The Voigtlander 17.5mm f/0.95 Nokton for Micro Four Thirds is especially suited to video and film use. Its selective aperture control system allows continuous and soundless operation. A short minimum focus distance on 15cm and excellent bokeh due to the 10 aperture blades construction. Ultra-fast f/0.95 aperture not only lets in a huge amount of light, it also creates a very shallow depth of field, creating beautiful background blur.
