I've had a few frames like this lately. The second looks like a composite of two frames. What's the smart money on? Shutter? Corrupt card?

Looks as if the shutter is not opening fully would be my first guess, the second picture also could be down to the childs movement with a slow shutter speed. I had similar with my camcorder with the curtain type shutter on the lens front which was sticking,

Does look like data curuption, had a similar issue with images transferred from a smart phone once, on another PC they were fine, in the end seemed to be a driver/USB issue. Just my thoughts though.

Don't think it's anything to do with subject movement and the files are like that when viewed in camera.

Mike, I'm inclined ot agree with you, I think it's the card which is a newish sandisk. Not the first one I've had problems with either.

Where was it bought from, dod?
Sandisk actually have a very good guarantee.

good point, my memory or amazon, I'll need to check, thanks :)
 
Lot of fake cards about too, agree with others and yourself, must be the card. (fingers crossed)
 
I would plump for corrupt card or corrupt data transfer?

Do you only have jpegs or do you have RAWs too?
 
Seeing first image I would have said shutter but was 2nd image taken in that orientation ? If so then must be card as its in the veritcle plane rather than horizontal
 
I'm going to be different and say the shutter.

The first image looks like could be either, file corruption looks exactly like that.

The second image is a strange one. If it was the card, where does it get the child's hair? It looks like it's the shutter that delayed close the bottom half.

The position at which the image goes bad also says it's the shutter. File corruption is not this consistent.

The second file is like a composite of two different shots. That would be consistent with the next shot in the series which had zoomed in closer on the child.

That would seem to indicate the card is not writing properly. That could be the card itself, or the writing bit inside the camera. One will be cheap and easy to fix; the other could be PIA.

Try a different card or the same card in a different camera.
 
Can't you try with another card?

I'd first say it's the shutter's bottom half curtain that has some kind of problem but, better thinking, maybe the card being corrupt could "write" parts of the images in the wrong places.
Did you format the card on camera?

Each image in a Digital camera is a single file, so accidental double exposures are impossible.
It could be the camera processor at fault or the Memory card, both can cause corruption.
best to try a different card to eliminate the first possibility.
 
It's not the shutter for me. There's significant blue coloration and also some funky artifacts etc at the transition between the two "halves" and I don't know of any way a delayed and stuck shutter/curtain could produce that. It must be some part of the image processing and saving pipeline, so for your sake I hope it's just a card problem. It's best practice to make sure you format the card in camera before using each time you've transferred the images to your computer. That might sort it, but personally I would never take the risk of a dodgy card. Just get another one.

Exactly, hopefully card, might be camera. It's just possible that it's dirty contacts.
 
It could also be your memory card reader, I thought I had a duff memory card because it produced pictures like yours until I changed the reader and they were all fine again, try all possibilities!
 
I had the same problem with a Sandisk card in a Nikon D80. I contacted Sandisk UK and they asked me to send it back and replaced it by return of post. I think they offer a 10 year guarantee on the current cards.
 
I would also vote for the card, shutter problems wouldnt leave a double exposure like image.
 
Definately not the shutter. Those lines are at a pixel level, the shutter would be slightly blurred at the boundary.

Plus on the second shot, the child would not be split along the plane.
 
If you've had this problem with more than one card (especially if they were both genuine Sandisc cards) that would certainly suggest a camera fault, be it shutter, or the card read / write assembly.
