FEATURED REVIEWS
Sigma EX IS EXCELLENT LENSE!
I am a wedding photographer who recommended this lense to a friend who loves this lense as I do. It is the perfect all around lense. I am using it with my D-200! The gentleman from Canada should exchange it for a new one or check his camera body.
Large aperture standard zoom lens designed specially for use with digital SLR cameras.
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.
It is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor.
