A short sigma lenses review and comparison with Nikon will show that sigma lenses produces top-class lenses.In order to categorize the best Nikon and Sigma pro camera lenses for your photographic needs, first let’s take a look at some of the nomenclature used in the lenses.
Pro camera lenses always desired by specialized photographers, usually due to reasons such as improved optical quality, superior build and better overall presentation. Each lens manufacturer has his own system of nomenclature. Sigma EX Lenses, Canon L lenses and Nikon G lenses indicate superior build and optical quality and are used to distinguish them as pro lenses.
A normal & usual lens is one with the similar range of vision as the human eye. It is comparable to a 50mm lens for a 35mm (full format) camera. On a slighter sensor camera, the equivalent lens is a 30mm which is existing in Sigma, but is not manufactured by Nikon. This makes the Sigma 30mm f/1.4 EX DC (sigma slr lenses) a very good buys.
Wide to Telephoto Zoom (18-55mm/18-50mm) are generally complete as Kit lenses and have one main fault, and very small space (e.g. f/4 or f/5.6) which makes it problematic to shoot in low light deprived of a tripod. The pro lenses from both Sigma and Nikon are f/2.8 which resolves this problem. The Sigma 18-50mm F2.8 EX DC is in peacefully priced, why not to use sigma lenses for canon and nikon?
The macro lenses from Nikon and Sigma are available both as prime lenses with shorter focal lengths and as telephoto lenses with longer focal lengths, when it comes to the longer focal lengths, the Sigma lenses offer extremely good quality for their price point.
