Sony A7R III vs Nikon D850

Sony A7R III is monster camera in terms of its resolution and AF system and next it includes a pretty spectacular array of evolutionary improvements. On the other hand, Nikon D850 is also a megapixel hero but Sony A7R III is quite big camera that gives the newly announced and one of the High-End DSLRs from Nikon a tight round of fight in specification comparison. Sony A7R III is not a complete replica to Sony A9 (Sony’s flagship) but designed based on its incredible specifications. Meanwhile, Nikon D850 is really a big DSLR camera that carries a few specs of Nikon D5.

Well, let’s dive deeper into the specification comparison between Sony A7R III vs Nikon D850!

Image quality

The difference in the image quality will be normal since both are just the beasts in terms of resolution. One side, Sony A7R III employs 42.4MP high-resolution, back-illuminated Exmor R CMOS image sensor utilizes a gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s seal glass that incredibly captures light to produce Ultra-sharp and stunning detail images. Nikon D850, on the other hand, 45.7MP BSI CMOS sensor will able to capture tack sharp images with exceptional details. However, due to large number of effective pixels, Nikon D850 can give us bigger print of the subjects compared to Sony A7R III. Though both have no low pass filter that ensure duo can capture premium shots even in lowlight since elimination of low pass filter helps get large detail of the subjects.

AF system

Really Sony A7R III stunned us with its Remarkable AF system! A7R III is comprised of 399 focal-plane phase-detection AF points that cover approximately 68% of the image area in both the horizontal and vertical directions. And 400 more Contrast AF points compared to its predecessor ( A7R II has 25 AF points) that ultimately increases the AF acquisition twice the faster than A7R II. Nikon D850, in contrast, comes with Multi-CAM 20K 153-point AF system as of Nikon D5. But in practical, Sony is the winning horse of the race.

 Image stabilization

Thankfully, Sony A7R III comes with vibration reduction mechanism inside that features the excellent 5-axis I.S that effectively controls the camera shakes and offers crisp, sharp and blur free images, which at a time very useful during shooting handheld. This innovative 5- axis system provides a shutter speed advantage of 5 steps, letting the users to realize the full resolving power of the sensor even in the challenging shooting situation, such as in lowlight. On the other hand, Nikon D850 doesn’t incorporate I.S mechanism so one needs a lens with optical image stabilization so get extraordinary images.

Continuous shooting speed

The Sony A7R III offers higher frame rates of 10 fps, ensuring that camera can capture much more of the action each second, reducing the opportunity for action to blur. This results in producing sharper images in any kind of shooting (basically used in capturing the sports action of the intended players or subjects). Meanwhile, Nikon D850 offers continuous drive of 9fps of continuous frame rates just 1 fps lesser than A7R III.


A large 3.2″ 2.359m-dot LCD screen is available for bright, clear, and vivid image playback and live view shooting.


Since Nikon D850 is DSLR and its battery is sturdy that lets you capture around 1800 shots at a time, while A7R III lets you capture only 650 shots.


Sony A7R III gently supersedes Sony A7R II and in contrast with Nikon D850, the Sony A7R III left a mark. Its AF system are just tremendous plus it engineers 5-axis I.S. To be true, A7R III and D850 comes to a nail biting end, but both are professional level cameras and probably in AF terms, Nikon D850 looks inferior but it covers different areas incredibly. So you have give yourself a solid timing of decision so that you can invest on one camera between these two. But before that you can wait for practical comparison to invest on.
