In this video, I’m digging into the latest FX3 II / A7S IV rumor that honestly has the potential to be either genius or a total misread from Sony: a partially stacked 16MP full-frame sensor, supposedly landing around 2026. The headline claim is speed—rumored ~240fps readout performance—which would mean rolling shutter could be nearly a non-issue. Pair that with the big pixel pitch you’d get at 16MP, and you’re looking at the kind of low-light performance that made the A7S line legendary in the first place. But here’s the catch I can’t ignore: resolution. If the ceiling is roughly 5K, that raises real workflow questions in 2026—open-gate options, cropping flexibility, reframing for vertical, and just general future-proofing when everyone else is pushing 6K and 8K. So I connect the dots on what Sony might be trying to do strategically, who this camera would actually be for (pure filmmakers vs hybrid creators), and why “speed and clean low light” still matters—but only if Sony doesn’t box creators in with limited resolution choices.
