Have a look at the detail comparison of these two cameras: Nikon D850 vs Sony A7R II!

Image quality

Interestingly, both use back-side illuminated (BSI) full-frame image sensor. Basically, the image quality of a camera depends on the type of sensor used by a camera. Here both the two cameras use BSI Full-Frame sensors so we expect to see nearly similar quality of images. But Nikon doesn’t have low pass filter at the core, letting the users to grab large details of the subjects even in lowlight. On the other hand, Nikon D850 can give you the large prints of the subjects since it has higher resolution (45.7 MP vs 42 MP).

AF system

Sony A7R II’s AF system is one of the key reasons that make it a astonishing professional camera. Nikon D850, on the other hand, implements Multi-CAM 20K AF module that dramatically improves AF performance while shooting subjects. But the problem is the Multi-CAM 20K module is active only when you are using viewfinder of Nikon D5 and once you switched to live view mode or you record a video Nikon D5 uses contrast detect AF system and entire AF system gets slow and sluggish.

Sony A7R II, On the other side, the AF system used by Sony A7R II was not short of any astounding (399 + 25 AF points). Sony created records when they first unveiled it and won the crown for being the best AF system in any camera. 399 AF points can cover 45% of the total image area, which is much more than 153 AF points of Nikon D850.

Image stabilization

Look at the table, Nikon D850 doesn’t have Image stabilization mechanism inside, which is highly essential to compensate for the appearance of camera shakes. On the other hand, Sony A7R II implements 5-axis images stabilization corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) usually occur while shooting with a telephoto lens, shift shake (X and Y axes) increases as magnification increases, and rotational shake (roll) that often affects video recording. With 5-axis I.S system A7R II can produce crisp and blur free images even while shooting in lowight.

Continuous Shooting speed

9fps vs 5fps   Sony A7R II is lagging behind in the race since it offers only 5fps shooting speed. On the other hand, Nikon D850 offers 9fps that superbly captures the actions and activities of the desired subjects.


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


Nikon D850 lets you capture around 1840 shots at a time, whereas Sony A7R II allows capture only 290 shots at a time.


Both are highly outstanding camera. One is DSLR and other is Mirrorlress camera with marvelous features. You simply can’t say one as better camera from the specification comparison, but still Nikon D850 earns some good bucks for its sensational AF system and remarkable High resolution image sensor. On the other hand, A7R II captures professionals through its sharp and bright overall performance, such as its 399 AF points – Simply amazing! But we still recommend to go with Nikon since the new camera comes with advanced and upgraded core specs that can give you colorful result in imaging performance.

Decision is yours!
