Fujifilm X-T3 vs Fujifilm X-T4
Every spec below is quoted from the makers' official pages — where a figure isn't published we say so rather than guess. Sizes are drawn at true relative scale from published dimensions, and the bag-fit row is computed against our measured bag catalog.
The 3 biggest published differences
- Resolution (MP): the X-T4 leads at 26.1 millions pixels vs the X-T3's 26.1 Megapixels.
- Burst — mechanical: the X-T4 leads at Approx. 15fps vs the X-T3's Approx. 11fps.
- Battery life (CIPA): the X-T4 leads at Approx. 500 frames (Normal Mode) (Approx. 600 frames Economy Mode) vs the X-T3's Approx. 390 frames (NORMAL MODE).

Spec values are the manufacturers' published figures, compared factually — we don't rank cameras. Fit verdicts are planning estimates from published interior dimensions, not guarantees. See methodology.
