One camera, one lens? Wow, much as I hate to say it (because I love medium format, both film and digital), that'd have to be one of my Leica M's. Maybe the M240 with a 35 Summilux, as in the pic below. Or, more likely, the Monochrom with the 50 APO, my most-used combination.
MFD was an easy choice for me, as I just wanted to leverage the Hasselblad V-system that I love. The CFV-50c does that in spades.
Glad to see some motorcycle love here. Sadly, I confess to having totaled my bikes on two of my three racetrack crashes. High speed, violent affairs... Nowadays it's just the street for me. Four bikes and not enough time.
And, yeah, Valentino is the man!
