Shooting with a Sony A7iii, that I bought last year as a new camera, it sometimes happens that I see this phenomenon.


No, I didn't switch off the camera to soon, as this one is just somewhere in a burst shot. All other shots around this one don't have this.

It also happens, sometime, when I make a single shot.

Please, who can comfort me with the reason?

Oops, that doesn't look good but it can happen in many places. Can be the camera but also the memory card or a glitch in tranfering the image to the computer.

Here's some questions (and maybe tests) you can do to determine if it's the camera or something further downstream:

When it happens do you also see it on the LCD when reviewing the shot?

Are you shooting raw or jpg? If you shoot raw+jpg do both images show this when it happens?

Does the problem happen with different memory cards or only with one (which might be faulty)?

Yes.

I'm shooting RAW nowadays, but when it occurred for the first time, I saw it also on the JPG-file, that was stored on the other memory card .

Not tried yet. I'll swap some cards from one camera to another.

To be continued and thanxs so far.

I have another question - does it always appear at the same place in the frame or every time it is in a different location?
To me it seems as a problem with file writing/reading, but can also be a sensor problem.

Broken electronics on the sensor, memory or a defective memory card.

Replace the memory card first - and retry.

Yes, I'm doing tests with another memorycard in this camera and the suspected defective card in my other camera.

As soon as the lines re-occur, I'll be back...

Switched the memory card to my other camera and placed the other memory card in this camera.
As Mr. Murphy would confirm: nothing happened. All shots were without the nasty line.

I go on

Another week gone by. Nothing again.

Just a few shots with bad luck?

I'll swap the memory cards to their original camera and see what will happen. Fingers crossed.

Is 1 or 2 missed pictures out of 5000 reason enough to buy a new memory card and to bin a card that is not very old and costed about 65?

I don't like binning good stuff.

Yes, put the memory card back and yes, it happened again.



But:
on the left: the RAW-file
in the middle: JPG straight out of the camera
on the right: developed in LR.

So, I can't blame the memory card, but have to blame LR or the writing (on a SSD) from LR to the disc.

Puzzling.

What sort of reader or cable you use to transfer image files into your computer?
Does those lines ever show when you review the photos on the camera?

What if you use a different RAW converter?
I assume the RAW picture on the left is by a viewer, correct? That will be an embedded JPEG, not a RAW picture.

If it is showing lines, it is not "good stuff" and you could also use it as a back-up memory card.

The A7 III has two memory cards, did you use redundant shooting? It is there for this kind of situations.

I am guessing it is a memory error on the editing PC. Either the main memory or the video card memory. A lot of consumer video cards are not very stable. There may be a way to disable the GPU assistance in Lightroom. If that fixes it then it is definitely the video card.
