So whenever I have a stopover somewhere and it's more than 3 hours or so ... I try to leave the airport and explore the city.
I was in Lisbon for a few days in 2011 so I kind of knew my way around.
Did get a few shots that I liked. It's a lovely city, beautiful and incredibly cheap.
I only nearly missed my flight due to busses not running when they were supposed to.... still had 5 minutes or so. Last call ... oh well. I think the set turned out well, especially for the extremely short timeframe I had.
35mm Summilux on my M9 ... of course
