Facebook just showed me this image (posted 3 years ago today on FB). It was taken with a Leica M9 and a borrowed 50mm Summilux ASPH. My pal Dave loaned me the 'lux for the long weekend. This frame caused me to abandon my 50mm 'cron and buy a 50 'lux. Today, this lens is still one of my all time fav's. It delivers consistently and does great wide open. According to the EXIF data, this shot was taken at f2, but I recall it being shot wide open.
