As we get closer to Photokina, I start receiving more rumors about potential new products. A few days ago I got a hint about two new lenses: the 105mm f/1.4 I already reported today (announcement this week) and a new Nikkor PC-E 19mm tilt shift lens that will most likely be introduced around Photokina (September 2016).
Nikon has filed at least two patents for a Nikkor PC-E 19mm f/4 tilt-shift lens.
Nikon currently has three tilt shift lenses (24mm, 45mm and 85mm).
Here is the updated list of rumored/expected Nikon cameras and lenses:
