Nikon Lens Serial No Serial Numbers You Might
Just have a look at your Nikon lens and scan the surface.Re: Purchase Verification. They do not have a standard location, but they are fairly easy to find. Serial numbers can be found in different places on your lens. Now that you have some understanding about serial numbers you might be curious about how to check Nikon lens serial numbers on your own Nikon lens.
Nikon Lens Serial No Full Serial Number
Got this lens.Find Nikon Lens Serial Number 2 Since the US D7100 number comes after the initial number for the much smaller Japanese market, it makes some sense to steal some of the Japan numbers. BR3 is too large no focus. The rear element is too long w/o some adapter. Its a visual guide, with photos of each mount type with a short description of what kind of lens mount it is below the image.In this Tale Eleven, I introduce a large-aperture, super telephoto lens NIKKOR-H 300mm f/2.8 made exclusively for news photographers that general photographers seldom have chance to see.Got any ideas for mounting a 10mm 180 OP super wide to a Nikon DSLR.

Particularly, it had been devoting to develop glass materials that have extra dispersion characteristics.However, to our regret, the production of ED glass was not in time for Nikon's first "3, 2-8". Nippon Kogaku, then, was an optical glass manufacturer as well that developed many types of new glass. Features and history of the lensThe feature of this Nikon's first "3, 2-8" is the complete removing of chromatic aberration with using the extra-low dispersion glass (later, Nippon Kogaku-made material was named ED glass). Nikon's first "3, 2-8" lens was born from the wish of taking sharp photos with the shutter speeed as fast as possible at the event of Sapporo Winter Olympics. Among Japanese lens-lovers, 300mm f/2.8 lenses are friendly called "San, Ni-Ppa (3, 2-8)".
The number of production reached mere one hundred and several tens.Later, Nikon original IF (Inner Focus) system was developed and the automatic aperture control and AI (Automatic maximum aperture Indexing) system were adopted and, AI Nikkor 300mm f/2.8 IF-ED that established firmly the fame of "3, 2-8" was released in February 1978.Then a protection glass filter was added to the front lens in order to protect the ED glass.Time passed further to Autofocus age and it was modified to AF model in Oct. Later, it was applied with the multi-layer coating, and then, improved to the one adopted Nikon's ED glass.Since this lens was not sold to general users from the beginning to the end, it was never printed in a catalog. At that time, it lacked the title of "ED". 1972 exclusively for the press field. First, this lens was released in Jan.
SHIMIZU, Yoshiyuki introduced in Tale Five.Though it is not well known and to our surprise, this lens has the covering power enable to cover 6 x 6cm format.It was originally designed so as to be switched to "Bronica Nikkor".First, take a look at the cross sectional view of NIKKOR-H 300mm f/2.8 (Fig. 1 Cross-sectional view of NIKKOR-H 300mm f/2.8The optical design of NIKKOR-H 300mm f/2.8 was made by Mr. In November 1996, then, AF-S Nikkor 300mm f/2.8D IF-ED with further renewed optical system and Nikon original built-in SWM (Silent Wave Motor) was released.Fig.
Therefore, defocus characteristics in the periphery improve.At f/8~11, I don't think there is a big change in sharpness. However, as vignetting disappears, defocus images are kept circular up to the periphery of the image field. Defocus characteristics are also excellent.A reflecting object was intentionally included in the background of the frame but the off-axis aberration was not generated.As the covering power is so big as to cover 6 x 6cm format, insufficient brightness of the edge of image field never occurred.Stopping down to f/4~5.6 improves the sharpness, but there is no distinctive difference since it gives sharpness even at the full aperture. As nearly back-lighted subject was selected, defocus characteristics, reproduction of the shadow and gradation, not to say sharpness may be checked.Imaging characteristics of this lens, full of softness even in the sharpness will be best suited for the portrait.Reproduction of the shadow and clear color rendition are indebted largely to the adoption of extra-low dispersion glass. Imaging characteristics and performance of the lensWhat are the imaging characteristics of NIKKOR-H 300mm f/2.8 ?As evaluations are always subjective, please take my comments as my personal opinions, just for your reference.In the vicinity of full aperture (f/2.8~3.5), it gives sharp image, good color separation and full gradation from the center to the periphery, as imagined from the aberration value.Example photos were taken at the relatively medium distance and at the aperture of full open to f/3.5. The oblique lined lenses are made of extra-low dispersion glass (later called ED glass).Rear three lenses, including two lenses stuck together, have a power of concave lens in total and correct well curvature of field and upper coma.Characteristics of aberration of this lens is that chromatic aberration is well corrected, spherical aberration is straight and a little under-corrected, astigmatism is small and curvature of field has the tendency of being minus.We can expect from these that high definition and clear color separation and smooth gradation and excellent background defocus.
I realized all the more keenly the difficulty of product development. To my surprise, the normal (non-automatic) stoop of this lens was very easy to use, with ease of checking of the depth of field and defocus characteristics.It was well understood why the normal stop which we felt as disadvantageous was adopted by the recommendation of the field staff. I repeated to shoot for these examples at f/2.8~5.6.
Our desks are covered with a pile of documents and papers to be submitted are easily delayed. WAKIMOTO, Zenji and, later, played an important role in administration of the budget and general affairs, making blue prints and reports in the lens designing department of Nippon Kogaku K.K.I've heard that she was the first woman employee who was raised to the rank equivalent to the manager in Nippon Kogaku K.K.We, optical designers, are all a little strange. In her younger days, she made the calculation of ray tracing with an abacus and a table of logarithms beside Mr. HATANO, Reiko was just a woman as called "Ryosai-kenbo" in an old Chinese proverb, meaning both of a good wife and a wise mother. HATANO, ReikoThe story is not about a lens designer this time, but about a woman who worked as a helpmate of a lens designer for many years.Ms.
UDAGAWA of prototyping.Users' talk of their experience and advice must also be highly appreciated. There are many people who labor in the background like Ms. HATANO that I can introduce old lenses, with reproducing data from reports.She handed down the history of departments of optical design exactly with careful attention and tenderness particular to a woman.Owing to these precious materials, I can look back the history of optical designing of Nikon exactly.Development of excellent products is not made by designers only. Honestly speaking, it entirely owes Ms. HATANO when they were in trouble.
