Sony brings its blistering burst speed to RX10 IV

Sony just announced a pretty substantial performance update to its superzoom camera lineup with the RX10 IV. While the new $1,700 RX10 IV doesn’t gain any extra range, that’s fine; the RX10 III already tripled the maximum zoom of its predecessor last year. It also has the same fixed f2.4-4, 24-600mm (25x optical) zoom lens with optical image stabilization. The big difference here is all about what’s inside the camera, and how Sony is bringing the RX10 in line with the crazy shooting speeds that its other cameras have become known for.
