The Sony RX10 IV mixes big zoom with big speed
Keeping the same solid lens and sensor, the Sony RX10 IV has even more speed than the predecessor.
By Hillary Grigonis, Last updated on: 10/20/2017

The Sony RX10 IV keeps the same body style and sensor and lens combo that made the previous version so successful -- but steps up with some serious speed improvements. The combination of the big zoom lens, compact body style and fast speed makes the Sony RX10 IV excellent for a number of different shoots, including travel and sports.

At the heart of the camera is the same 20.1 megapixel one-inch sensor found in the RX10 III. The sensor is larger than those found in cheaper travel zoom cameras and that's paired with a 25x zoom lens, a good range for a sensor of this size. The lens also has a wide f/2.8 to f/4 aperture range that's brighter than most as well.

Where the IV begins to differ from the III is speed. The RX10 IV boasts category-leading, .03 second autofocus, according to Sony and thanks to a 315 point phase detection autofocus system. Paired with an impressive 24 fps burst and the RX10 IV should be excellent for action. The shutter speed also has an impressive 1/32000 limit and uses an anti-distortion shutter to prevent distorting moving subjects.

Video should also be excellent with a hybrid video autofocus system and 4K resolution. Slow motion is available at lower resolutions, to slow down that action up to 40x.

The body style remains similar to others in the RX10 series with a DSLR-like control scheme and size, despite the fixed lens. While larger than a compact camera, the camera is smaller than a DSLR if it was paired with a lens with similar zoom capabilities. New to the series, the touchscreen on the back of the camera also tilts.

The Sony RX10 IV boasts impressive specifications  -- but a high price to go with it, retailing for around $1,700. While the RX10 IV boasts several industry leading specifications, the Panasonic FZ2500 should also be closely compared for its lower price point.

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.
