I like the Pana setting on X100 (img)
Nice shot. No exposure banding or errors stitching that I can see. I like the composition too, with the walkway bridge in the centre.
I'm taking a lot more panos with my x100 these days and getting great results. Sometimes I get exposure banding so switch to fully manual mode, which usually helps. The other day I was getting nice results just in aperture priority mode. I've read somewhere to set the shutter at 250 for best results - will try that too.
