I can't speak for the X-T4 but I currently have an X-T3 and X100V and have previously owned an X-T30, X-T2, X100F and X100T (that's three generations of Fuji sensors).
I shoot with my cameras set to RAW but then use X Raw Studio to 'develop' the images I want to keep so although I am technically using camera JPEGs I have the flexibility to adjust exposure, WB, film sim etc. before I process the JPEG. For me, I enjoy the constraints of a limited set of adjustments and there's a magic about t
I own a Ronin SC. Compatibility with my XT-30 similar to if it was a brick. Anyway I see no issues, Ronin SC works well as a gimbal without a specific DJI features. I start and stop filming pushing a button on a camera. Focus wheel works well with all my lenses.
Just to provide a balance of views, I haven't missed the D-pad at all and yet I've also disabled all touchscreen functions, which to me feel gimmicky and unsuited to a camera like this. Fujifilm has to walk a very thin line in balancing the wants and needs of so many photographers and I think they do a good job overall. If you're regularly changing white balance, and film sims etc. on the fly then I can understand why the D-pad is important and a touchscreen replacement wouldn't cut it for me ei
Matt, I have this lens and have taken many thousands of shots with it, mainly sports pictures. I'd say that somewhere in the high 90% of the shots are tack sharp. I use AFC, IOS on and off, and hold the lens and my X-T2 on a monopod. Some of the games are at night with stadium lighting and many are in bright sun and have no issues with sharpness. Seems like your lens needs to go in for service.
