Released in 2020, the X-T4 was the first X-T body to add in-body image stabilization, a genuinely significant addition to a lineup previously reliant on stabilized lenses alone, paired with the same 26.1-megapixel sensor generation used across most of Fujifilm's X-series at the time.

The X-T4 also introduced a fully articulating screen, replacing the X-T3's simpler tilting design — a change aimed at improving video usability that drew some mixed reactions from stills photographers who preferred the previous tilt-only mechanism for tripod work. Its stabilization rating of up to 6.5 stops was genuinely competitive with full-frame systems at the time, a meaningful achievement for an APS-C body given the smaller sensor-shift mechanism it required compared to a larger full-frame sensor.

Fujifilm also improved the X-T4's battery life substantially over the X-T3, addressing one of the more common criticisms of Fujifilm's earlier X-series bodies among all-day shooters.

Frequently Asked Questions

How does the X-T4's sensor compare to the newer X-T5's?

The X-T5 moved to a 40.2-megapixel sensor with a meaningfully tighter roughly 3.02-micron pixel pitch, giving more resolution but a shorter safe astro shutter speed under the NPF rule at a matched focal length. The X-T4's 26.1-megapixel sensor trades some resolution for a slightly more forgiving pixel pitch, which some astro shooters genuinely prefer for that reason alone.
