Sony announces development of 35mm CMOS sensor

After Canon and Nikon Sony finally announced a 35mm full size sensor (24mm x 36mm). The new 24.8 megapixel sensor promises a high dynamic range, low noise and fast processing. This new chip promises to output all pixels at 6.3 fps thanks to its “Column-Parallel A/D Conversion Technique” whereby each column of photosites is given its own Analogue to 12 bit Digital Converter. Sony announced to begin with mass production within this year, which means that we might see the next generation of the alpha series of Sony with this new sensor.

Major features

1. High picture quality in 35mm full size image sensor with 24.81M effective pixels
2. “Column-Parallel A/D Conversion method” achieves high S/N and high-speed imaging
3. High-speed digital output （12 channel parallel LVDS output）
   • CDS/PGA (24dB) Circuit （PGA: Programmable Gain Amplifier）
   • 12bit-AD Converter on chip
   • Diversified readout mode
   • All-pixel scan mode 6.3 frame/s (12bit)
   • Window readout
