I just recently acquired the 18-135mm lens. And while, it's nice to have such a long focal length range, the lens is rather big and bulky and not very fast. However, it's OIS capability is pretty dam good at 5 stops (so Fuji claims). I've taken it with me while hiking about locally and it does produce some nice images on the X-T2. And, even with all that said, I still prefer the kit lens, 18-55mm f2.8-4 with OIS over any other lens I have. I just wish it was weather resistant like the 18-55mm f2.8. Unfortunately, the latter has no OIS and while I like the idea of it, it's still bigger and bulkier than the kit lens. The kit lens is so versatile and I can shoot water falls with it and the lens closed down to get that dreamy silky effect without a tripod.
