Thank you both, Robert and K.
And yes, you're right, there is something messed up between Camera Raw and Nex-7 settings, but I cannot enterely grap what is wrong
-First of all, Robert, I've had the Nex-7 settings to 16:9 images format. Setting the Nex-7 to 3:2 format all Camera Raw sofware show the 6000 x 4000 image which is expected and viewed at the display
Obviously, a 16:9 image is a transversal cropped one from the entire image at the sensor. Looking the images with the Preview app I realized that the original file is 6000 x 4000, and not a 6000 x 3376 like a 16:9 image.
Thus, there is still a problem. Setted up the cam to 16:9 aspect ratio, what you see at the display and through the viewfinder in the Nex-7 doesn't fit to what you get at RAW softwares as the 16:9 image that you saw and shoot. One solution, recover the whole image with any other software than Camera Raw. My preferred, for the moment yet, is to use the Nex-7 just in 3:2 format, which is in my opinion a lack.
Even Sony advice of a fun feature: you will cannot visualize at the display the whole images shoot in 16:9 aspect ratio...!!!
-K, I've had tried that way to reset the Camera Raw Deafaults, and did it again when read you, in the hope of it works, but nothing noticeable occurred. There is a lot to talk about, I haven't could find the way to change Camera RAW configuration or settings. I don't know if we really can do it, farer than overall adjusts...
There is a messed up settings at the Nex-7, like Mr Reichmann noted in his reviews.
From my two weeks of use of what at first look is a great camera, I hope that Sony could fix these issues with new firmwares, and add some other features, like 4:3 and 16:9 formats that fit with what you see and what you get...
and could Sony add a 50 ISO feature in a new firmware or is it technically impossible?
Thanks you all for this great site and forum, and please sorry my bizarre english
