Sony's "α7R VI" uses a stacked sensor to improve not only image quality but also mobility: Kei Ogikubo's Digital Camera Review Plus (Page 1/5)

Sony unveiled the α7R VI, the sixth-generation high-resolution mirrorless camera in the α7R series.

It features about 66.8 megapixels, the first stacked CMOS sensor in the lineup, and a new BIONZ XR2 processor.

The upgrades deliver faster readout, better electronic-shutter performance, and improved subject detection and continuous shooting.

Sony aims to make the α7R line more practical for fast action and advanced autofocus work while maintaining image quality.
