This rumor is based on a tweet from somebody that works for a camera shop in Japan. I have a reason to believe that his information is correct: Nikon is rumored to release a new Nikkor 20mm f/1.8G lens with Nano coating (see patent). Here is the translation:
D750 to be announced this month, specs: 6.5fps, AF unit same as the D810
D610 might be discontinued soon
At the same time a new lens will be announced: AF-S 20mm f/1.8G with Nano crystal coating
This is fun
I have been saying for a while that Nikon will release a new wide angle and a tele lens – maybe this 20mm f/1.8 will be one of the two rumored lenses?
Update: the Twitter account is now private and the tweet is no longer visible to the public.
