Just see this blog article and I have to agree with most of the opinions and comments of that guy who has eagle eyes!

Actually, I had similar observations and comments when the DPR K-7 review is out. I have to say that DPR staff and crew have done great jobs for their recent reviews, in which their comments and conclusions drawn and made are really quite different from what their own testing pictures would say and tell! Well Done, Phil and guys! :-D
