Is the fujifilm x t4 worth buying used?
Yes, I think the X-T4 is a strong used buy. It was the first X-T with in-body stabilisation and a fully articulating screen, and its 26.1-megapixel APS-C sensor still holds up well. Buying a body that's a generation or two old is one of the best ways to get a lot of camera for less, as the buying used guide explains.
Budget for a new genuine battery with it, because old batteries lose capacity. If you want a dependable everyday zoom, the Fujifilm XF 16-55mm f/2.8 R LM WR is a solid pick. For something lighter on the wallet, try the Fujifilm XF 18-55mm f/2.8-4 R LM OIS. For portraits and street, the Fujifilm XF 35mm f/2 R WR is small and easy to carry.
