Nikon has been busy. They issued a Firmware update on the D4 and D800. This firmware update fixes several issues.

They’ve also filed a number of patents. One of which is an 18mm f1.8 FX =full frame lens. I hope this one comes about, and is affordable. I’d buy it to add to my Prime lens collection. Currently my fastest wide 18mm prime is f3.5. It’s a wonderful old lens and works great for being 37 yrs. old, but faster is better when shooting the stars at night.
They’ve also filed a patent for a 20mm f1.8mm for those of you who like the 20mm focal length.
