We can clearly see the minor difference in the design part of both the camera, the size of both the camera is somehow similar.
The recently announced Sony A7R II camera features newly developed Hybrid CMOS AF sensor fabricated with 399 Phase AF points that let you achieve focus quickly even when used with third party lenses…Take a look at the specification of review of both the camera,
Sony Alpha 7R II vs. Sony Alpha 7R Specification Comparison Table.
Let’s start with the resolution of both the camera, there is no much difference in the resolution between them but SonyA7R II has comparatively a bit more resolution than its predecessor Sony A7R.
Sony A7R II is based on the world’s first back-illuminated full-frame sensor 42.4 MP Exmor R BSI CMOS Sensor and No optical low pass filter inside it gives you vast amounts of details when used with recommended set of lenses. Sony A7R is limited to 36.4MP Exmor CMOS Sensor with No Optical Low Pass Filter .
Both the cameras have used the similar Exmor R CMOS sensor but Sony A7R II has followed the BSI (back-illuminated) technology which increased the ISO range from 25600 to 102400 . Hence the presence of BSI technology and bit high resolution in Sony A7R II makes it superior to Sony A7R.
Sony A7R II is packed with a 5-axis SteadyShot INSIDE image stabilization system. Such type of system provides the solution for five types of camera shake during shooting of still images and videos. Due to the presence of this system the users can use any lens, even adapted lenses, for imagery without facing any problems due to camera shake. This system offers about 4.5 stops of shutter speed during shooting different varieties of subjects.
It’s all the 5 axis of stabilization system runs every time, even if the users used with third –party lenses and adapters.
There is no presence of Image Stabilisation in Sony A7R.
Hence presence of Image Stabilization in Sony A7R II makes it superior to Sony A7R because it compensates in real time for shaking and vibrating while recording the subjects.
AF System: –
Sony a7RII uses Fast Hybrid AF with 399 Phase-Detect Points with 45% coverage along with 25 contrast-detect AF points, due to this it became the world’s first full frame mirrorless camera with highest AF points. The Hybrid AF sensor and Bionz X image processor increases the speed, accuracy and tracking performance of the system. It offers faster readout which is due to the presence of the back-illuminated sensor structure and it also allows for tracking while shooting at the top continuous shooting rate of 5 fps. It also allows Lock-on AF tracking that release more information from the scene which helps in the improvement of accurate and stable imaginary.
But Sony A7R uses new Fast Intelligent AF system which has only 25 contrasts-detect AF points which is optimized for the full-frame sensor including flexible spot focus areas in addition to multipoint, center-weighted, and zone focusing.
Due to the presence of advanced AF System and more AF points in Sony A7RII, it make it totally different and superior to its predecessor.
The Sony A7R II has more ISO Range of 50-102400 due to the presence of BSI technology, which helps it to capture the object in dim light, provide high level of low-noise performance and dynamic range, which makes it superior to its predecessor Sony A7R and hence due to low ISO range Sony A7R provides low image quality.
The a7RII is the first full-frame camera to offer internal UHD 4K video recording at 30 or 24 fps, Sony A7R was limited to 4K recording only.
Additionally, the A7R II camera can record videos by using 399 Phase AF points, its a great advantage that a you can use fast Phase detect AF instead of slow and sluggish contrast detect AF.
Other difference – The other major difference we have spotted is price, the Sony A7R available at $1,898.00 and the Sony A7R II camera available at $3,198.00.
Verdict: The Sony A7R II specification is far better than its predecessor, you get high sensitivity CMOS sensor with 399 Hybrid Phase AF points and a option to record 4K videos.
