May 21, 2019 The Leica Q2 is an impressively capable fixed-lens, full-frame camera with a 47MP sensor and a sharp, stabilized 28mm F1.7 Summilux lens. It's styled like a traditional Leica M rangefinder and brings a host of updates to the hugely popular original Leica Q (Typ 116) that was launched in 2015. If there's one thing that you can say about Sony's digital camera business, it's that they've experimented with many different concepts. From SLRs with dual autofocus systems and 'Translucent' Mirror Technology to its NEX mirrorless line-up, Sony has gone down virtually every avenue in digital.
This thread is a short condensed summary of all the findings and informations discovered so far w.r.t. Image/shutter counter tags in the maker notes of Sony Alpha cameras.Intentionally posted as a read only reference which will be updated in case there are any new findings. Questions or further discussion, please use the referenced threads stated below!Image/Shutter actuation information in Sony Alpha JPG and ARW filesBesides 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'. The 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 by it's member 'Hans-J.'
Based on this info Dyxum member 'Guy' was able to further identify the corresponding, which hold the shutter actuation data, in all the other Alpha cameras in the maker notes and also set up a small tool site -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:all bytes are MSB on the left: Tag3 Tag2 Tag1SUM = (Tag3 ). A900/A850 with 65k shutter actuations - anyone?

A100 / A200 / A300 / A350 / A700:no such 'counter' tags in maker notes directly; most likely data is encrypted and accessible via service tools only, like KM5Dhi,I have read it in the begining.well here is 'maker notes ' tags.actually there are hundred of tags.the only problem we dont know their relationship in order to calculateSony Focus Info 0x0846 126Sony Focus Info 0x0847 3Sony Focus Info 0x0848 231SteveSavage. Just a note after playing a bit with ExifTool: in case of the group of cameras in which NEX-6 resides it is only possible to retrieve info about 'Image Count' but IMO this term is misleading and should be replaced by 'Exposure Count'.

The problem is that those cameras allow one to use multi-exposure techniques like 'free-hand night shot' (or whatever Sony calls it) and 'sweep panorama'. For example the former forces the camera to fire 6 exposures and combines those shots into one. As a result you get files which are numbered in a consecutive way e.g. DSC0129 and DSC0130 whereas the ExifTool reports e.g. 1499 and 1505 respectively.
