This month I threw caution to the wind and had a go with my X20, hand held, Aperture Priority and no filters, JPG. I know - against all wisdom in the field of stitched panorama photography, however, I am surprisingly pleased with the results.
Obviously not the same IQ as the X-Pro1 but if this is the only camera I have to hand it seems it will deliver for me.
As always, comments welcome.
