Digital Camera Lens
18-50mm f/3.5-5.6 DC / HSM

Zoom lens that designed to suit the characteristics of digital cameras

Exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of most digital SLR cameras and this has resulted in a compact lightweight lens. The use of aspherical lenses provides correction for various aberrations and makes high quality images a reality throughout the entire zoom range. The Nikon fit version also includes an HSM auto focus motor.

Compact-Lightweight zoom lens
Compact-Lightweight zoom lens has a maximum diameter of 62mm overall length of 67.5mm and weight of only 250gr and filter size of 58mm. Compact dimensions offers superb handling and mobility. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance.

Exclusively designed to suit the characteristics of digital SLR cameras
We took digital characteristics into consideration when designing the lens power layout and created the most suitable lens that makes high quality images a reality throughout the entire zoom range. We used the most appropriate coating for digital products to cut down flare and ghost caused by digital SLR cameras and to produce the best color balance. It can be used with the supplied lens hood to block out extraneous light.

Very convenient lens design
18-50mm F3.5-5.6 DC zoom lens has a minimum focusing distance of 25cm (9.8in.) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5. The focus ring provides easy operation in manual mode. A distance scale on the focus ring is an easy to use and convenient addition.

Amateur Photographer - Lens Supplement 2006
‘The Sigma 18-50mm f/3.5-5.6 has a compact, lightweight design measuring 67.5mm long with an overall diameter of 62mm for a weight of 250g. The zoom movement is reasonably smooth and feels just right. Though the manual focus movement is free, it is not sloppy.’
   

Practical Photography - September 2006
‘Overall, the lens feels solid compared to the basic lenses that come supplied with the 350D or D50, while the close focusing distance is one of the best in this class. The levels of chromatic aberration are excellent compared to many of the other lenses in this test.' 'As the only third party lens available in this class, the Sigma 18-50mm offers a perfect solution for all users and beats the quality of many of the manufacturers' own lenses.'

 
Photography Monthly - November 2006
‘Packaged with lots of cameras, this lens is an improvement on many of the manufacturers ‘kit’ lenses. Centre resolution is good throughout the range, verging on outstanding between f/5.6 and f8.’
