Cameras that use this method:
A230 A290 A330 A380 A390 A850 A900

There is only one counter discovered in this method. It appears to count the number of shutter actuations/images taken.

Shutter count fields:
Sony_FocusInfo_0x0846 = A
Sony_FocusInfo_0x0847 = B
Sony_FocusInfo_0x0848 = C
SUM = A + (B * 256) + (C * 65536)
SUM = (C<< 16) + (B << 8) + A

Cameras that use this method:
A450 A500 A550

There is only one counter discovered in this method. It appears to count the number of shutter actuations/images taken.

Shutter count fields:
Sony_MoreInfo0201_0x014a = A
Sony_MoreInfo0201_0x014b = B
Sony_MoreInfo0201_0x014c = C
SUM = A + (B * 256) + (C * 65536)
SUM = (C<< 16) + (B << 8) + A

Cameras that use this method:
A33 A35 A55 A560 A580 NEX-3 NEX-C3 NEX-5

This is the only method that has two counters.

The first is for images taken:
Sony_MoreInfo0201_0x011b = A
Sony_MoreInfo0201_0x011c = B
Sony_MoreInfo0201_0x011d = C
SUM = A + (B * 256) + (C * 65536)
SUM = (C<< 16) + (B << 8) + A

The second is for total shutter actuations:
Sony_MoreInfo0201_0x0125 = A
Sony_MoreInfo0201_0x0126 = B
Sony_MoreInfo0201_0x0127 = C
SUM = A + (B * 256) + (C * 65536)
SUM = (C<< 16) + (B << 8) + A

The difference is that the camera makes two shutter actuations when shooting in live view mode and takes one image.
In case of a multi exposure mode (Multi shot ISO, hand held twilight, panorama, HDR) the camera takes multiple images and makes exactly one more shutter actuation as the amount of images taken.
Note that panoramas can consist out of 50 or more images.

Cameras that use this method:
A37 A57 A58 A65 A77 A77M2 A99 NEX-3N NEX-F3 NEX-5N NEX-5R NEX-6 NEX-7

This is the latest method used by SONY.
There is only one counter discovered in this method. It counts shutter actuations. With the electronic first curtain shutter the camera makes one shutter actuation per exposure and without it two shutter actuations are required per exposure.

Shutter count fields:
Sony_Tag9050_0x0032 = A
Sony_Tag9050_0x0033 = B
Sony_Tag9050_0x0034 = C
SUM = A + (B * 256) + (C * 65536)
SUM = (C<< 16) + (B << 8) + A
