I shoot with this lens for thousands of shots of my grandsons sporting events. I am using an X-T2 and have had the combo for probably 4-5 years, I have no play between the camera and lens. I use a mono-pod for nearly all shots, and Idonotice some rotational movement between the two, there is no horizontal movement of play between the lens and camera. If you are not having the issue with other lens', then the lens mount plate out be loose. As mentioned before, you need to get this looked at in order to get in-focus results.

I went through the look see process, but I have so many pictures in Lightroom (over 200,000) that I didn't want to switch. I came from Aperture on a Mac and switched to LR went Aperture was discontinued. Rather than switch to Capture1, I went to importing my RAW shots with Iridient X-Transformer into DRG files, and then imported the into LR. What a difference! Iridient is about $40 one time purchase, and now I have all of LR and Photoshop available. I love the sync ability of my photos with my iPad and iPhone, and have even edited some of the pics on my iPad with great results.
Anyway, if you have concerns about leaving LR and shots you have already stored there, try Iridient for your fuji shots.

I agree with Lrover. The 18-135 is my go-to lens for travel and just everyday shooting. Also, being WR, it is good out doors in all kinds of weather. The wide range of focal lengths makes it very handy. Take a look at the YouTube video by Andrew and Denae as Andrew goes over all the fuji lens and why he likes each one and for what.

I use this lens frequently. The thread size is 77mm.

When I travel, I find the 10-24mm and the 18-135mm zooms to pretty much cover everything I want to shoot. You might want to take your 23mm lens for shots in the hotel or boat you may be on, but the 18-135 is my go to lens for its wide range of zoom. the 10-24 is great in older cities where the streets are narrow, or trying to get that shot of a cathedral without having to back up a block. Both of these lens do a great job. 

I sold my 55-200 and got the 100-400. I shoot my grandkids playing football and Lacrosse here in the Pacific Northwest, so the WR was really important for me. (lots of rain in Seattle!) Fantastic pics on my X-T2. I have become the team photographer. I shoot at 1/500th, F10-11, and let the ISO float. Using LR on the RAW images give me lots of pixels to crop to the action I want. The pics get uploaded to a Shutterfly site for all the parents to see.
