I think the NEX6 shutter is probably rated for about 100k actuations. NEX 7 was reportedly 150k, and the new A6500 is specified as 200k. Btw EXIFTOOL also has no problem reading image count in Sony - eg a random image from my old NEX-F3.

Image/Shutter actuation information in Sony Alpha JPG and ARW files
Besides the 'normal' information (such as shutter speed, focal length, aperture, etcetera..), the EXIF from the original image file (straight out of the cam) usually contains additional information in the so-called 'maker notes'.
Sony Shutter Count FreeThe number of actuations is covert and stored as three bytes of data in the maker notes. This is the case for all Sony DSLR/DSLT and NEX cameras, except the following ones: A100, A200, A300, A350 and A700.
The initial findings of the corresponding SonyTags for A900/A850 were discovered and published first on German mi-fo.de forum by it's member 'Hans-J.' . Based on this info Dyxum member 'Guy' was able to further identify the corresponding SonyTags used, which hold the shutter actuation data, in all the other Alpha cameras in the maker notes and also set up a small tool site - http://tools.science.si/index.php - to calculate and report back the shutter count via a script by simply uploading an unedited JPG or (c)RAW to this server.
Calculation of shutter counter from these three SonyTags is done as follows:
And here's the list of SonyTags identified so far in the maker notes of the Alphas which hold the info:
These special SonyTags and their respective data can be extracted via exiftool - for details see here.
Sony Alpha Shutter CountMind that the file, to give you the shutter actuation data, has to be unedited as most image editing software will strip out the info required from the maker notes!
Furthermore these counters do not correspond 1:1 to the file image number given on the memory card, but rather are higher due to the fact that shutter was actuated during tethered shooting or intelligent preview (A900/A850); some shooting functions even make multiple actuations such as sweep panorma, multi shot iso mode, hand-held twilight even though only one image is recorded in the end.
