Me and my Camera Lens Sigma

I have a Sigma 18-50mm f2.8 EX DC Macro HSM I just bought last week and honestly tell anyone I liked. I primarily used this lens of the camera as a standard zoom for my Nikon D40 because it covers all focal lengths typically used for indoor shooting. Also provides greater openness available for DSLR zoom, which is an absolute necessity for shallower depth of field for portraiture and low light.

So before enter into any deeper I have to explain first what is the full feature and advantages of my new lens Sigma House.

Sigma 18-50mm f2.8 EX DC Macro HSM has a large aperture zoom lens designed specially for use with Digital Slr cameras with the minimum focusing distance of 20cm (7.9 "). The lens is specially designed to suit the characteristics of digital Slr Cameras and provides a high level of optical performance. It has a large aperture of f2.8 throughout the entire zoom range, offers superior peripheral brightness and a compact, lightweight design. Also with a maximum magnification of 1:3 making it ideal for close-up photography.

What are the characteristics of this lens gives the camera?

Excellent Design optical

Sigma Camera lens produces an exceptional level of optical performance with a special low dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide excellent correction of color aberrations.

Compact and lightweight lens

The design incorporates both glass mold and hybrid aspherical lens technology which makes a compact and lightweight.

Reduction of ghosting and flare

The super multi-layer lens coating reduces flare and ghost. High image quality is assured throughout the entire zoom range.

Internal Focusing

An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-Shaped Lens Hood (supplied) plus circular polarizing filters.

Satisfactory to have my own opinion of this lens of the camera, with my camera lens sigma lenses compared with other of the camera, I prefer this because it provides quality and affordability.
