Fujifilm x a7 vs sony a6400?
Both are 24.2-megapixel APS-C mirrorless cameras announced in 2019, so the sensor is a tie. The difference is in how you shoot. The Fujifilm X-A7 has a big vari-angle touchscreen and no viewfinder, so you compose on the back screen, which suits low or awkward angles. The Sony a6400 is small and very quick to focus, so it's my pick for moving subjects like kids, pets or sport.
Neither has stabilisation in the body, so choose stabilised lenses if you shoot in dim light. For a sensible everyday kit, try the Fujifilm XF 18-55mm f/2.8-4 R LM OIS on the X-A7, or the Sony E 18-55mm f/3.5-5.6 OSS on the a6400. Both are plain, useful zooms that cover most daily shooting.
