After yesterday's rumor, a reader posted a link to a Nikon AF-S Nikkor 50mm F1.2G patent on a Japanese site (English translation):
- Focal length f = 51.63mm
- Brightness F = 1.25
- Overall length: 94.94mm optics
The patent was filed on July 2nd, 2008 and was published on January 21st, 2010. I could not find any reference to this lens in the US Patent Office - it seems that this patent was filed only in Japan (just a reminder that patents do not guarantee a future production version).
I am curious to know if the tips I received are based on this patent or they are coming from different channels.
UPDATE: for comparison, here is the lens diagram of the current Nikon 50mm f/1.2 Ai-S model (source: Nikon):
UPDATE #2: Here is a direct link to the patent - go to this website and search for "Kind code = A" and "Number = 2010-14895", then click on the link "JP,2010-014895,A".
