 4 years of coverage from date of purchase.

Great Lens, Great Price
from Cape Girardeau, MO
Very simple:- I dropped my old lens and was sad.- I found this lens at a very good price at buydig.com and was happy.- I started using the new lens I purchased at buydig.com and was so very happy! So happy, in fact, that I was glad that I dropped and broke the first lens in the first place!
Bottom Line Yes, I would recommend this to a friend

I love it!
good all around lens
from Bryant, Ar
The Sigma 18-250mm macro zoom lens is a fine lens and a good value. The long zoom range make this an ideal all around lens that will rarely come off my camera.
from Carmel, CA
I will be taking this on all my overseas trips as it is compact and will be able to get a wide variety of shots. I have found the images are as good or better than my more expensive Canon 70-300 lens. I considered the equivalent Tamron (made in China) but the trusted photo review sites gave the Sigma (made in Japan) a better review and they were right.
Good all around lens
from Kennewick, WA
General uses inside and outside. Scenery and people, portraits, etc. Only reason I gave it 4 and not 5 stars is the need to switch off Auto focus, in order to manual focus, unlike Canon USM lenses. Also it stops down to 5.6 sooner than Canon's 18-135.
