A Close Look at the Rare Vintage Nikon 1000mm f/6.3 Mirror Lens

We often get rare and unique equipment through our doors at KEH Camera; the kind of gear that many photographers often dream of seeing. One prime example of those unique pieces is this 1000mm f/6.3 Reflex lens from Nikon, circa 1959. The latest in our Legacy Lens video series sees this F-mount catadioptric telephoto adapted onto the front of a Sony Alpha 7S III to see how it performs in 4K.

This video series highlights the optics and design of vintage manual lenses on modern-day mirrorless sensors, an affordable and fun way to add some unique characteristics to your photos and videos. Often popular with budding cinematographers, this method usually produces a video look that's more organic than you'd get from razor-sharp modern lenses, with the combined benefit of smooth manual focus and physical aperture ring operation.

With a somewhat mysterious past, information on this 1000mm lens proved difficult to find. Even directly contacting Nikon was less fruitful than expected. Analysis of the available serial number records shows that this particular sample was created around the middle of perhaps only 60 units ever produced for the F-mount. Take into account that the lens was produced over 60 years ago and the piece starts to feel a bit less like a lens and a bit more like something that belongs in a museum.

The compression and reach shown in the test footage is stunning, but the engineering of the lens itself is deeply inspired. Considering that this lens was the first mirrored telephoto produced by Nikon, the addition of two rotating dials that feature eight different lens filters is a great example of the technical prowess that sticks with the brand even now.

A series of ND filters to simulate different f-stops is a brilliant addition to this type of fixed-aperture catadioptric lens, and the inclusion of yellow, orange and red contrast filters gives the shooter more control over their image when shooting in black and white.

Focus is achieved through a smooth, rail-based bellows mechanism on the rear of the lens. To protect this moving element from damage, a helmet-sized metal bowl latches onto the lens for transport or storage. An enormous reversible lens hood also protects the front elements from bumps, although flare and contrast loss can prove to be an issue when shooting toward the sun. Anti-reflective lens coatings have come a long way in the last 60 years.

Cosina Launches Voigtlander APO-Skopar 90mm f/2.8 for Nikon F-Mount

Cosina has launched the Voigtlander APO-Skopar 90mm f/2.8 for Nikon's DSLR F-mount. Cosina says that the lens has been designed to bring the appearance of chromatic aberration to as close to zero as possible.

The APO-Skopar 90mm f/2.8 follows the Color-Skopar 28mm f/2.8 SL II S that Cosina launched in September, also for F-mount. It, like the 28mm, is a tribute to classic SLR lenses. The 90mm f/2.8, in particular, is described as a tribute to the lenses produced between 1965 and 1974 and features a silver rim (which Cosina is nicknamed Sakijiro among colelctors) or a black one (called Sakiguro). Both color options will be available when the lens comes to market.

The company says that the newly designed optical system uses "anomalous partially dispersed glass" in five out of the seven elements that are arranged in the seven-group construction. It has a 27.5-degree angle of view, a maximum magnification of 1:8.1, a nine-bladed aperture diaphragm, and a 52mm front element filter size. The lens features an aperture range of f/2.8 through f/22.

Cosina says that it uses an apochromat design that "makes the on-axis chromatic aberration of RGB, which constitutes the three primary colors of light, as close to zero as possible."

Cosina adopted an all-metal helicoid unit that it processed and adjusted with what it describes as high precision and high-quality grease that produces appropriate torque and allows for smooth as well as precise and delicate focusing operation. Given that the lens is entirely manual focus, this kind of attention to detail in the focusing is likely to be appreciated. The company described similar attention to detail in its 28mm f/2.8.

Also like the 28mm f/2.8, the APO-Skopar 90mm f/2.8 is compatible with a variety of Nikon bodies, including Nikon's that feature Ai-S with built-in CPU, but it also has an Ai coupler that Cosina says makes it possible to use with a variety of cameras from classic SLRs from the era the lens celebrates through the latest DSLRs.

The lens is designed specifically to be compact, and Cosina says that despite its high performance, the lens is just 40mm long.

Cosina says that the Voigtlander APO-Skopar 90mm f/2.8 will be available in November in both black and silver iterations for 68,000 yen, or about $596.

Nikon Has Discontinued Several F-Mount Lenses: Report

It appears that Nikon is beginning to discontinue its F-mount lenses. Seven lenses are now appearing as "old product" on Nikon's official website, which is a term used to describe products that have been officially discontinued.

As originally reported by by Asobinet and noted by Nikon Rumors, Nikon has listed a total of seven F-mount lenses as "old product," six of which are new at the time of publication. Nikon Rumors reported that it had retired the AF-P DX NIKKOR 18-55mm f/3.5-5.6G VR lens on May 9.

The six additional F-mount lenses that now appear to be discontinued are the AF-S Nikkor 16-35mm f/4G ED VR, AF-S Nikkor 28-300mm f/3.5-5.6G ED VR, AF-S Nikkor 200mm f/2G ED VR II, AF-S DX Nikkor 16-80mm f/2.8-4E ED VR, AF-S DX Nikkor 18-300mm f/3.5-6.3G ED VR, and AF-S DX Micro Nikkor 85mm f/3.5G ED VR.

All seven lenses are listed as out of stock with major U.S.-distributors and given all of the above have the designation as "old product" on Nikon's official website, it is unlikely that store shelves will see their stock replenished again.

Nikon did not immediately respond to the request for comment.

The discontinuation of these lenses follows a report from earlier this week that Nikon was phasing out its APS-C line of cameras. While at the time, only the 18-55mm f/3.5-5.6 lens is officially noted as discontinued, reports that some of the cameras -- such as the D500 -- had been listed as out of stock for months led some to question the future of Nikon's support for its DX-format DSLRs.

Over the past couple of months, Canon also has discontinued a host of lenses as part of a "series optimization." At the time of publication, the company had ceased production on at least 22 EF lenses with more expected to come before the year's end.

As both Canon and Nikon focus efforts on mirrorless cameras and lenses, ceasing production of older DSLR lenses is to be expected. Specifically in Nikon's case, the company likely needs to put its entire effort behind producing Z7 II and Z6 II cameras, as it has had difficulty meeting the demand for the new devices.

Last December, Nikon announced that it would be shuttering its domestic Japanese camera production for good and moving it to Taiwan as part of a company-wide initiative to reduce operating costs by 59%.
