I love it when people use my images as their facebook profile pic.
Love - love - love it.
And now that facebook has that wide photo at the top of your page, now I want to see my photos up there too. On everyone's page.
I have a good wide lens, but now I want the BEST and widest wide lens - an ultra wide lens, and since I shoot with Canon, it would be this lens: the Canon EF 14mm f/2.8 L II USM Lens. It's rectilinear, meaning it shows straight lines as straight, it doesn't produce a fish-eye look.
Want - want - want.
