What resolution is the a1?
The a1 is equipped with a newly developed full-frame 50.1MP Exmor RS stacked CMOS sensor. This should provide users with outstanding detail and dynamic range.
What is a “stacked” sensor?
Sony’s Exmor RS, or stacked, sensor design uses a combination of technologies to improve low-light performance and readout speeds. It uses a back-illuminated design to ensure each photosite (pixel) receives as much light as possible and adds a DRAM memory chip mounted on the rear of the sensor for ultra-fast off-loading of image data. The on-chip memory increases shooting speeds, reduces the impact of rolling shutter, and allows for faster video frame rates.
