Comment(by Quozl):

 status:
  * have ten samples,
  * have camera assembly specification, Suyin CM031B-SE02 rev 0.1,
  * have CMOS Sensor datasheet, SETi SIV121C.

 assessment:
  * sensor registers are different,
  * device can be identified over bus,

 comparison:
 || ||siv120d||siv121c||
 ||adc||pipeline integrated||column parallel||
 ||subsampling mode||VGA QVGA QQVGA||VGA QVGA QQVGA CIF QCIF QQCIF HV||
 ||image area, diagonal||1794.3 um||1809.3 um||
 ||sensitivity||1.3V/Lux-Sec||0.71V/Lux-Sec||
 ||maximum frame rate||30fps @ VGA, 27 MHz MCLK||30fps @ VGA, 24 MHz MCLK||
 ||dynamic range||54 dB||60 dB||
 ||signal to noise ratio||38 dB||37 dB||
 ||power consumption||55mW||80mW||
 ||standby||30uA||60uA||

  * should do better at low light levels,
  * draws more power.
