I sent back for refund two NX70s. I had hoped the first one was defective. It was not, the problem is a design flaw. The NX70 is based on the consumer CX700V optics and engine. There are major problems with chromatic aberration and poor focus in different areas of the image. My CX550V had a better image!
I am bitterly disappointed. The NX70 on paper was perfect.
I cannot live with crappy image quality!
Some examples of the problem here:

Now I am looking at the NX5, but I worry about the back-focus problem ...
