I agree with mayurgogoi
Edmond Leung: The dynamic range of K-30 looks bad when compared with others.
Last time I looked (yesterday) Dx0Mark had not evaluated the K-30 yet. Has that changed? *LOOKS* Nope, all they have is specs. K-30 is 12 bit and K-5 is 14 bit. No way is the K-30 going to surpass the K-5.
peevee1: For some reason K-30 is not quite to the standard of K-5, although the sensor is apparently the same.
It is a similar sensor, although apparently not the SAME sensor as the K-5. Also, the K-30 only does 12-bit RAW as opposed to the K-5 with 14-bit RAW. More data to work with, which you see especially in the superior dynamic range of the K-5.
