I visited Paris in August last year, and decided ahead of time that I could either take all my gear (which included my 5Dii at the time) and carry this around all day, changing lenses and packing gear, or go simple and take just the X100, I've traveled with the X100 before and have been thrilled with the results, as such this is all I took, along with a few batteries of course.
My main photographic aim for the trip was to get some standard travel/tourist photos as well as a bit of Parisian street photography all the while enjoying the sights this wonderful city has to offer. Having only a 35mm (equivalent) lens meant I would not be tempted to switch out lenses to achieve what I wanted and instead was forced to focus more on composition and subject.
Another advantage of traveling light and with the Fuji cameras is I don't look like a photographer and as such am less of a target for the numerous pickpockets and street hustlers Paris has to offer, if you've never been the best bet is to stay aware as it seems around each corner someone is trying to hustle you.
That fact aside Paris has some wonderful sights and I made the most of my time there, visiting all the major sights and taking in a bit of culture, as well as finding awesome places to eat. Everywhere you go there are incredible buildings, and a mix of people to photograph, it's worth it if you have never been for sure.
One of the most incredible places for me were the somewhat disturbing catacombs that run underneath Paris, these underground tunnels house the bones of residents past and I can say with some certainty that I've never seen anything like it. It was however crazy dark but the X100 with it's leaf shutter (which allow to you hand hold at low shutter speeds due to no mirror flick back) and high ISO made it possible to get the shot with ease.
Below is a mix of stuff from Paris and elsewhere that I've yet to post anywhere else, so take a gander through and enjoy!
