300mm f/4.5 ED Nikkor (non-Ai)

The 300mm f/4.5 ED-Nikkor lens was introduced in 1975, although externally almost identical to its non-ED sister model, offers a substantial improvement in optical performance for those demanding the best in telephoto photography. The 300mm f/4.5 ED Nikkor was among few other exotic class lenses, namely 600mm f/5.6 ED, 800mm f/8.0 ED and 1200mm f/11ED being the first batch of Nikkor lenses that utilized ED glass for correction of chromatic aberration, all the lenses did not a Internal focus design.

Featuring Nippon Kogaku's method of developed "Extra low Dispersion (ED) glass" for some of the lens elements to achieve a high level of chromatic aberration correction. The unique characteristics of this glass and the manner in which it is incorporated in this lens enable approximately 90% reduction of the secondary spectrum over the full 400 to 1000rum wavelength range; as a result, images are needle sharp and full contrast at all apertures, including full aperture.

One added benefit with this lens is the excellent performance for infrared photography; with this model, infrared focus is identical to visual focus, thus eliminating the requirement for corrective refocusing as with other lens. Other lens features (e.g.,, the use of NIC on lens surfaces, the fully rotatable tripod mounting collar, etc.) are identical to those offered on the standard Nikkor 300mm f/4.5 lens; thus equipped, this lens offers the fullest ease of operation for the photographer.

The optical formula for this ED version was a 6 elements in 4 groups design but the aperture only stopped down to f/22. Serial number for this lens could have been started from 173101. This lens has a equivalent AI version when Nikon introduced the lens coupling system in 1977, for easy identification, those series of AI Nikkor 300mm f/4.5 ED could have been started from a serial number of 190001. Eventually, this lens was replaced with an updated version featuring an Internal Focus design, Nikkor 300mm f/4.5 ED-IF in 1978.

300mm f/4.5 Nikkor (non-AI)

In March, 1975 the 300mm f/4.5 Nikkor has another cosmetic upgrade where all matte finish is provided. The lens has a five rows of rectangular hard rubberized type of focusing ring design. It provides the high image magnification and age of hand held opera tion that make for top-quality results under de planning shooting situations requiring substantial separation of the photographer and the subject situations such as sports, wildlife and action photography. Improvements in design have been inter porated into this new model to provide for greater ease of operation, while at the same time maintaining the high optical standards of its predecessor, the 300mm Nikkor-H Auto.

A fully rotatable tripod mounting collar design was first used (with locking screw) that makes for easier changes from horizontal to vertical format shooting. Also, the new focusing and aperture rings provide for improved gripping, resulting in greater ease of focusing and aperture selection. And, of course, the application of NIC on air-m-glass lens surfaces keeps flare and ghost under full control, while contributing to im p roved cc I a r ren d it in n. Oth at f eat u Res, Sit ch as t he slip-out lens hood, automatic diaphragm, meter coupling prong and capability for compensation of focus shift dup to thermal changes, make for excellent usability. Close focus is4m (13ft)

Similarly, this lens went through the AI conversion in 1977 and those series could have a serial number began from 510001.
