This lens is entirely mechanical so you have to focus manually. With a focal length of 17.5mm and an angle of view of 64.6° this aspherical lens allows extremely sharp images even at wide open aperture. Especially interesting for video- and film functions is the selective aperture control system, which allows a continuous and soundless change of the aperture and therefore the depth of field by simply switching over.
You change the aperture of the Voigtlander Nokton 17.5mm F0.95 levels via 2 rotary rings. With the first ring you adjust the aperture, with the 2nd ring you switch between your work and your maximum aperture diaphragm. This allows you to still be in lfocus in ow light.
The extremely short minimum focus (15cm) creates many possibilities and interesting perspectives for each photographer. Outstanding is the bokeh of the Nokton, created by the 10 aperture blades.
