Leica predstavila najhitrejši objektiv na svetu

Prestižni nemški proizvajalec fotoaparatov in objektivov je objavil, da je izdelal najhitrejši objektiv na svetu. Hitrost pri objektivih se meri s podatkom, koliko svetlobe so sposobni prepuščati, kar je pri Leicinem objektivu Noctilux označeno z vrednostjo zaslonke F0.95. To pomeni, da prepušča 11 odstotkov več svetlobe kot njegov predhodnik F1.0. Običajna vrednost pri povprečnem objektivu je F3.5, kar pomeni, da prepušča samo sedem odstotkov svetlobe novega Noctiluxa. Leica Noctilux 50 mm/F0.95 bo na voljo decembra, cena pa naj bi bila okoli 10.000 dolarjev. (aNET)


The new LEICA NOCTILUX-M 50 mm f/0.95 ASPH. launched by Leica Camera AG, Solms, represents a milestone in lens design. It is the successor of the famous NOCTILUX-M 50 mm f/1 marketed by Leica for over 30 years, beginning in1975. Due to state-of-the-art optical and mechanical technology, Leica has now been able to make substantial improvements to the predecessor product. It is now possible to "break the optical sound barrier" of a lens speed of 1:1.

The LEICA NOCTILUX-M 50 mm f/0.95 ASPH. offers a unique performance spectrum: A noticeably higher lens speed has been achieved without any major alterations to the size of the lens. The characteristic rendering of the previous 50 mm f/1, valued by many users as a means of creative photography, has been retained with extremely shallow depth of field at full aperture. However, when stopped down, the lens performs comparably with the LEICA SUMMILUX-M 50 mm f/1.4 ASPH. launched in 2004 which was regarded as the best standard lens ever produced. On top of this, the vignetting and distortion values have again been improved on the predecessor model.

"The LEICA NOCTILUX-M 50 mm f/0.95 ASPH. is not only a unique high-performance lens in the M system, it also combines extremely high speed with imaging performance that can easily bear comparison with the other top lenses currently on the market. It is made of high-quality materials and intricately assembled by hand at the Solms factory to give a particularly reliable product that will retain its value for decades. The combination of state-of-the-art technology and meticulous craftsmanship based on skill and experience ensure the constant quality of every single Leica lens, once again widening the creative potential of Leica M photography", says Stefan Daniel, Product Manager for the Leica M system at Leica Camera AG.

The new LEICA NOCTILUX-M 50 mm f/0.95 ASPH. can be used for a particularly wide range of applications. At full aperture the lens features an extremely shallow depth of field, allowing incomparably esthetic portraits or detail studies, for example. The lens is also useful for available light photography, even surpassing the speed of the human eye. In normal light, it can be unhesitatingly used as a universal lens, and the extremely natural effect of the 50 mm focal length enables a true-to-life rendition of the subject.

The LEICA NOCTILUX-M 50 mm f/0.95 ASPH. integrates eight elements arranged in a double Gauss design symmetrical to the aperture. To ensure high imaging performance, two aspherical lens surfaces are used, which, due to their size and shape,  are manufactured in a complex grinding and polishing process at the Solms factory. Five of the glass elements exhibit partial anomalous dispersion, three of them are extremely highly refractive and therefore exceptionally expensive (the price per kilogram of this glass is roughly twice that of silver). An outstanding performance in the close-focus range is also guaranteed by a floating element, the last lens group of which changes its relative position to the rest of the system during focusing. Despite its higher speed and imaging performance, the LEICA NOCTILUX-M 50 mm f/0.95 ASPH. is still equipped with an E60 filter thread and a telescopic lock-on lens hood. Like the new SUMMILUX-M 21 mm and 24 mm f/1.4 ASPH. lenses, the new NOCTILUX-M 50 mm f/0.95 ASPH. has to be manufactured to extremely narrow tolerances, and new methods for centering and adjusting the lens elements were developed for this purpose.

no, ni ravno najhitrejši, je jih bilo že kr nekaj narjenih pr tej blendi in celo bolj odprti (mislim, da je je recimo en nikkor z 0.75 blendo ipd), ampak pustimo to. trenutno je hit.

Rodenstock TV-Heliogon 42mm f/0.75, pa se en Rodenstock je, ki je tudi f/0.75 pri 50mm. Pol je se Kowa 62mm f/0.75 in se en zeiss, ki se mi zdi, da je f/0.70 (samo 10 narejenih pa se tisti se mi zdi, da za NASO).

Tako, da ni glih najhitrejsi .

evo, pa se malo eksotike:

Photography’s “Night Owl” N-Mirotar Night Telephoto lens

A unique 210 mm telephoto lens for night photography. The N-Mirotar has the capacity to transform subjects invisible to the naked eye in near-pitch darkness into bright illuminated daylight-type scenes. Using only general-purpose black and white films, the image amplifier tube of the N-Mirotar intensifies residual light of the scenes 80,000 times and passes it on to the macro lens which delivers illumination to the film plane at 2,500 times the intensity of an f/1.4 lens. The effective lens speed is f/0.03. The N-Mirotar features a special grip for easy handheld shooting and operates up to 40 hrs. on two 1.5V penlight batteries.
