Sigma 18-35mm f/1.8 DC HSM Art

Pros: Sharpness, color rendering, and performance against the solid construction

Cons: Weight, autofocus inconsistent at distances greater than one meter, suffers much refractive already above the diaphragms 5.6

Opinion: A good lens in the aspect of sharpness and color rendering, but unfortunately these problems that I think make the most inutilizzabile.Dopo various tests and calibrations with dock sigma inconsistency has remained and I do not think it's a problem because of my D7100 with the Nikon 85 f1.8 not by any problema.A full aperture does not suffer at all of the purple fringe that is good for a perspective of this apertura.Veniamo the sore point, the effects of refraction that would normally come into play in very closed diaphragms, are visible even above 5.6, and this makes it a lens completely unsuited to the landscapes where it is required a greater depth of field
