The X100V is the fifth iteration of the X100 series, and it is perhaps the biggest upgrade to the series since the launch of the initial camera. For the first time since the original launch we have a new lens, weather sealing (when using the filteradapter), and a two-way tilt screen! On top of that the camera is now built in a completely new material, which is Aluminum. The camera has really had a complete overhaul while retaining what made the X100 series so special in the first place. Portability, very good IQ, silent leaf shutter and gorgeous drool-worthy design.
