Reflex-Nikkor 2000mm f/11
This is the longest reaching and the largest dimension Nikkor optical lens for 35mm photography. It works almost like a optical telescope which projects a compelling 40X magnification of the subject when compared with a normal 50mm standard lens. The 1° 10' picture angle is another distinctive feature of the lens. This 2000mm catadioptric lense has a the same fixed f/11 maximum aperture like its 1000mm counterpart which contributes to its huge dimension (262mm dia. x 598mm long (overall) for light gathering power.
Prior to its availability, the longest reaching Reflex Nikkor was limiting to 1000mm (First introduced in June, 1959 in either S-mount for the rangefinder Nikon or F-mount for the Reflex Nikon F). A prototype of this lens was first displayed at Photokina in 1968 and actually production was only commenced in 1970. It was among a serious effort by Nikon to strengthen their position as the fore runner at the professional 35mm camera users' market and on the other hand, as a prelude to prepare the next major upgrade of their now legendary Nikon F professional 35mm SLR system with the Nikon F2 system debuted a year later in 1970/71.
In between the announcement and availability of this lens, between year 1969-1971 we saw Nikon aggressively introducing a series of interesting optic where some of the very original Nikkor lenses were being introduced in a sequential order. Some of the important Nikkor lenses which have stamped a landmark in the good course of development and widespread popularity of Nikkor lenses were actually being introduced during this period of time. For an example, the three distinctive circular fisheyes, Fisheye-Nikkor 6mm f/2.8 (world's widest 35mm optical photographic lens), Fisheye-Nikkor 8mm f/2.8, Fisheye-Nikkor OP 10mm f/5.6 (world's first 35mm optical photographic lens which used a Aspherical lens element), a redesigned compact ultra-wideangle Nikkor 20mm f/3.5, a high speed top quality wideangle Nikkor 35mm f/1.4 and a high speed medium telephoto lens, Nikkor 180mm f/2.8, an innovative pancake-sized flash coupled Nikkor 45mm f/2.8GN, a dedicated close focus Bellow-Nikkor 105mm f/4.0, the emergence of the legendary Zoom-Nikkor 80-200mm f/4.5 which changed everyone perception towards quality of zoom lenses and two Mirror lenses with fixed aperture in the popular Reflex-Nikkor 500mm f/8.0 along with the exotic Reflex-Nikkor 2000mm f/11 featured here.
This remarkable Mirror lens has a large front attachment size of approx. 254mm and weighs at an astonishing 17,500g ! An outstanding in its design was at its lens handling where simple operation via two built-in knobs one for focusing and the other for filter selection. The focusing is done via a knob at the side section that requires a few rotations to focus from its closest focusing distance at 18m (60ft) to infinity (Note: early version suggested it was done by means of the focusing knob at the side In three rotations, covers OO - 20m (OO - 60 ft). Combination peep sight and carrying handle is built into the top section of the lens barrel to facilitate mobility. The filter system was via a filter turret where a set of four supplied filters in L37c (older version was supplied with L39), Y48, O56 and R60 (ultraviolet, yellow, orange, and red) which requires to turn a knob to alter the choiced filter. Two built-in tripod sockets, plus an optional yoke mount, allow secure mounting on a tripod, clock drive, or other support. The lens mount rotates in click stops for both horizontal and vertical shooting where its Angle of Elevation: 60° Angle of Depression: 35° where Horizontal Turning: endless.
This rarely seen lens was believed to be hand made and on a special order basis. It was generally been seen finished in white colour which carries the purpose of minimizing thermal effect if use frequently in the field (but there was an early version first displayed at Photokina in 1970 which actually was equipped with industrial-gray color that came along with a dedicated rock steady AY-1 mount).
Although most people would regard this lens as a special purpose photographic lens as its strength in its extraordinary long focal length with 1°10' angle of view also means it can be very restrictive for general photographic application. Neither the lens is easy to carry along nor friendly to handle as its dimension and weight factor often require time consuming setup for shooting. The fixed aperture at f/11 is another area that demands extra-attention as only favorable lighting condition (or using high rated film speed types of film) will enable favorably fast shutter speed to be used to minimize chances of blurry images caused by magnification of movement during shooting. However, no doubt this lens still presents a good solution for those who wishes to go for truly frame-filling sports, wildlife, physically inaccessible events or objects and astrophotography pictures. Whatever it is, theoretically when combines the lens with a working 1.4Xor 2X Optical Teleconverter, this lens would be transformed into a 2880mm or a 4000mm ultra-super telephoto lense - that is indeed a temptation for any photographer to have a hand on for such a wild combination.

Some publication suggested it might bear with serial number began from 2002XX.

Use an Ai-S version for better compatibility, read the respective Tele-Extender(s) sections.
