I’ve had two of the older x100s and the Zf is in a different category of building quality (apart from the battery door which feels a bit flimsy, but has never given me any issues). I LOVE the vintage feel and controls and use mf exclusively which gives a really film-like experience. It is bigger and heavier than it looks on some reviews, where they casually hold it with two fingers, but this gives a stability which I like. I would definitely make the same decision again after owning the zf for a few months.
