Sony Shutter Counter


Recommended Posts

Handy for checking out a new body.

I don't know about the NEX, but on the A55 with the pellicle because of the shut-open-shut-open cycle you get a shutter actuation count as well which is almost, but not quite, double the exposure count. Interesting.

Either way mainly garbage, maybe a couple of hundred worthy efforts!   :rolleyes:  

 

I tend not to trust the preliminary histogram and typically take a few shots before I get the exposure that I want. Probably more of a problem using manual focus lenses.

 

It also includes video, no idea how that stacks up.

I tried it on an image from my NEX-6 and got just shy of 10K. However, I've been using this camera for only about 20 months, and I tend not to take a lot of duplicate or similar images (and no video to speak of), mainly because I hate having to weed through them all later on. At heart, I guess I'm still a film photographer. Haven't tried this program yet on my NEX-3, which I've had for over three years and still use quite often.

Well do you get two results, one for exposure count and one for shutter actuations? I'm curious.

 

This is what you get:

 

Detected Model: NEX-6

Shutter actuations made up to file _DSC1244.ARW: 1272

| | | | Sony_Tag9050_0x0032 = 248

| | | | Sony_Tag9050_0x0033 = 4

| | | | Sony_Tag9050_0x0034 = 0

(65536 * 0) + (256 * 4) + 248 = 1272

 

Allowing for a few test firings before the camera went on sale, 1272 exposures after 1244 shots looks about right to me.

I get

Detected Model: SLT-A55V
Exposures made up to file DSC00297.ARW: 20814
| | | | | Sony_MoreInfo0201_0x011b = 78
| | | | | Sony_MoreInfo0201_0x011c = 81
| | | | | Sony_MoreInfo0201_0x011d = 0
(65536 * 0) + (256 * 81) + 78 = 20814

Total shutter actuations up to file DSC00297.ARW: 35944
| | | | | Sony_MoreInfo0201_0x0125 = 104
| | | | | Sony_MoreInfo0201_0x0126 = 140
| | | | | Sony_MoreInfo0201_0x0127 = 0
(65536 * 0) + (256 * 140) + 104 = 35944

Presumably the NEX has the same close-expose-open cycle as the A55 but only has the one parameter and counts it as 1 operation not 2 and.

The A55 shutter is usually open, to allow permanent live view.

So when you press the release it has to close, open and close for the exposure, then open again. The A55 records that as one exposure but two (well, actually slightly less that two, on average) actuations.

I think my question is answered as I now read that the NEX has an electronic front curtain shutter. So this is presumably why it doesn't have to do that.
