I still don´t have a clear picture of what is going on, but I came to a few conclusions after reviewing the pictures and doing some additional tests today:- Most of the problems happened with the Nikon 17-35mm f2.8. Since this is an old lens and has recently undergone service after a fall, I guess something is still messed up with it; I will do further tests to make sure;- Still, some problems happened with the Nikon 70-200 f2.8 VR. However, I noticed that in all pictures taken with this lens, the exit metadata refers to a focal distance of 140mm, even when I know it was different (I tested that). Thus, since this is also an old lens, I guess it might have some problems and need a calibration as well. Further, I noticed that the 70-200 has some pincushion distortion, which is visible only when I open it in Adobe ACR and do not apply any lens profile correction. In the camera lcd screen it doesn´t show up because, as mentioned before, it is a JPEG camera corrected image.Finally, I also checked the sensor as suggested, and it seemed normal to me. Turning "Auto distortion control" on and off in the camera doesn´t make much difference, at least with the 70-200mm. I haven´t tried yet with the 17-35mm.Thus, it all points to be problems with the two lenses and not with the camera body. Anyway, I will try to do more tests with the 17-35 in the next few days to try to confirm this.Best Regards and thanks again.</blockquote>
