Fujifilm x t200 vs fujifilm x t4?
The two are closer than the names suggest. Both are APS-C mirrorless cameras on the Fujifilm X mount, with a similar 24 to 26 megapixel sensor, so the lenses are the same. The difference is in the body.
The Fujifilm X-T200 is the cheaper, lighter choice, with a large vari-angle screen. It has no stabilisation in the body, so I'd pair it with stabilised lenses like the Fujifilm XF 18-55mm f/2.8-4 R LM OIS for slow shutter speeds.
The Fujifilm X-T4 is the one I'd choose if you can afford it. It has stabilisation in the body and a fully articulating screen, and I think it's a strong used buy. Every lens on the X-T200 list also fits it.
