In this video, I break down the latest Sony rumor that’s got everyone hyped—and honestly, a little confused: a new 16MP full-frame sensor prototype that could end up inside the FX3 Mark II or the long-overdue A7S IV. On paper, the leaked specs sound insane. We’re talking a partially stacked design with a rumored 240fps readout, a huge 7.2µm pixel pitch for monster low-light, every-pixel PDAF for fast autofocus, and DCG HDR tech for better dynamic range. If Sony nails the real-world performance, this could be the “speed king” setup a lot of video shooters have been waiting for. But I also explain why this might be Sony’s huge gamble—and why it could fail for a lot of creators. At 16MP, you’re basically capped around 5K, and in 2026 that starts to feel dated when Nikon and Canon are pushing 6K/8K and open-gate flexibility. For anyone delivering both horizontal and vertical content, the lack of open gate is a deal breaker, and Sony’s recent habit of “safe” upgrades doesn’t help. At a rumored $3,500–$4,000 price, I’m asking the real question: is 4K 240fps enough to ignore the missing resolution and modern workflows?
