Moving to an even higher resolution realm, the Sony a7R IVA continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP sensor along with faster processing, improved AF performance, and a more well-rounded feature-set for both high-end photo and video applications.
 
Featuring a back-illuminated design, the newly designed full-frame 61MP Exmor R CMOS sensor offers a mixture of incredible resolution with high clarity, low noise, and a wide 15-stop dynamic range. The sensor's structure promotes impressive image quality and a copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400.
 
The BIONZ X engine's high-speed image processing enables fast continuous shooting, 4K video recording, and advanced AF tracking. The quick processing also helps to reduce rolling shutter and other motion distortions for clean rendering of moving subjects.

In terms of shooting speeds, the sensor and processor enable up to 10 fps shooting, at full resolution, for up to 68 consecutive frames, with full-time AF/AE.
