For my two-days trip in Napoli (Naples: I somehow dislike using the Anglo-Saxon name for this Italian town), the photographic gear choice was quite easy: I wanted light and unobtrusive. I went for an iPhone 5 and a Fuji X-T1 fitted with a Nikkor 50/1.2 lens. Although normally I like short tele lenses, I felt that for Napoli I reached more often for my 35mm-e equipped iPhone. Actually I have already decided that my next trip will see me together with a serious wide angle lens.
It was December 2015 but the air was still all but freezing cold and walks were easily a good choice for visiting the town.
Personal choices aside, this may well be explained with the fact that I mostly liked touring the old town, such as Spaccanapoli and the Quartieri Spagnoli, that most certainly deserve a second and a third visit, at least, in such as they closely resemble an open-air theatre where the actors are the whole people of Napoli.
Plenty is said about Naples, good and bad, so that it is very difficult to have a look around the town with virgin eyes. The scenes that develop under your own eyes are, someway, different from what you expected, because this expectation was intense and — probably — misguided. Most probably, the idea you already had was wrong; most probably, the lens you had mounted on your camera was not your best choice!
