NOKTON 21mm F1.4 Aspherical E-mount
Announcing the NOKTON 21mm F1.4 Aspherical E
A Super Wide-Angle lens for Sony E.
The NOKTON designation is only given to high-speed lenses in the
Voigtländer lineup with a maximum aperture of F1.5 or faster. When the
first NOKTON was released in the 1950s, it was positioned as a lens that
enabled images to be captured even in low light. However, with
constantly improving imaging sensor sensitivity, the advantage of a
high-speed lens nowadays is the ability to use as a means of
photographic expression the out-of-focus bokeh created by opening the
aperture.
The NOKTON 21mm F1.4 Aspherical E-mount is a large maximum
aperture manual focus lens optimized for the imaging sensors of Sony
mirrorless cameras. The 21mm focal length covers an angle of 91°
which is about 10° wider than a 24/25mm focal length to create a super
dynamic perspective. Generally, the wider a lens gets the deeper the
depth of focus of the lens, but with the NOKTON 21mm F1.4 Aspherical E-mount lens, the extremely
large maximum aperture for a super wide-angle lens enables imaging that utilizes “bokeh” (out-of-focus
blur). The minimum focusing distance of 25cm can be used to emphasize the thin depth of focus in the
close range. The lens utilizes a floating mechanism to maintain excellent imaging quality throughout the
focusing range from close distance to infinity. Furthermore, the lens features aspherical optics to
eliminate distortion and chromatic aberrations in addition to enabling a compact optical design despite
the large maximum aperture. The aperture ring has click stops in 1/3 steps. The lens also features a
click stop switching mechanism that enables the click stops to be turned off when shooting video. The
included petal Hood can be attached/removed easily for hassle-free filter work, and can be attached in
reverse for easy storage.
