Very sharp and the composition is good.

yes, It is the Nikkor 14-24mm F2.8. This lens is part of a family of three lenses (24-70mm f2.8 and 70-200mm f2.8 VR)

Pros.

Image quality is excellent. Good range from 14-24mm if using a full sensor camera. (Focal length changes if used with a crop sensor camera). large aperture thru the lens f2.8. Very fast in low light. 

Cons, 

Heavy, very expensive, you can not mount a Pol Filter on it. however, they sell adaptors you can mount around it and attach a filter. 

I love it, I would recommend it. Just be aware of the cons, if you decide to get one. But for Landscape photography is excellent.

I was reading a comment you posted on someone else photograph where you were telling the person how to upload/link his photos from his Flickr account. And I thought, I should do the same. I think, I already have one, I'm going to see if I remember the password and user name. If not I'll set up a new one. Thanks for the advice, I always appreciate your input..
