For those interested, it was taken with the Tamron 11-20 f2.8 zoom at 11mm and f8. I like a lot about this lens, especially it's weight and performance. I haven't decided if I like it enough more for travel than my Fuji 10-24 f4 to keep it, but the light-weight for an f2.8 wide-zoom is compelling even though it covers less range.
