Fujifilm
Known for long firmware support on X-series bodies, often adding features years after launch. The X mount is APS-C only, which keeps lenses smaller and lighter than full-frame equivalents.
Fujifilm’s habit of shipping meaningful firmware updates after launch is why older X bodies age better than their spec sheets suggest. The trade-off is the sensor format: there is no full-frame X body, so a Fujifilm system is an APS-C system for good.
