What to look for when buying a used Fujifilm X-T2

gphoto2 is showing a decimal value for a 32 bit field where only the high level 16 bits are being used - you have to move the value 16 bits to the right to get the correct decimal.

for example 572522496 is 0x22200000 - remove 0000 from the right and convert back to decimal - 8736

572522496 - 8736

572588032 - 8737

and so on

It appears to increment for mechanical shutter only - at first I thought we had found the actual mechanical shutter count which a lot of people are looking for - but unfortunately (at least on my X-T3) it works OK for single frame and continuous low - but if you shoot on continuous high it seems to be overcounting by around 50%.

The Image Count from the EXIF includes electronic shutter but does seem reliable (except for rolling over)

Thanks much! This is really helpful.

There must be an internal counter keeping track of that difference between EXIF ImageCount and PTP 0xd154. I went back and tested with Electronic Shutter only, couldn't find anything changed in the PTP, but PTP d154 doesn't change neither.

That confirmed what you said, PTP 0xd154 is the mechanical count, while the EXIF ImageCount includes both mechanical and electronic.

Perhaps d154 has been initiated since assembling the camera, and ImageCount has been reset right before it's boxed (or an agent can reset it anytime). The difference between them, around 800+ mechanical count, perhaps were during QA testing.

It does seem strange that there appear to be two different counters - one visible through the tether process and the other written to the EXIF - the mystery continues
