Somedays, most days if I’m truthful, I just prefer to walk with a small, lighter weight camera and lens combination. These days that would be my X-Pro2 with the 18mm lens which is an effective 28mm focal length. It is an older, noisy focusing lens, but it does the job and I like the focal length when I can also get up close enough to static subjects. I find that it makes a nice documentary lens. I should use it more often. I wish Fujifilm would update the lens with a quieter focusing motor and make it weather resistant.
If I had more use for this focal length; i.e. if I went anywhere worth documenting what I saw, I would probably buy a small pocket camera with this focal length … maybe the Ricoh GRIII camera, especially if I wanted to make B&W images.
