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.

The RX10 IV, in some ways, offers the same specs of the RX100 V in a different form factor. It uses the company’s stacked 1-inch, 20.1-megapixel Exmor RS CMOS sensor, and combines that with the ultra fast Bionz X image processor to allow shooting speeds of up to 24 frames per second with autofocus and autoexposure tracking. The RX10 IV can shoot at that speed for up to 249 images before the buffer is full, too. These are all huge improvements over the RX10 III, which topped out at 14 frames per second and only allowed for autofocus tracking at speeds of up to 5 fps.

A major internal upgrade from the RX10 III

The size of the RX10 IV means there are a few solid benefits to picking it over the RX100 that go beyond the extra zoom. It has 315 phase-detection AF points that achieve focus in 0.03 seconds, according to Sony. The 1.44 million dot, 3-inch screen on the back is now a touchscreen, too, which is somehow a first for Sony’s RX cameras. And there’s a 2.35 million dot high-contrast OLED electronic viewfinder.

As for video, the new RX10 falls about square in line with the capabilities of Sony’s other RX cameras. It can shoot 4K video with full pixel readout at 30 or 24fps, 1080p video at up to 120fps, and has the same high-frame rate options as the RX100, like 960fps at slightly sub-HD quality. The camera can also capture in low-contrast S-Log3/S-Gamut3 video profiles for more professional-style footage.

Superzooms aren’t for everyone, but they make plenty of sense for people who want something a little more substantial than the compact RX100 without committing to a camera that requires multiple lenses. The price may a little bit higher for the RX10 this time around, but Sony’s effort to make the camera as silly fast as its other leading cameras might just make the cost worth it for some when it drops in October.

California Governor Gavin Newsom vetoes the state’s “BitLicense” law.

The bill, called the Digital Financial Assets Law, would establish a regulatory framework for companies that transact with cryptocurrency in the state, similar to New York’s BitLicense system. In a statement, Newsom says it’s “premature to lock a licensing structure” and that implementing such a program is a “costly undertaking:”

A more flexible approach is needed to ensure regulatory oversight can keep up with rapidly evolving technology and use cases, and is tailored with the proper tools to address trends and mitigate consumer harm.

Looking for something to do this weekend?

Why not hang out on the couch playing video games and watching TV. It’s a good time for it, with intriguing recent releases like Return to Monkey Island, Session: Skate Sim, and the Star Wars spinoff Andor. Or you could check out some of the new anime on Netflix, including Thermae Romae Novae (pictured below), which is my personal favorite time-traveling story about bathing.

If you’re using crash detection on the iPhone 14, invest in a really good phone mount.

Motorcycle owner Douglas Sonders has a cautionary tale in Jalopnik today about the iPhone 14’s new crash detection feature. He was riding his LiveWire One motorcycle down the West Side Highway at about 60 mph when he hit a bump, causing his iPhone 14 Pro Max to fly off its handlebar mount. Soon after, his girlfriend and parents received text messages that he had been in a horrible accident, causing several hours of panic. The phone even called the police, all because it fell off the handlebars. All thanks to crash detection.

Riding a motorcycle is very dangerous, and the last thing anyone needs is to think their loved one was in a horrible crash when they weren’t. This is obviously an edge case, but it makes me wonder what other sort of false positives we see as more phones adopt this technology.

Ford is running out of its own Blue Oval badges.

Running out of semiconductors is one thing, but running out of your own iconic nameplates is just downright brutal. The Wall Street Journal reports badge and nameplate shortages are impacting the automaker's popular F-series pickup lineup, delaying deliveries and causing general chaos.

Some executives are even proposing a 3D printing workaround, but they didn’t feel like the substitutes would clear the bar. All in all, it's been a dreadful summer of supply chain setbacks for Ford, leading the company to reorganize its org chart to bring some sort of relief.
