A stroke of luck.

I was mooching around North Beach, the Italian section of north east San Francisco, and chanced on an interesting clothing store. All the help was busy so I sneaked into the workroom in the back and Pow! There it was. All I did was press the button.

Nikon D3x, 35mm AF-S f/1.4 Nikkor at f/1.4, ISO 800. The Nikkor may lack the raw resolving power of the 35mm Sigma equivalent at full bore, but it holds up nicely here.
