Two Nikon patents have surfaced that present the corporate has designed two large-aperture zoom lenses presumably for its mirrorless Z-mount digital camera system: a 35-50mm f/1.2 and a 50-70mm f/1.2.
Initially discovered by Asibonet (which was noticed by Mirrorless Rumors), the 2 patents describe a variable zoom lens system that’s able to sustaining a wide-open f/1.2 zoom over the total vary and collectively would offer a photographer the flexibility to shoot between 35mm and 70mm with unbelievable light-gathering functionality and low depth of area. Nikon currently manufactures 25 Z-mount lenses of which just one is an f/1.2: the Nikkor 50mm f/1.2 prime lens. This isn’t the quickest lens the corporate has made for the system, as Nikon in fact additionally has the 58mm f/0.95 Noct as effectively.
The inner optics which might be proven as a part of the patent utility look giant and complex, which is sensible. In an effort to keep that extensive aperture by way of a zoom vary, these lenses will very seemingly be giant, heavy, and costly because of this. The 35-50mm f/1.2 patent describes a lens that’s as giant as 210mm, or about 8.3 inches. The width of the entrance factor isn’t proven, however it should very seemingly be fairly giant.
A large-open aperture of f/1.2 is already unusual in prime lenses, but it surely’s just about remarkable in relation to zooms. Sigma made waves in 2015 when it launched the 24-35mm f/2 lens since that already felt like three prime lenses in a single, however Nikon seems to be as if it plans to prime even that distinctive effort by making a sooner zoom lens — and doing it twice.
Panasonic and Leica have labored collectively to make two very spectacular f/1.7 zoom lenses within the 10-25mm f/1.7 and the 25-50mm f/1.7, however each of these optics are for the Micro 4 Thirds system which suggests the businesses might compress the dimensions of the optics required for a sensor that small. Primarily based on Nikon’s patent, it’s anticipated that its two f/1.2 lenses could be at the very least for APS-C if not for full-frame, which each would require a lot bigger parts not solely as a result of Nikon’s lenses could be sooner but in addition as a result of the sensor sizes they would want to work with are bigger.
Whereas these patents are thrilling, they don’t essentially imply Nikon will act on the designs. Rather a lot can go unsuitable between the patent and manufacturing stage, and Nikon might discover that these lenses are both too sophisticated or too expensive to make at scale. To place these doable issues into perspective, in 2012 Leica designed a 28-75mm f/3.5-5.6 lens that proved too tough to fabricate as a result of complexities of the mechanical and optical design, and the corporate canceled the challenge in 2015. One of many three examples of this lens that Leica ever made sold for $290,000 in December of 2020.
Nonetheless, if Nikon does handle to beat any points, these lenses would seemingly be thought of a few of the most spectacular zooms ever made.
