Fujifilm GFX 100S vs Fujifilm X-T5
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 GFX 100S leads at 102 million effective pixels vs the X-T5's 40.2.
- Burst — electronic: the X-T5 leads at Approx. 20fps (1.29x Crop) vs the GFX 100S's Approx. 2.9fps.
- Burst — mechanical: the X-T5 leads at Approx. 15fps vs the GFX 100S's Approx. 5.0fps.

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.
