Sensor: 14.6 to 15 MP new Samsung sensor - debugged version of the old one
used in the K20D: Less Noisy, More Functions for LV and Movie (okay啦）
Metering System: New 77-segment 7x11 (Seven Eleven? ;->) equally divided
metering system - more advanced (总比以前的好，不过算法能做好不能做好谁知道?)
AF System: Still SAFOX VIII 11-point AF hardware with tweaked AF software
algorithms and should respond faster and better at low light
（这个拭目以待，估计比canon/nikon的对焦系统还是有距离）
WB System: New More Advanced and Accurate Auto WB system
