Working for American companies meant travelling to Silicon Valley numerous times (not that I complained - I love California!) I visited the Leica showroom - always a mistake -and "invested" in a SUMMILUX-SL f/1.4 50mm ASPH lens for my SL camera. The colour rendition and the bokeh were so good and helped me justify the exorbitant price of the lens!
San Francisco is a great location for street photography - nobody seems to worry about having their image taken - other than the lady who held up a newspaper - I love that shot better than if she hadn't!
