The first image is taken of a relative leaping into the air. The screenshot is at 100% in Camera Raw with no post-processing (other than Camera Raw conversion from native Fuji .RAW format). Taken on the 501-40mm F2.8 lens at F4, 1/500s, ISO 400 and @ 105 mm focal length. I had the camera set on tracking with eye/face detection on.
As you can see, the image is sharp and is an example of how fantastic the X-T2 is at tracking and image stabilisation, even when hand-holding the lens. It's not the heaviest zoom but neither is it lightweight, due to the solid build.
The second image is taken of Oldham town hall, in Greater Manchester. Despite aerial haze, you can clearly make out plenty of details. Amazing for a shot taken some 4.3 km (2.68 miles) away! Again hand-held with image stabilisation on. Again, taken with 50-140mm with 1.4x T/C. Taken at F10, 1/320 secs, ISO 200 and taken at @ 295mm equivalent. Again, no post-processing other than Camera Raw conversion.
The third image was a grabbed shot of a magpie flying low across a field. It was quite a distance away but I was impressed that the camera was able to lock on and track the bird, despite it being a fast mover! Once again, I am very happy with the performance of the 50-140mm and 1.4x T/C combination.
