Voigtländer Sony-E Nokton 1,0/50mm asph.

The NOKTON 50mm F1 Aspherical is an ultra-fast manual
focus standard lens exclusively for Sony E-mount cameras.
Covering a full-frame image circle, the lens is optimized for the
image sensors of Sony mirrorless cameras.
The lens captures the image made by the optics directly without
data filters.
The built-in distance encoder also makes the camera
compatible with models equipped with 5-axis in-body image
stabilization, which uses distance information to the subject for
shift stabilization. It is also possible to magnify the image in
the viewfinder by operating the focus ring for more accurate
focus.
By manufacturing an aspherical lens from a glass material with a high refractive index, we have created an
ultra-fast lens that is portable despite its ultra-fast F1 aperture.
In addition, by adopting a floating lens, a stable image quality can be obtained from the shortest shooting
distance of 0.45m to infinity.
Focusing is manual with a metal focus ring which has a diamond pattern for excellent and accurate focus
grip.
The aperture is controlled by a mechanical ring on the lens. The aperture ring has a click-switching
mechanism that allows the aperture to be used without clicks when shooting video. The aperture has 12
diaphragm blades, which allow the photographer to capture smooth out-of-focus areas and point light
sources as well in a well-defined form.
A metal lens hood is included.
