Nikon F Photomic FTN "Apollo" + Nikkor-Q Auto 1:3.5 f=135mm + Nikkor-O Auto 1:3.5 f=35mm

Nikon F from Camerapedia

The Nikon F was introduced in 1959 with a comprehensive range of high quality lenses and accessories. During its lifespan, new items were continuously added, comprising bulk film magazine, electrical motor drive, viewfinders, focusing screens, close-up and scientific attachments, flash units, remote controls, and even a Polaroid back, the Speed Magny, as well as a wide variety of exposure meters, both separately available or as part of the finder prism, the latest of those being TTL meters, known as the Photomic.

It would be impossible to plan for every conceivable future attachment to go on the Nikon F, and although the designers have eminently well succeeded, quite a few less practical arrangements have been employed. Nippon Kogaku used their Nikon rangefinder camera as a starting point, adding a mirror housing and an interchangeable viewfinder, when developing the Nikon F body. The finder attachment resembles that employed for the Exakta Varex, using a number of catches. As it turned out, the system was not the best choice, and it has been the cause for several afterthoughts.

The most important attachment, however, is the lens. Nippon Kogaku developed a bayonet mount still found on their digital cameras. It is made of stainless steel and just sufficiently wide to accept all internal connections that have been added ever since its inception. The big challenge for every camera maker around 1960 was how to incorporate an exposure meter in their camera, and each came up with their own solution, some great, others less practical. None envisioned all the necessary interconnections, and a wide range of solutions were found. Connecting the meter to the shutter speed dial was obvious, but including the aperture ring was not so clear, most relied on manually transferring the meter reading to the lens aperture ring. The Nikon Selenium meter connects to the shutter speed dial, and the reading must be transferred manually. It is attached to the nameplate in front of the finder, surely looked upon as a temporary solution. In 1962, the Photomic CdS meter finder was introduced, with a circular external meter window. The meters were connected to the lens using an external fork on the aperture ring and a pin reaching down into it from the meter above. This system prevailed for decades and was sturdy, but rather clumsy and far from perfect. On the ensuing range of TTL finders, beginning in 1965, various improvements were introduced. The main problem was to calibrate the meter for the maximum aperture of the attached lens. This was at first accomplished manually, later on the Photomic Ftn, by twitching the aperture ring through its full range.

The Nikon F is extremely sturdy and reliable, and quite easily handled. The camera back, however, is not hinged and has to be set aside when changing film. Because the finder is detachable, the accessory shoe is at the side, requiring special attachments. A small window in front of the shutter speed dial shows the flash synchronisation setting, selectable by lifting the chrome collar surrounding the dial. In the middle of the shutter-speed dial is a small black dot a shutter wind indicator: at nine o'clock it is wound, and at seven o'clock it is run out. A film length reminder and an automatic reset frame-counter shares the space at the hub of the wind lever.

To remove the finder a stiff button at the camera back is depressed, possibly using a blunt object. To remove the focusing screen it has to be depressed again while the camera is held upside down to let it fall out on a soft lint free cloth. Replacing the plain prism finder or a waist level finder requires just depressing it onto the camera until the three latches catch. The Photomic finders rely on an additional mechanism grabbing around the Nikon nameplate. An additional handle at the right-hand front of these finders must be pushed simultaneously with the stiff one at the camera back. Removing and attaching the Photomic requires some practice to accomplish. Always double check that all the latches have engaged properly. When the finder is in place and a lens is attached, the meter must be set for the lens maximum aperture, aided by a scale on the meter prism front.

At the upper left-hand corner of the camera is the PC sync. contact, and lower down, close to the lens, is the lens release button. At the opposite side of the lens are a depth of field preview button and a mirror up knob. The mirror goes up when the shutter is released, and it stays up until the knob is returned to the index point. A small self-timer handle, with 4, 8, and 12 seconds index marks, is also at the right-hand front, doubling as a grip as on most SLR cameras.

The standard lens for the early Nikon F is the Nikkor-S Auto 1:2 f=5cm, half a year later the Nikkor-S Auto 1:1.4 f=5.8cm became available

Mine is the Apollo version.
