The Fuji x100s was my first Fuji camera and is still my go to camera for travel and environmental portrait photography. This camera is light, compact and unobtrusive and can be made to be completely silent. This camera allows me to blend in and not look like a professional photographer.
The camera has an amazing sensor and lens combination that allows me to create incredibly sharp images with a high dynamic range.
Recently I've started using the x100s with an off camera flash and some Pocket Wizard triggers. The camera has a 'leaf' shutter which means it syncs with my flash at a much higher speed than a traditional DSLR. This feature, along with the built in ND filter allows me to use a shallow depth of field and a small flash when making portraits in bright conditions.
