Sony a7SII vs Sony a7S vs Sony a7RII Specs & Size Comparison

Here is a quick specs and size comparison for the Sony a7SII, Sony a7S and Sony a7RII. You can take a look at the key differences between the three Sony full frame E-mount mirrorless cameras.

Sony a7SII ($2,999): 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.

Sony a7S ($2,498): The innovative a7S camera features a newly developed, 12.2 effective megapixel 35mm Exmor® CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 4096002 with unprecedented dynamic range and low noise. The a7S is also the world’s first camera to utilize the entire width of a full-frame image sensor in 4K video acquisition, and does this without cropping or line skipping as it can read and process data from every one of the sensor’s pixels. This allows 4K video shooters to utilize all of the artistic and creative benefits provided by the unique sensor.

Sony a7RII ($3,198): The Sony a7RII 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. Working with the BIONZ X image processor, these images can be produced at sensitivities up to ISO 102,400 and at a continuous 5 fps shooting rate. Five-axis SteadyShot INSIDE image stabilization has also been implemented, compensating for vertical, horizontal, pitch, yaw, and roll movements.
