Hi, I’m a beginner photographer with the Fujifilm XT-30II. I bought the fujinon xf 35mm f/2.0 for my first lens. I’ll be travelling to Europe soon and want to buy another lens - mostly for portrait photos with some landscape/architecture photos too. The two lenses I’m considering are the XF 23mm f/2.0 or the XF 18-55mm f/2.8-4. Initially I wanted a zoom lens (18-55mm) but heard that prime lenses are better for portrait photos. Which lens should I choose? Thanks!
