Looks like something wrote some bad EXIF.  There should be no SubIFD in the EXIF of a JPEG image.

I tested this with Irfanview 4.36.  I loaded a .Nef from my Nikon D5100 and here is the output (-g1 -exiftool:all  -exif:all):

When I do the same to an old .Nef from a D5000, all I get is

You lost me.  Is this the D5100 output from an NEF file or a JPG file?  If NEF, then why does the IrfanView version matter?  I thought we were talking about JPG images.  Does IrfanView modify NEF's?  If so, it looks like it is corrupting these.

The D5000 output makes no sense either.  I have lots of original NEF (and JPG) samples from the D5000 and D5100 and ExifTool extracts a ton of information from all of these, with no warnings.  I don't see how you can get no output and no warnings.

I added info

[Phil Harvey]

OK.  I'm just going to go ahead and suggest rebuilding the EXIF of the JPG images to fix the problems.  This is explained in FAQ number 20.

already it works

thanks

Sorry for lack of clarity.

I took a nef created by a nikon d5000 and d5100.  I loaded each nef into irfanview, and then saved them out into Jpg format, which is what my understanding of what the OP was doing, except with a d7000 and also using ViewNX2.  I don't using ViewNX2, but I use Irfanview a lot, so I was trying see what my results would be with pictures from my cameras.   I included the Irfanview version number just in case anyone else tried it and come up with something different.

I ran ExifTool -g1 -exiftool:all  -exif:all on each of the converted Jpgs and the results were pasted above.  I don't believe that Irfanview can modify nefs, just show them.

[Phil Harvey]

IrfanView is definitely doing bad things with the EXIF it writes to the JPG.  There should be no SubIFD.  This bug should be reported to IrfanView.  Also, the lack of EXIF in the D5000 image is odd.  From ExifTool's point of view, there is no difference copying the EXIF from D5000 or D5100 NEF to JPG images, so I don't know why there should be a difference with IrfanView.  I would report this as well, as a separate bug.
