Interesting article on the holy grail of lenses

Don't ever let anyone tell you Nikon didn't make a super wide angle for crop cameras!

wow,, 29K hahah,, now that would be a rich photographer that would buy that, I would be afraid of tripping. I have a Nikkor 15mm 3.5 that has a very similar build, which you can pick up for around 1000 dollars, while not 13 mm, it is built with the same quality, and feel, a real joy to use.
