Thanks! However, I think I mislead you with the 'tripod' comment! These are all taken at low ISO with the help of a
GorillaPod. What I meant was that the x100 and GorillaPod are pocketable and certainly a lot more discrete.
Tower Bridge: ISO 200, F5.6, 3.1s, -1EV. The camera JPG was pretty good but I used the Raw and did a little correction of the verticals in Photoshop along with the usual highlight/shadow adjustment. From the image as posted it's hard to tell but the combination of the strong lighting and aperture gives an incredibly sharp image - I was amazed how much detail could be captured.
Millennium Bridge is similar to the above but the London Eye Was f2, 0.6, -2.
