My 5d mark 3 says it can't recognize card1.

I have a fairly new  5D Mark 3 and it is saying it won't recognize Card1. It says to format the card but the camera will not do so. Very dissapointing in a new and expensive model camera. I have tried new cards and old cards and get the same message with both. Any help will be much appreciated.

If it's new, then contact your store or Canon for support.  That's why you have a new camera warranty.

 

CF cards aren't new technology.  I have heard of people forcing them down a bit too fast & hard and bending pins.  I generally push my cards in to the point where I can feel the card start to kiss the pins... then give it one more gentle push to seat the card completely.  

 

If you visually look inside the card slot, you should be able to see all the pins pointing straight at you.  Make sure you don't see any bent pins.

Thanks for the response. No bent pins that I can tell. Was hoping there was and easy solve and I wouldn't have to send it in.

Before you send it in, you can try several things.

 

First, since you say that this is happeing with multiple cards, it's probably not the memory cards at fault. Most likely it's a problem with the camera and the most likely thing with those is a bent or broken pin in the card socket. It can be hard to see a bent pin. Look again, very closely, with a flashlight and magnifier if possible.  Also sometimes a pin breaks off inside the memory card, so look very carefully at the business end of all your memory cards, too.

 

If you are certain the socket and cards are fine, next you could try "rebooting" the camera, which is much like rebooting a computer. This can clear bad instructions that are "stuck" in memory. To do a reboot, turn the camera off, remove all the batteries including the silver memory battery, turn the camera on and press the shutter release button once. The shutter won't fire, but this should deplete any and all electrical charge remaining in the circuitry, resetting  the camera to factory defaults and clearing everything from memory. Turn the camera off, reinstall the batteries, turn the camera back on and check the date/time. If it needs resetting, you got a proper reboot. If not, you might have to try the slower method, same as above but just turn the camera on and leave the batteries out for an hour or so while the remaining charge in the circuitry slowly drains. Once again, turn the camera off, reinstall the batteries, turn the camera on and check the date/time. There are no guarantees this will solve the problem, but sometimes it does and it's free and pretty easy to try.

 

If the reboot doesn't solve the problem, one more thing you might try is reinstalling (or updating) the firmware. Go to the Canon website, download the latest firmware and follow the instructions carefully. However in this case something I am concerned about is that a freshly formatted memory card has to be in the camera while doing the install. I haven't tried it myself, so am not sure if you can use the camera's second memory slot for this purpose. But, if you can, a firmware update/reinstall might solve the problem. It's possible that something got corrupted in the firmware. Again, no guarantees this will help, but it's free and fairly easy to try.  

 

If neither of those help, then I'm afraid the camera needs to be looked at. If you've have it only a short time, the retailer might help you. Otherwise, contact Canon about warranty repair or replacement under warranty.

Thank you. I will try re-booting the camera.

 

Appreciate your help!

Oh no!!  After looking and posting and looking some more (I've been at this literally all night!), I think you've hit it!  I'm old-ish, but with a magnifying glass and lots of cursing, I think I can see bent pins in MY card slot....now what?  I guess my camera has to go to the shop, right?  I don't suppose I can get in there myself??  And I guess I better put a PS on my earlier post, asap....thanks for the help!

You can straighten the pins yourself.  You need a pair of jeweler's long needle nose pliers.  The pins are quite soft and they can be broken off so you may still be better off sending it to Canon.

I doubt this is warranty but Canon may fix it for free if you have not had it very long.

Tweezers will also work in a pinch. 🙂

 

Disclaim: I have tried this on a card reader and not in the deep recesses of my camera. I'd probably have my camera professionally repaired if it had a bent pin. There's just not much room
