Flenda went on sale in February NOKTON 50mm F1.0 Aspherical Z-Mount maximum aperture grinding aspheric lens

CTOnews.com, February 6, 2008. Flenda will launch a new Voigtlander Nokton 50mm F1.0 Aspherical Z-Mount ground aspheric lens with a maximum aperture in February 2023, a full-frame mirrorless camera for Nikon Z ports, and optimized for Z system image sensors. Now the specific specifications have been announced. It was previously announced that the price of the NOKTON 50mm f / 1 aspheric lens (Nikon Z bayonet) is 264000 yen (currently about 13702 yuan).

Nokton 50mm F1.0 Aspherical uses 7 groups of 9 lenses, while the first aspheric lens of the lens uses the latest grinding technology GA (Grinding Aspherical) to grind extremely precise aspheric lenses. Even if the lens is shot with a full F1.0 aperture, it can effectively reduce the dispersion of the purple edge and show a soft astigmatism. The length of the lens is only 66.6mm, the weight is only 598g, the viewing angle is 47.9 °, and the circular aperture is composed of 12 aperture leaves. The recent focus is 0.45m. Behind the mirror is equipped with Exif electronic information to cooperate with the 3-axis shockproof of the fuselage, and there are three new auxiliary focusing functions: (1) focus color change focus, (2) peak focus function and (3) image magnification focus.

1 grinding aspheric lens + 1 double-sided aspheric lens

CTOnews.com learned that the Flenda Nokton 50mm F1.0 Aspherical uses seven groups of nine ultra-high-definition lenses, and the factory needs to solve the problem of expanding the lens aperture to F1.0. The difficulty is to turn high-refractive glass materials into high-definition aspheric lenses.

Usually, aspheric lenses of ordinary lenses are made by module pressing. Flenda's designers know that aspheric lenses are not as simple as concave and convex spherical lenses, and their curves vary from center to edge. Flenda uses the latest grinding technology GA (Grinding Aspherical) to slowly grind ultra-high-definition aspheric lenses, of course, with the moving position of the lens group when focusing, to get the best image from the closest shot to infinity. The advantage of full-open F1.0 aperture shooting is that it can easily capture a clear image by hand in a dim light environment.
