What is the sensor being used in the C905. There are three rumors going around.
1. Samsung CMOS sensor similar to the i8510 INNOV8 but poorer in quality.
2. Sony CCD sensor ICX636/646. (PDF Spec Sheet)
3. Sony EXMOR CMOS
"The C905 comes with an Exmor CMOS image sensor and its unique Column-Parallel A/D Conversion Technique and dual noise reduction with even higher sensitivity and lower noise. The development of a image sensor that combine ease-of-use, advanced image quality and cutting-edge pixel miniaturization and with a focal length of 5.91mm."
The last one makes most sense since it is similar to the sensor used in the Japanese SO905iCS except larger.
