Rory Prior’s review of Fuji’s FUJINON XF 14mm f/2.8 R is a fantastic, not only because it mentions this site at the bottom, but it includes some excellent insights. It’s a great read for anyone considering what’s still one of Fuji’s best lenses to date.
With the sheer ubiquity of 18-55mm (28-70mm) lenses, people are used so seeing images at those focal lengths. That means lenses that break out of that range immediately have the potential to create more interesting pictures. The downside for the photographer is that it can make composition and getting the right exposure more complicated. You’ve potentially got to get a lot closer to subjects to make them fill your frame, then you have distortion to worry about, especially when shooting people.
