Sony Alpha 7R II vs. Nikon D810 Specification Comparison Table.
Sensor – The Sony A7R II has more resolution compare to Nikon D810 so it will produce a sharp, clear and more accurately printouts with good quality.
The sensor design of Sony A7R II improves low-light operation and speeds up data throughout, it enables fast high-resolution stills and UHD 4K video recording. Its BIONZ X image processor helps to produce the images at sensitivities up to ISO 102,400 at a continuous 5 fps shooting rate.
The high resolution of Nikon D810 provides detailed playback viewing and live view capture with color balance and brightness control. A split screen display zoom for still shooting lets you compare two enlarged points in the image for sharpness and exposure.
Image Stabilization:- The presence of Five-axis SteadyShot INSIDE image stabilization in Sony A7R II offer compensation for vertical, horizontal, pitch, yaw, and roll movements. But there is absent of image stabilization in Nikon D810.
Image processor:- The Sony A7R II has used the world’s first full-frame 42.4-megapixel Exmor R back-illuminated structure CMOS sensor. The sensor is designed in such a way that it improves low-light operation as well as speeds up data and its high resolution also support UHD 4K video recording. Its BIONZ X image processor support to produce the images at sensitivities up to ISO 102,400 with continuous shooting rate of 5fps.
Nikon D810 has EXPEED 4 processor managed to reduce the production of noise due to its low ISO range. It not only support 1080p video capture at 60 fps but also it is enable to 1200 still shots and 40 minutes of video recording after the battery charged once time .
AF System:- The AF System of Sony A7R II uses 399 phase-detect points and 25 contrast-detect points for a speedy Fast Hybrid AF system which will offer extremely accurate tracking.
Sony A7R II has 399 phase-detect points and 25 contrast-detect points and hence it is the world’s first full frame mirrorless camera which uses such higher AF points with 45% coverage along with 25 contrast-detect AF points for the improvement in the speed , accuracy and tracking performance of the system.
It can shoot continuous frames of 40MP @ 5fps with tracking, continuously upto 24 frames while shooting in JPEG L format.
It also includes an important property that the AF system of Sony becomes active during shooting either still photography with viewfinder using live view mode.
But Nikon D810 has advanced Multi-CAM 3500FX autofocus sensor which offers 51 AF points with 15 cross-type sensors and its Group Area AF enables five AF sensors which is used as one group. Such type of system is useful when the users feels problem to track the shooting subjects by one AF point due to lighting conditions.
Nikon D810 can capture 5 fps Shooting at Full Resolution, and the users can capture 57 Large fine JPEG with Phase AF tracking,.
When we are using the view finder of the camera then only that period the AF point of the Nikon D810 DSLR camera remains active , otherwise on capturing still images with live view mode or while recording videos the phase AF system gets disabled and Contrast AF system gets active which slows down the AF speed of the camera.
Hence Sony comes with more advanced AF system.
ISO Range:- The ISO range will also play an important role in the production of sharp and correct image. The higher the ISO the perfect image will be created.
The images with small pixel size have high resolution and after lowering the pixels sizes the sensitivity of the camera also goes down and hence it affect the ISO range of the camera which is not in the favor of image quality.
The native ISO sensitivity range of Nikon D810 starts from 64 to 12,800 and can be expanded upto 32 to 51,200, but Sony A7R II camera with native ISO range of 100-25600 and extended ISO range of 50-102400, which is much higher than Nikon D810.
We know the higher ISO of Sony A7R II makes its image sensor more sensitive and hence it produces sharp images in less light. In this regard it is confirmed that Sony A7R II camera has the capability of shooting low-light images as well as it can also capture the images with high resolution compare to Nikon D810.
Shutter:- The Sony A7R II has used the reduced-vibration shutter and also added it with a Silent Shutter mode which reduced the mechanical vibrations up to 50%. Its top shutter speed is 1/8000 and the mechanical shutter inside the camera has been tested to last for 500,000 cycles.
On the other hand Nikon D810 based on Electronic & Mechanical shutter, electronic front-curtain shutter which reduces the risk of blur in even subtle details by minimizing internal vibrations during exposure. The Nikon D810 top shutter is same as Sony A7R II and the mechanical shutter inside the camera has been tested to last for 200,000 cycles.
Both camera uses Hybrid shutter technology.
Video – The Sony A7R II is the first full-frame camera to offer internal UHD 4K video recording at 30 or 24 fps with the support of either the full-frame sensor or the Super 35 format which uses oversampling with full pixel readout and no pixel binning.
The Nikon D810 offers a Fulll HD Video mode and contrast based AF system. Hence far behind
The Sony A7R II can capture 4K Videos and records it internally, 35 format which uses oversampling with full pixel readout and no pixel binning, while recording the Video the phase AF system is fully active, thanks to the 399 phase-detection AF points present in the Fast Hybrid AF system, you get blazing fast AF speed without any focus hunting issue like a traditional contrast detect sensor have.
The Nikon D810 is limited to Fulll HD Video mode and contrast based AF system.
Wireless – The Nikon D810 connectivity is possible with optional WT-5A Wireless Transmitter in combination with the optional UT-1 Communications Unit. Sony A7R II camera features built-in wireless and NFC connectivity, with WiFi you can share your images with mobile devices directly, and NFC allows for one-touch connection between the camera and compatible mobile devices
Sony A7R II features more advance wireless connectivity option.
High ISO Test Between Sony A7R II vs. Nikon D810
Verdict: Sony A7R II is clear winner since the cameras features more resolution, more ISO range, advance Phase detect AF system, a option to record high quality 4K videos and can also connect wirelessly with smartphone.
