Proteus 4.0/80 mm Art Lens
Beautiful bokeh and a shallow depth of field with an amazingly smooth texture, what’s not to love about Proteus? With a largest aperture of f/4 and a focusing distance of 0.8 m, Proteus’ handcrafted multi-coated glass optics are ideal for portraits and detailed macro shots.
