When you need to be cheered up - go to the Regent's Park right now. The Queen Mary's Rose Garden is in full bloom at the moment and you can enjoy the scent of dozens of different roses there.
I took the visit of the rose garden to test the highly acclaimed lens Canon 50mm f1.4 and It was so worth taking it with me. In comparism to the Canon 50mm f1.8 the bokeh is even softer. The entire handling feels great and I am almost sure that this lens will be my next investment.
But now enjoy a travel to the rose garden - unfortunately it's not possible to capture the scent within photographs.
