You set focus by operating a big and comfortable ring - its full turn amounts to 200 degrees (as much as 70 degrees less than in the case of the Nokton 0.95/25). Combined with a magnified image in the LCD viewfinder it allows you to set the focus in a precise way. There is one snag, though – in the case of system lenses working in the MF mode one touch of the ring and the image is magnified automatically and a body with a Voigtlander „doesn’t know” that you move the ring so you have to blow up the image on your own.

Because of excellent f/0.95 aperture fastness the depth of field, provided by this lens, is not large. At the maximum relative aperture and for objects in the distance of 2-3 metres it amounts to about 50-70 centimeters. A depth of field scale on the body of the lens helps you when it comes to values by higher apertures.
