Full-Frame Mirrorless Monsters Comparison: Sony a7RII vs a7SII
In 2015, Sony released two full frame mirrorless monsters: Sony a7RII and Sony a7SII. Both are amazing cameras, but if we put them together: Sony a7RII vs a7SII, what’s the result? That would be interesting!
Sony A7RII ($3,198 at Amazon, B&H, Adorama): The hot Sony A7RII mirrorless camera features the world’s first full-frame 42.4-megapixel Exmor R back-illuminated structure CMOS sensor. This sensor design both improves low-light operation and speeds up data throughout, enabling fast high-resolution stills and UHD 4K video recording. The new Sony a7RII is a true Game-changer, and DPReview said “Sony’s Alpha 7R II breaks a lot of new ground in terms of photographic technology “. And lots of news said the new Sony a7RII is amazing and it is the killer of Canon EOS 5DS R and it can even beat the Nikon D810.
Sony A7SII ($2,998 at Amazon, B&H, Adorama): Sony A7SII is the new “low-light monster” camera. Revolving around a full-frame 12.2MP Exmor CMOS sensor, the a7SII is capable of internal UHD 4K recording at 30 fps with full pixel readout as well as 1080p recording at up to 120 fps, all in the XAVC S format. Benefitting recording versatility, the BIONZ X image processor also pairs with the sensor to enable expanded sensitivity to ISO 409600 along with fast intelligent autofocus with low-light sensitivity to -4 EV. Further enabling working in difficult lighting conditions, 5-axis SteadyShot INSIDE image stabilization compensates for vertical, horizontal, pitch, yaw, and roll camera movements for sharper, smoother handheld recording.

Mirrorlessons posted the Sony a7RII va a7SII comparison and he writes:
If low-light situations are what you find yourself encountering on a daily basis, then the A7s II can become a better option if you know you will frequently use it between 6400 and 51200 ISO. If you work with Sony cameras already, it can also become an excellent second body for stills in poor light.
My opinion of these two cameras isn’t the same for video. While the A7r II has excellent 4K capabilities, the A7s II was born to shoot movies above all else and the footage I recorded with it is among the most beautiful I’ve seen from a mirrorless camera. More than for photographers, this camera is a great tool for filmmakers. However if your video needs are not that desperate, the quality of the A7r II is more than enough.
