I have the 18-55 and coming from primes on my Canon I tend to forget about the zoom. I do not like that the aperture changes with the length and looking at getting a prime for the Fuji X-T2. Most of my travel photos with the Sony rx100 iv are around the 28 to 35 range and the last trip the Fuji was around 25 to 35 length. Two used ones are at my camera store, the 1.4 and the 2.0 Which one is sharper? I am open to looking at other lenses.
