Is the sony fe 24 105mm f 4 g oss worth it?
Yes, I think it's a sensible buy if you want one lens that covers most of what you shoot. The 24-105mm range takes you from wide street and landscape views to short telephoto, and the stabilisation helps when light is dim. At f/4 it won't give you much background blur or help much in very low light, so for that you'd want a fast prime alongside it.
It works on full frame and on APS-C. On APS-C it frames roughly like 36-158mm on full frame, which is still a useful range. If you're packing light and want one lens for nearly every picture, it's a strong choice, as the travel guide explains. For a sense of how to build a kit around it, see your first lenses.
