Canon 1D MKIV and SD card problem
1

Hi all,

during the last couple of photo shoots my 1D MKIV did not recognize the SD card in the slot. Like there was no SD card in the camera. I tried another card same problem. Switched camera off , removed battery and all ok. It happened again and the same procedure solved the problem. I used the blower to clean the card slot too.

Is this a sign of a potential problem with the camera? Anyone experienced this problem with the 1D MKIV?

Thank you

Dang I hate getting old. It was either my refurbed 5D4 or my 7D2 that went back under warranty to replace a bad SC card slot. Worked for a while but then had issues.

As I think about this it was probably the 7D2 but they are very similar cameras except the sensor. Many shared features and perhaps components

sounds like a contact pin inside the slot that has gone bad, not making connection outside or inside the drive slot, but not bad enough to go out completely. this something for the technicians at the shop to check and fix, even if you find out the issue through troubleshooting process.

good luck.

What size SD card are you using (memory)?

Have you tried using the CF card slot, using a Digigear Wifi CF to SD adapter?

Those are fantastic- highly recommended! Not only are they great, but you can use SD cards with more memory than the 1D Mark IV is rating for- I currently use an 80ms Sandisk Ultra 128GB card! Zero issues. You do need to give the camera about 5 seconds to read the card after you close the card slot door before you turn it on. And of course you'll need to format it immediately because you'll get a pop up about it.

Mine works fantastic, been using it for months on end.

This is SD  card he is talking about not CF card with numerous tiny pins. The SD card with flat wide strip contacts does not have pins. I would simply try cleaning the contacts on the card and in the slot with squashed cotton bud dipped in IPA. If you have not used SD card for a long time the contacts might simply be dirty. If this does not help you might need your camera to be looked at by service.

Hi folks, yes it was the SD card not the CF. I cleaned the contacts at the time of the issue and it works without any problems, so far
