After much speculation, Sony has announced a 35 mm f/1.8 lens under its FE series. The lens incorporates 11 elements, one being aspherical to suppress aberrations and maintain image resolution into the corners of a shot. The SEL35F18F weighs just 280 g (9.9 oz) too. The FE 35 mm f/1.8 (SEL35F18F) will be available to order in August for US$750 (£630).
