This little 27mm lens for Fujifilm X-series cameras is probably the most annoying lens I own, and yet it's so good that I'll probably never sell it.
Fuji XF 27mm f/2.8 lens review with samples
The Fujifilm XF 27mm ƒ2.8 R WR is a tiny "pancake" lens, so called because it barely protrudes from the camera body it's mounted on. This is Fujifilm's second version. Internally, it's the same. Externally, you get weather and dust resistance and an aperture ring (the original required you to use the camera's menus or dials to change aperture).
This older design is slow to focus, noisy when it does so, and its ƒ2.8 maximum aperture makes it difficult to blur the background behind your subject. Still, the optical quality is stunning and the size is so convenient that it's the perfect travel and carry lens for my X-Pro3.
Optically, the 27mm pancake is simply amazing. It is more than sharp and if you can blur the background, the quality of that blur is both pleasing and unobtrusive. The photos you take with this lens are indistinguishable from those taken with larger, fancier lenses.
