Holy guacamole! Just did my first shoot with the Fuji X-Pro 1 and wow am I impressed! Thankfully, I received my copy just after Fuji released the latest firmware update which even further improves focusing. Having been an avid Fuji X100 shooter, I've grown accustomed to the quirky nature of the beast and slow focusing, however the X-Pro 1 is nimble by comparison.
I'm just getting started using this new camera system and can say that it's a pure joy. Everything about it, from the handling, to shooting, to the image quality. I haven't even begun to add flash to the mix, but lets just say that it won't be long!
