Sigma 50-100mm f/1.8 art
Sigma produce a new lens which will be very interesting for many especially portrait photographers. Everybody waited for the Sigma 85mm f/1.4 Art and the lens which will come is the Sigma 50-100mm f/1.8 Art. It is an unprecedented lens. Earlier Sigma has a 50-150mm f/2.8 lens but this lens is brighter.
Sigma earlier made several big success which such interesting bright zoom lenses for example the Sigma 18-35mm f/1.8mm art. The 50-100mm is classical portrait range, which allows the photographer to frame the subject as he/she want.
Exotic lens elements: the lens has 4 interesting lens elements: 1 SLD and 3 FLD elements, it is quite interesting for such a lens, when the concurrence only throw 1 Ed elements maximum in their similar prime lenses.
The lens has totally 21 lens elements in 16 groups, which I would say a complex design.
Filter size is 82mm.
