The Sony a7R III keeps the resolution, adds impressive speed
Sony is stepping up their high resolution mirrorless camera with some high speed to match.
By Digital Admin, Last updated on: 12/20/2017

The Sony a7R III is a happy medium between the super-fast a9 and the older a7 II, mixing high resolution with a fast burst speed. The camera has the same resolution as the predessor, but offers a significant increase in speed along with sharing a few other characteristics with the pricier a9.

The a7R III uses a 42.4 megapixel sensor, that's the same resolution as the predessesor, but while the resolution is the same, the sensor uses an on-chip microchip for handling those large files faster. Add in an updated processor and the A7R moves from 5 fps to 10 fps in the III. Doubling the speed also requires an even faster autofocus, and Sony says the a7R III offers that with 425 autofocus points on teh hybrid system.

Like the predessesor, the Sony a7R III uses a five-axis sensor shift stabilization system, allowing photographers to shoot handehld at slower shutter speeds. The same 4K, 30 fps video mode is also included.

The weather-sealed body also hides a few other improvements -- the battery life has more than doubled at a 530 shot rating. Sony also doubled up on the SD card slots, a plus since taking big files even faster will fill up that card faster. Much of the rest of the body remains similar to the previous option, including a tilting LCD screen.

The Sony a7R III mixes high resolution files with big speed. The closest competitor with that mix is the Nikon D850, which isn't quite so fast but has a longer battery life as a DSLR. The a7R III has a similar price as well, listing at about $3,200, significantly lower than the speedier, but lower resolution Sony a9.

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.
