Btw, is it really cheap? Just compare it with the similar offers from Canon and Nikon! One thing is for sure anyway, the original set price of $249 is just ridiculous!
2. DC Watch has reviewed the DA560, with various full samples posted, taken with a K-5IIs:

(in Japanese)
I am really not impressed with the IQ of this combo. The colour rendition is terrible. Images lack contrast. The broken pixel "sharpness" of the K-5IIs images also look rather odd to my eyes.
