Sony adds super speed to what's probably the best point-and-shoot on the market, the RX100 IV
While most manufacturers have largely ignored the point-and-shoot category, Sony goes against the grain with the stellar, speedy RX100 IV.

Hey! You should know that Sony has released a newer version of this product: the Sony RX100 V.

In a market where point-and-shoot cameras are largely ignored, Sony has introduced a wealth of new technology in their top-of-the-line compact, the Sony RX100 IV. The previous versions have all impressed with the large sensor and bright lens, making small improvements every year with things like a pop-up viewfinder. But this year, the updates are huge--the sensor has been redesigned, the speed gets a big step up, and the video gets bumped up to 4K. And we didn't even have much complaints about the last model.

The sensor is still that large 1" size, but it's now stacked. It's a design popular in smartphones because it allows the technology to fit in a smaller space. The stacked design isn't just about space, however--it's what's allowing for the enhanced speed.

The previous model's 10 fps burst speed has been pushed even further to 16 fps. But what's even more impressive is this camera's shutter speed tops out at 1/32,000, where a lot of point-and-shoots are lucky to see 1/8,000. That's with their electronic shutter, the mechanical one stops at 1/2,000. That shouldn't be a problem though; Sony says their Anti-Distortion Shutter prevents image distortion. While we'll wait to test that claim, the fast shutter speed should be excellent for capturing action (provided there's enough light) as well as allowing for more flexibility in extremely bright lighting conditions.

That stacked sensor also leads to 4K video. It's limited to five minute clips because of the large file sizes, but point-and-shoots aren't often used for long videos anyway and 1080p video is available when longer shots are necessary. Slow motion shots are big here too, with motion as slow as 40x.

Along with all the new tech, Sony is building on what was already a solid camera. The large sensor and bright f/1.8-2.8 lens is an excellent combination for low light photography or dramatic depth of field. There's both an electronic viewfinder and a tilting LCD screen. A control ring around the lens makes those manual modes a bit easier to use. Nice extras like focus peaking and wi-fi are still there as well.

The only things we see (so far) that Sony wasn't able to cram into a compact camera is a big zoom and an affordable price. There's a 2.9x optical zoom to help with composition some, but it's not much. And of course all of those innovations don't come cheap--the Sony RX100 IV will run you nearly a grand. Sure, it's probably the best compact camera out there, but you could spend that money on a DSLR with an even larger sensor (though probably not as much speed). It's a luxury item for sure, but one that appears to perform up to its price tag.

The Sony RX100 IV will hit shelves in July, 2015.

Sony Reviews

Sony has been at the forefront of the market for consumer electronics for the past 30 years by offering innovative imaging products in response to changes in the market. Sony has made cameras that are ideal for casual users, hobbyists, and professional photographers through their dedication to implementing the most current technology with a sleek and minimal style, resulting in an end result of the highest quality.

Sony was the first to put a full-frame sensor inside of a mirrorless camera, the A7 and A7R, and a little later, the A7S. While the first-of-its-kind cameras aren't without flaws, Sony executed their ideas fairly well and made some pretty solid cameras to start the new line.

Speaking of first-of-its kind, Sony also designed a “camera-without-a-camera,” the QX10 and QX100. These cameras have a sensor and lens, but no operating system—instead, consumers use their smartphone via wi-fi or NFC to operate the camera. While the cameras certainly have flaws (mainly in the slow response due to operating through wi-fi), we still have to applaud Sony for the way they've responded to the rise in smartphone photography (plus the cameras have actually sold remarkably well).

Sony has also been highly successful with the RX compact camera line that began with the RX100, a compact camera with a 1” sensor, excellent image quality and full manual modes. The camera has since seen some solid updates, and remains a good option. Sony also added the RX10, a camera with a 1” sensor but instead of focusing on compact size, adds a much bigger zoom.

While their focus is on more advanced models, it’s usually a pretty safe bet to pick up a Sony compact, even a budget priced one, and still get a lot of bang for your buck. We're also big fans of Sony's designs, making their cameras easy to use and adjust, like the HX400 that has an automatic sensor on the electronic viewfinder as well as a control ring around the lens.
