Lens suggestion for trip to San Francisco

18-135... best of your owned for this trip
maybe one small fast as backup for some eve walkabout...28 or 50

HOWEVER
I cant imaging NOT having a 10-22 with you all the time
... when you own a nice 1.6 camera

THAT would be my one lens (then toss in a small fast one)

My hometown...

I revisited ....walked all over ...all across the town ...all day shot the 10-22 almost exclusively...

I did have a 70-300 I.S. at the time and used it for a few shots...

yrs LATER took a 16-35 II on 5d2.....and had a new 70-200 f4 I.S. at the time....

again walked all over...and same with Sausalito, Angel Island, Tiburon ...and Mt Tam ......

Wide (zoom) is the way - IMO

now with 5D3
I would take my 14L II and ... maybe a 24-105...maybe.......
for morn/eve walks....35L and 85L ....both wide open
