Might be worth a look see...now that Nikon is coming out with that Mirrorless. https://www.lenstip.com/141.1-article-A_visit_in_the_Nikon_Museum_in_Japan.html Please see All chapters...and you may decide to stay with this Cherished brand. |

Slightly heavy reading in places but well worth the effort, it makes a good partner with the Museum link. https://www.imaging-resource.com/news/2018/07/17/pixels-for-geeks-a-peek-inside-nikons-super-secret-sensor-design-lab This explains the excellence of the recent crop of Nikon cameras especially the D850 and high expectations for the ML. This must have been heavily censored, one can only imagine what we aren't told but it must be even more amazing than what we do discover. |

Thanks for this link Robert. A little late with this response, but rather than a quick read , I practically " studied " this article and the link to Nikon`s Glass-making facility, the Hikari glass works. https://www.imaging-resource.com/news/2018/04/17/glass-for-geeks-an-in-depth-tour-of-nikons-hikari-glass-factory I had thougt that Nikon allways bought glass from Minolta , like many others I find it an Interesting read indeed , and had no idea that the concept starts with a camera to which a particular sensor is designed..with the most challenging being the D850. Quote: This is one area where Nikon's dedicated sensor design has paid off for them: The D850 has the first true ISO 64 capability in an SLR. (Other cameras have special “Lo†ISO settings that will get there, but those come at the expense of poor tonal qualities and blown highlights.) Sanbongi-san told me that they developed the D850's true ISO 64 capability in response to requests from motor-sports shooters, who wanted to shoot at large apertures and slow shutter speeds, so they could pan to follow the race cars while dramatically motion-blurring the background. I don't know enough about sensor design to understand the details of what's involved, but when I asked Sanbongi-san what his team's proudest achievements were, he mentioned the D850's true ISO 64 first. End quote !! And now I know what causes " stuck or hot pixels " quote : No Snow: Leaky pixels = stuck pixels! At the other end of the scale, when there's very little light, we want to make sure that the only electrons in the photodiode got there as a result of incoming photons. It turns out that photodiodes “leak†charge, letting random electrons creep in from the surrounding silicon. This shows up as “hot†pixels that look bright whether light is falling on them or not. Even if a given pixel doesn't stand out on its own, random charge leaking into a sensor's pixels from this so-called “dark current†can be a significant cause of image noise. (Again, to our more knowledgeable readers, yes, shot noise is a big part of high-ISO noise, and there's nothing to be done about that at a sensor level; it's just math. But minimizing both bulk and surface leakage while maximizing well capacity and maintaining high readout speed is a significant challenge.) Sanbongi-san pointed to the D5's sensor as a case where they'd maintained excellent quantum efficiency and very low leakage, while still maintaining high readout speeds. end quote. However , when it comes to Nikon-pixels, I remembered the following... From : https://en.wikipedia.org/wiki/Nikon_D1 Quote : In a later "behind the scenes" interview published on the Nikon website[7] it was revealed by the General Manager of Nikon's Imaging Development Management Department that the sensor developed for and used in the D1, and subsequently the D1H, actually used 10.8 million photosites rather than the 2.7 million that had previously been suggested. This allowed multiple photosites to be grouped together into units that formed the final pixels in the image, contributing to the sensor's high sensitivity and excellent signal-to-noise ratio. End Quote. So I have since learned to look at " Output " in MBytes rather than bother about pixels, especially when it comes to Nikon. I am convinced that Other manufacturers go through great lengths themselves to make a fine product, yet Nikon has made many innovative contributions , unrivalled by others,beginning with the D1,which Propelled the Entire Pro-oriented photo sector into the realms of Digital photography , as it was Affordable and of High Quality to boot. Enter those new mirrorless camera`s of which I doubt that they will replace the " Big D " camera`s , but perhaps are a solution for those of us who need something at lower cost..lesser weight , with a capability close to the Big D line-up. or am I completely out of step with reality.... |

I think you are spot on. Glad you found the energy to read and absorb the link. I just wish some of the 'armchair experts' would take the trouble too. There are way too many people with access to the likes of YouTube who pontificate without having a clue what they are on about. Just jumping on the band wagon to earn a few quid from advertising hit money. We still have to see what the new Z cameras can do in real life but I really do have high hopes. Nikon are as serious about this as it is possible to be. Maybe not with the first iteration but it's a mighty good foundation. |

Apparently there is to be an exhibition of prototype Nikkor lenses which maybe never made it to production. Is mainly in Japanese but some of the titles are in English. https://dc.watch.impress.co.jp/docs/news/event/1142394.html |

I wish it was on line, all those Proto types.... From this article TWO lenses are shown , that I Would have gotten, ...When the 50 - 300 f4.5 came out, I said to myself... " Why not a tad shorter , 35mm would do nicely, and a tad longer , 400mm would be GREAT , with Full meter Coupling !!! This was in a time when Nikon`s longest Tele lens with Full meter coupling was the 300 f4.5 , longer ones had Stop Down metering only !! That 1000 f11 hybrid was something I longed for as well , after all , a Short ,Lightweight with Variable Aperture Tele lens...what`s not to like..?.. Now it shows , they made them ,yet Refused to Sell to me..( scof )  I wonder what other Goodies on my wish-list they have made. |

On a second look ...that`s a Distance scale I saw on that 1000mm... |

In due course I hope to be able to provide a link to more information. I know of at least two people who plan to go and intend to take many photographs. The exhibition might even be displayed on-line perhaps. |

Is Nikon up to something ?...the mirrorless camera`s and the Museum at the same time..what are they cooking ? |

Perhaps tying to remind past and present customers they they are a serious manufacturer, proud of their past and striving for the future? The item I posted about the R&D department is perhaps another example of Nikon reminding the photographic community they are seriously committed. |

Just caught up with this very interesting. Liked Nikons birth date of 25 July 1917 now I know why I like Nikon my BD 25th July 1940! |
