Honestly I am so fed up with this 16-80mm lens that came with my X-T5 kit. I bought this camera specifically for the 40 megapixel sensor but every shot I take looks soft and just... muddy? Its driving me crazy because I spent all this money on the body and the lens just cant keep up with the resolution at all. I was out at my daughters soccer game last weekend here in Seattle and the autofocus kept hunting and missing focus on her while she was running and I just ended up with a bunch of blurry junk. I really thought this setup would be a massive upgrade from my old Canon but right now I feel like I wasted my money.

I need something that is actually sharp across the whole frame and fast enough to keep up with kids. I have about 1100 dollars saved up for a replacement and I need it before our trip to Japan next month because I am NOT taking this 16-80 with me again. I just want one lens I can leave on the camera most of the time without feeling like I'm compromising on image quality every single time I press the shutter. What is the best all-around zoom lens for Fujifilm X-T5 that actually takes advantage of that high res sensor?
