No compromised in the sharpness since both the two cameras house the powerful 35mm full-frame (35.9 x 24.0mm) sensors with 42.4MP of resolution and a back-illuminated structure to attend the wide sensitivity range of 100 to 102,400 ISO and low-noise performance. However, both don’t have low pass filter which means even in lowlight the camera will be able to capture detail images of the subjects.

AF system

Not a big difference in the AF system of these two siblings, but A7R III, being new to the market offers 400 more contrast AF points compared to the A7R II (Total 425 AF points). However, both have 399 phase detection AF points, which are great for comprehensive AF coverage that work together with  their respective contrast AF points, allowing camera to achieve super fast focus response (Sony A7R III has 425 AF points, Sony A7R II has 25 AF points).

Continuous shooting speed

If you take a look at the entire table you can see that A7R III retains most of its predecessor’s specifications. However, A7R III does quite well enough in terms of burst speed: 10 fps vs 5 fps.  10 Fps allows the camera to capture the action of the subjects very quickly.  Sony A7R II is lagging behind in the race since it offers only 5fps shooting speed.

Battery Life

Maximum 650 shots at a time you can take with Sony A7R III, whereas Sony A7R ii allows you take 290 shots only.


Both A7R III as well as A7R II comes with almost similar specifications, but somewhere due to maximum burst rate and and AF points Sony A7R III raises strong. However, if you want a slim upgrade from Sony A7R II then Sony A7R III is phenomenal!
