The amount of interior lighting needed in environmental planning.Īpplication was on town planning especially on high-rise construction in urban planning.Ĭare must be taken to avoid narrow streets thus cutting the level of illumination,īoth inside and outside high-rise areas. The extent and transmission of heat radiation from a fire. In fire prevention, it can be used to make studies of Instance, it will help obtain the sky factor in evaluating the proper illumination With its orthographic projection formula, the OP Fisheye-Nikkor isĪ convenient tool for the betterment of civic environment. It covers a complete 180° hemisphere, producing a 20mm diameterĬircular image. Nikon can safely claimed producing the World's first 35mm lens with an aspherical Photo Aersenal can beĬontacted at Photo Arsenal Boris Jamchtchik, Altenfurter Str.16a 90475 Nuernberg Trading many used and new photo equipment of various labels.

Lens, it requires the mirror to be in the 'up' locked position before mounting.Īn accessory viewfinder, which can also be used on the 6mm f/5.6 Fisheye-Nikkor, Therefore, even with the use of narrow latitude colorįilm, uniform image brightness is obtained over the entire circular field. Of the same brightness are reproduced with equal density, no matter where they are Another characteristic of the OP design is that subjects Useful in advertising photography to emphasize the main subject by taking advantage To architectural design, civic improvement, street lighting, fire safety studies This proportion is called the 'configuration factor' or 'skyįactor' when the light source is the sky. Image area of the light source to the total area represents the luminance or brightness The light source is photographed with the OP Fisheye-Nikkor, the proportion of the This projection formula providesĪ special configuration through which the luminance of a place is measured. OP requirements, an aspherical front lens is employed. Periphery than the images produced by other Fisheye-Nikkors.

However, is larger in the center and gradually becomes more compressed toward the (OP) characteristics producing a circular image of 180 degree. This is a highly specialized lens that offers unique orthographic projection Originally introduced in 1968 and was discontinued eight years later in the mid
