With its fast f2 maximum aperture and distinctive 105-degree angle of view, this lens excels in low-light conditions and delivers immersive compositions for landscape, architecture, astrophotography and environmental portrait work. The optical formula features two aspherical elements and two high-index elements to minimise distortion and chromatic aberrations, whilst the all-metal construction and eight-blade diaphragm ensure durability and create an attractive starburst effect in night scenes. At approximately 340 grams and with a compact 63mm length, this portable lens is ideal for photographers seeking premium wide-angle optics at an accessible price point.
