The lens is developed on Sigma’s Art line concept “pursuit of ultimate image quality”. The letters DG in the lens’ nomenclature denotes that the lens is designed for full-frame sensor camera bodies while the letters DN denotes that the lens is optimised for Mirrorless cameras. The lens under review is for the Sony E-Mount system. Let’s see how this lens performs on our test bench.
Design & Build Quality
The lens is designed for Sony mirrorless interchangeable lens cameras. The visual feel of the lens and its all-black construction is a delight to see and hold. The lens feels solid (as all Sigma Art lenses do). The lens mount is made of brass and plaited. A rubberised ring at the lens mount prevents dust/ water splashes from getting into the lens. The lens is dust and splash-proof (this does not mean that it can be used continuously in rain). Besides this, the front surface of the lens is coated with a special water & oil repellent coat that can prevent (to some extent) smudges and finger-prints from adversely effecting the image quality. Filter diameter is 82 mm. The lens is made in Sigma factory in Japan and weighs 1090 g.
