what is nikon plena

Nikon Plena is a new lens that Nikon is teasing and will be released on September 27th. The name Plena has several meanings, including "full" or "plenum," which can refer to an enclosure containing gas held at a higher pressure than its surroundings. Some speculate that this is the beginning of a line of f1.0 lenses, with a 35mm f1.0 being a possibility. The name Plena may also be an attempt by Nikon to control the nicknames that lenses get.
