Nikon presents its new AF-S Nikkor 105 mm f/1.4E ED, which will be the brightest 105 mm on the market today. With new optics, the AF-S Nikkor uses an electromagnetic diaphragm that has been advocated for in the world of optics for many years.
As we’ve mentioned, those in charge at Nikon have confirmed that the old – but by no means outdated – mechanical operation lever of the diaphragm of the Nikkor lenses, which is reminiscent of the sixties, does not only fail to offer the needed precision for the available means of exposure in the cameras of the 21st century, especially regarding burst shooting in sequence, but in addition, it also takes away the designers’ freedom when deciding on the optical scheme. This is because with this type of lever, the diaphragm must be located as close as possible to the mount to avoid issues with torsion of the lever. It then becomes a limitation when deciding upon the location of the lenses and their diameters.
It isn’t known if this freedom of design that offers the electromagnetic diaphragm has influenced the formulation of this very bright 105 mm, but everything suggests that this is so. The AF-S Nikkor 105 mm f/1.4E ED is not optically stabilized – very typical for high luminosity lenses – and as is natural, it covers the 24x36mm format of the high spectrum Nikon. Given its scarce – but welcome – field depth at full aperture, it is almost certain that it will offer micro-adjustment of the camera by the user, supported by implemented and barely announced automatic correction systems in the company’s latest DSLR’s.
The new AF-S Nikkor 105 mm f/1.4E ED possesses the optical scheme of 9 groups of 14 lenses, 3 of which are made of ED optical glass with low chromatic dispersion. The anti-reflective coatings are made from N-type nanocrystals, and are additionally protected by layers of fluorides and moisture/dirt repellants. All of this is mounted atop a body that is protected from the outdoors.
In terms of image performance, there is talk of a very special bokeh, suggesting that it will be similar to that of the AF-S Nikkor 58mm f / 1.4G, supported by a diaphragm of 9 blades that closes up to f/16. There is also speculation about a great playback of out of focus lights that is free of coma and flare, even in the edges and outer limits of the image. With respect to physical parameters, there is no more and no less than 985 grams for Ø 95 mm (Ø 82 mm filter) for a length of 106 mm. The minimum focusing distance is 1 meter, which is quite fair for this kind of lens.
When converted, the AF-S Nikkor 105 mm f/1.4E ED has an estimated price of about $2,199.95, and it has been announced that it will become available in late August. Here, Nikon does not only celebrate its 99th anniversary, but also the production of 100 million Nikkor lenses.
