Fujifilm x e3 vs fujifilm x pro2?
Both use the same 24.3-megapixel APS-C sensor and the Fujifilm X mount, so every lens in the catalogue that fits one fits the other. Neither has stabilisation in the body. The X-Pro2 was announced in 2016 and the X-E3 in 2017. The X-Pro2 page and the X-E3 page have the full specs.
Since the lenses are the same, I'd choose between them based on which body you like handling. For an everyday kit, pair either one with the Fujifilm XF 23mm f/2 R WR for a standard view, the Fujifilm XF 35mm f/1.4 R for a fast prime, or the Fujifilm XF 16-55mm f/2.8 R LM WR if you want one versatile zoom.
