This is a very wide angle shot on the D3 full frame camera. I used a cheap Nikkor, the 18-35mm 3.5-4.5. This lens is a consumer grade lens, very cheap plastic build, with poor quality rings, but with a fantastic image quality/price ratio. I am using that lens before investing in the new 14-24mm f2.8, a professional lens at least 6 times more expensive. Corners are reasonably sharp when closed down to f8 or more, center is always sharp.
