Is the fujifilm mkx 18 55mm t2 9 worth it?
Honestly, it depends on how you shoot. The Fujifilm MKX 18-55mm T2.9 is a manual-focus cinema zoom with geared rings, and it has no autofocus and no stabilisation. If you want a grab-and-shoot walkaround lens, it's the wrong tool. If you shoot video, or like deliberate focus pulls and smooth zooms, it's a good fit. It mounts on a long list of Fujifilm X bodies, from the X-E1 to the X-T30 III, and on APS-C it frames roughly like 27-82mm on full frame.
For most everyday photography, I'd look at an autofocus zoom instead. The travel guide explains the one-camera APS-C setup I'd usually suggest. For sensor choices, Sensor sizes is a good read. The lens page has the full specs and camera list.
