Sony A9 vs Sony A7R II

Image quality

Sony A9 comes with 24 MP effective pixels whereas Sony A7R II comes with massive 42 million effective pixels. Well, but the quality of the images totally depend on the kind of sensor used by the camera. Here Both the two cameras based on the large Full frame sensor of equal sizes (36 x 24mm), but Sony A9 implements stacked CMOS sensor with larger pixels area for super-fast readout and better light gathering ability, it also add front end LSI hardware and buffer memory associated with a sensor whereas Sony A7R II implements traditional BSI CMOS sensor. So due to advanced imaging technology used in Sony A9 we can expect much clear and sharper images from A7R II, even in lowlight. Luckily, the users of Sony A7R II will get the large print of the subjects compared to A9 because the camera employs higher resolution.

AF system

The AF system employed by Sony A9 is unassailable. 693 AF points, which was totally unheard before is now made available to get used with Sony A9. On the other hand, 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. Now with the announcement of Sony A9, they broke their own record once again and surprised the world with their innovative tech.

Well, both the two cameras are based on hybrid AF system (Contrast as well as Phase detect AF system inside the core), but the 693 on-sensor phase detection points over 399 of A7R II erases all the differences and makes Sony A9 a camera that covers 93% of the frame  with 60 AF/AE tracking calculations per second- most wider coverage offered by any camera of the current time. etc.


Sony A9 is superior in every place and in ISO it gently beats Sony A7R II, offering you highest sensitivity range of 204800, plus its LSI hardware inside the core, ensuring you very clean and consistent shooting in lowlight and captures images with minimal noise.

Shutter speed

Sony A9 avails faster shutter speed 1/32000 s electronic shutter to minimizes the “rolling shutter” effect that  are commonly experienced with fast moving subjects. As a result Sony A9 will be able to capture sharp, crystal clear images with a wide open aperture. On the other hand, Sony A7R II avails the mechanical shutter of 1/8000 that may not be as superior as of Sony A9.

Continuous shooting speed

So many actions and activities are done on the field and if you have the camera with lesser frame rates you can’t capture all the actions, but this is not with the case of E-Mount Sony A9. Sony A9 features frame rates of 20FPS helps you capture much more activities and actions of the desired subjects and reduces the chance for action to blur in any single frame, allowing camera to capture sharper images compared to Sony A7R II that comes with only 5FPS only.


Here also Sony A9 snatches the point from Sony A7R II by allowing you capture 650 shots at a single time charge, whereas Sony A7R II battery will drain up just by taking 290 shots only.


Sony A9 is massive E-Mount camera that astonishingly surpasses many high-end DSLR cameras of the present time, featuring almost everything that a professional shooter needs, such as incredible 693 AF points, Continuous shooting speed with no blackout etc. And if you are in mind to buy one single camera between these two and also you have no problem to extend your budget then we must say Sony A9 is the camera you should pick.
