Ricoh patents several lens designs for 1″ sensors – 25/1.8, 35/1.8, 50/2.4 and 70/2.8

Egami, a Japanese blog known for releasing patent specifications of lenses designed and made by all notable manufacturer, reports that Ricoh has patented four prime lenses for the 1” sensor format. 25mm f/1.8, 35mm f/1.8, 50mm f/2.4 and 70mm f/2.8. Supposedly these lenses are meant for industrial cameras (so called machine vision applications), which predominantly use C-mount and CS-mount.

Nikon patents 9mm f/1.8 lens for 1″ sensor format

Nikon 1 community has been debating whether Nikon will abandon the system entirely, ever since the DL series of compact cameras with the 1“ sensor was announced at the end of February. The last Nikon 1 related announcements – Nikon 1 J5 and Nikon 1 Nikkor VR 70-300mm f/4-5.6 announced in April 2015 and March 2014 respectively – were made quite a while back, which naturally contributes to the anxiousness of N1 users. The V3 being two years old and there being no sign of the V4, the next high-end model, doesn’t help matters either.

But as the Japanese blog Egami reports, Nikon could be working hard on a fast wide angle prime as we speak. The 9mm f/1.8 (24mm full frame equivalent) described in the published patent is designed for 1” sensors, which implies that it could also be intended for a DL series camera or a lower end Coolpix A model. As you can see in the schematic below, the lens has a moderately complex optical formula, consisting of nine elements. Just to put things into perspective, the 1 Nikkor 10mm f/2.8 has six elements in five groups, while the optically superb 1 Nikkor 32mm f/1.2 has nine elements in seven groups.

Rumor: collapsible Nikkor 70-300mm f/4.5-5.6 VR

I’ve already reported on the publication of Nikon’s patent application for a Nikon 1 Nikkor 70-300mm zoom lens back in November 2013. As it seems, Peter from Nikon Rumors has received additional info on the lens. According to his sources, the super-telephoto zoom will feature a collapsible design (like most 1 Nikkor zooms) and an advanced optical formula consisting of many exotic glass types, much like the patent linked above describes (6 ED and 3 fluorite elements). No other 70-300 has this many ED and flurite elements, indicating that the Nikon 1 70-300mm will have unusually high performance straight from maximum aperture. Nikon-1-native-super-telephoto-70-300 Continue reading

Nikon 1 Nikkor 70-300mm f/4-5.6 Patent

The hottest news at the moment is about a patent for a 70-300mm f/4-5.6 native N1 super-telephoto lens. It has a radically different (more advanced) design than the 70-300mm full frame Nikkor: 20 vs. 17 elements, 13 vs. 12 groups, 6 ED and 3 fluorite elements vs. “only” 2 ED elements. The following photo of a mock-up at the Nikon 1 announcement back in September 2011 could be the N1 70-300mm.
