Summary: very crisp and clear from corner to corner. I had a 20mm on my 35mm camera for 25 years shooting landscapes it was always my favorite. This is now my new favorite with 35mm equivalent of 18-35mm. With that range of focus even at this price its a bargain!
Summary: This lens gives the Nikon 1 system a lot more versatility. The image quality is outstanding and it is extremely light. All my Nikon 1 lens weigh no more than a single DSLR lens so travel photography is now a joy. Just wish this lens came out last year when I had gone to Europe. Could have really used it there for all the tight street shots.
Summary: The big knock on the Nikon 1 system has been two-fold: the small sensor and the lack of lenses beyond the kit zooms (the 10-30 and the 30-110). No one who has actually used the camera complains about the sensor size any more for normal photography. I've printed 3 11x14s shot from the same pouit by three cameras -- the Sony RX100, the Nikon D3100, and the Nikon V1 -- and no one can tell them apart. This lens starts remedying the lack-of-lenses complaint.
Summary: I have been waiting for this landscape lens from the beginning. At 6.7mm there is visible distortion, but after photo processing can manipulate it. At 13mm, it is not there at all. This lens is always perched on the Nikon 1 in my bag.
Summary: This is an excellent lens. I no longer use my 10-30 lens for landscape pictures. I went on a two week vacation with my family out west, and I used this lens about 80% of the time. If you are contemplating the Nikon 1 system, buy the V2 body and the following lens: the 6.7-13, the 18.5 (for low light situations), and the new, non-motorized zoom 10-100. The new 32 mm f1.2 looks like a winner too, but at >$800 it is out of most people's price range.
Summary: This is one of the best wide angle lenses I have ever used. Extremely high contrast and color saturation. Total edge to edge sharpness and practically infinite depth of field when paired with the CX sensor of the Nikon 1 cameras. Objects less than a foot away are just as sharp as objects at infinity and this is right out to all the corners, not just in the center. The resolution of this lens easily exceeds the resolution of the Nikon 1 series sensors.
