Das gestackte am Sensor ist offenbar eine andere Schicht als bei der A II, was erklärt dass die Auslesegeschwindigkeit doch noch deutlich niedriger ist. Die Technologie ist also nicht ganz vergleichbar. Ich zitiere mal Dpreview:
Zitat:
The heart of the a7R VI is a new, 66.8MP Stacked CMOS sensor. Unlike the sensors in Sony's previous high-end bodies, the second layer of the sensor isn't DRAM memory, to buffer the data coming off the sensor, instead it's described as a processing layer.
Noticeably, this means that the full sensor readout speed is slower than in the likes of the sports-focused a1 II; instead, it's able to combine the output of its two conversion gain modes, using both the low noise and high capacity modes to give wider dynamic range.
The net result is a sensor that's much faster than its predecessor (around 5.6x quicker than the a7R V, according to Sony) but with better dynamic range. This should significantly expand the range of photographic situations the a7R VI can lend itself to, without a negative impact on the areas where the a7R V already performed well.
The faster sensor allows the camera to shoot bursts at up to 30 frames per second, using its electronic shutter. This is a huge step forward from its predecessor, which took around 100ms (1/10th sec) to read its sensor in e-shutter mode.
