Has happened a few times now and starting to worry. I format my card in camera and download using a card reader.

 
Happened on my 1DMK2 which i know is older tech but I am certain it happened with removing from the cheapo card reader I was using.

However I binned my CF card as it was 7 years old and to further muddy the waters and general confusion I had to send the 1DMK2 away for repair. Turns out that the CMOS in need of calibration, shutter springs wore to buggery and camera was internally filthy.

This probably won't help you but I'd look at the CF and the sequence that produces similar images. I'm brain dead and its been nearly two months since i seen this.
 
Thanks for the replies, it's not a cheap card though but could be near the end of it's life I suppose, I've had it for over 2 years now. Will buy some new ones
 
That's what my 40D did when the shutter was on its way out :eek:.
 
How are you transfering the images? Plugging the card into a reader or plugging the USB into the side of the camera? Which ever one your doing try the other.

How long after the transfer are you unplugging the memory card/cable?

This to me looks like its corrupting the image because its being unplugged before its completed the transfer.
The reason i say this, i get this problem with a crap memory stick every time if i just pull it out. I have to eject it fully via the icon on the system tray (windows) to make sure.

Oh no, Jo, I hope it's not that :( It's happening to about 1 in every 900 and about halfway through

I'm plugging it into a card reader, haven't tried connecting the camera, will do that this weekend then, have only had 3 so far and about 1 in every 900

I leave it plugged in until they're transferred and I've checked they are all in the folder before I unplug and it's about halfway through the set. I disconnect the card reader via the icon as well
 
Are you sure it's happening on transfer?

I had a few problems like this when importing RAW images into Lightroom. Re-importing usually sorted it out.
 
I had this a few years ago with my first camera, a Samsung compact.


Turned out to be the memory card, not a single photo from the trip was correct :(
 
I see this a lot at work, I live in a town with a large elderly population with cheap point & shoot cameras and equally cheap memory cards. 99% of the time, the problem lies with the cheap memory card. They never learn, I've seen one customer twice with this problem now. I advised buying a proper branded memory card like sandisk, kingston, lexar, whatever. But no, they came back with an even more flimsy card than before :bang:

I'm not suggesting you have a cheap card, just speaking of my experiences with exactly the same problems!

I hope it's not your shutter either, that would just suck big time.

Yup, it really would :gag:

I'll reimport then and see if it's that, I haven't yet wiped them off the card

I'd rather it be the card than the shutter though

If it was a cheap one, I'd understand but it's a Sandisk Extreme III so not exactly cheap, just might be on it's way out


Thanks all for your replies
 
I had this with some old shots on my Finepix F450 years and years ago. It only happened after my hard drive had gone kaput though; I ran a recovery programme and got all my old photos back, but some of them were corrupted in the same way as your pic.

Or, of course, it could be your camera's in-built 'leg censor sensor' ;)
 
Yes it was, Neil, they's just missed a goal so I was firing off a burst to get the disappointment

Did you see full image on the camera before downloading it?
when you down load are you keeping the images on the card till you checked them? if so check the card image on camera....

Do you know, I don't know actually, I still have the pics on the card as I won't reformat til I've backed them up on my external hard drive so I'll havae a look

but it's only the 1 pic out of around 900 on this particular set, that's what confuses me

and groan - that was just awful :lol::lol: you haven't changed, have you!!!

I've had exactly the same thing happen to me when taking multiple frames before. When taking bursts of frames it takes a short period of time to transfer the data between the onboard cache and the card. If you power down the camera before the data is written you only get half a photo. I assume theres the possibility you might even lose a frame or two. The data transfer rate is obviously better with the faster cards for which you pay a premium. If the picture displays like that on your camera as well as on the PC it may well be your problem. Its usually the last picture in the burst you took which could account for the 1 in 300 shots.
 
Thanks for your reply. It's only the 1 out of just over 900 I took that day and I did quite a few bursts. I didn't power down though as I carried on taking the match photos.
 
Was it half-time :)

Sorry.

That looks like data corruption to me, probably caused by your card going a bit dicky - is it only on one card? I had this happen once on a Lexar card nut I understand the 'fake' sandisks do the same thing

I seriously doubt it is shutter - you get a very similar effect when a shutter is failing but that is partial exposure of the frame and yours is definitly not that.

Agreed - it would be like having a very short black to transparent gradient over the image I imagine, not a single pixel interface between the grey area and the image
 
the card may be failing then.. what i suspect has happened is that for some reason the card could not keep up with the burst of data and one of the images corrupted.

replace the card and try some burst test shots.
