Compare Camera Lenses Quality
I have a Sigma 18-50mm f2.8 EX DC Macro HSM I just bought last week and telling anyone, honestly I really enjoyed it. I mainly used the camera lens as a standard zoom for my Nikon D40, because it covers all the focal lengths I usually use for shooting interiors. It also provides fast opening available for DSLR zooms, which is an absolute necessity for the shallow depth of field-portraits and low light photography.
Then, before entering any more to explain first what is the full functionality and benefits of my new camera lens Sigma.
Sigma 18-50mm f2.8 EX DC Macro HSM has a large aperture zoom lens designed especially for use with digital SLR cameras with focal length of 20cm (7.9 "). The lens is specially designed to meet the requirements digital SLR cameras and provides a high level of optical performance. He has a large aperture of F2.8 throughout the zoom range, offers superior peripheral brightness as well a compact and lightweight construction. Also having a maximum magnification of 1:3, ideal for close-up photography.
What are the characteristics of this camera lens provide?
Excellent optical design
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
The design incorporates both glass-mold technology, and hybrid aspherical lens that makes a compact and lightweight construction.
Reduces ghosting and flare
The Super Multi-layer lens coating reduces flare and ghosting. High image quality is guaranteed throughout the entire zoom range.
Inner Focus System
System Internal Focusing eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus polarizing filters circular.
Having my own opinion satisfactory for this lens, and my sigma lens compared to other camera lens, I prefer this one as it offers a quality and accessibility.
