Memory Card Puzzlement: I have two cameras, a Nikon D3100 and a Nikon D7100. I had a SanDisc SDHC 8GB Card with the Number 4, circled, in the D3100. I had a Lexar, PLATINUM II, 16 GB...

I have two cameras, a Nikon D3100 and a Nikon D7100.

I had a SanDisc SDHC 8GB Card with the Number 4, circled, in the D3100.

I had a Lexar, PLATINUM II, 16 GB Card with 200x and the Number 10, circled , in the D7100

The D3100 had a 55-300mm Nikon lens attached to it and the D7100 had a 150-600mm Sigma Contemporary lens attached to it. The D7100 system weigherd about 8 pounds and I wanted to view the images I had just taken with it so I thought I would switch memory cards and view the Lexar Card in the much lighter D3100 setup. When I did, a got a message saying " Folder contains no images." When I loaded the SanDisc Card in the D7100, I got the same message. When I returned the cards to the cameras they were in originally, they both worked fine.

Does anyone know what this is all about? It's a complete mystery to me!!!

They are different models of cameras and if you format the card in your camera, it's like customizing that card for that camera, a different camera will have trouble reading it, because the card has not been "customized" for it!

Thank you so much!! That makes a lot of sense.

By default the camera is configured to show only messages in the folder selected for new images. Of course that folder is very specific to the camera model. Hence is says that the Folder contains no images. But it is only looking at that folder, and not at what else is on the card. The card itself is not specific to just one camera!

Go to the "Playback -> Playback folder" menu and select "All". Then press the >> button to display images, including those from another camera.

I have three different camera brands: Nikon, Canon, Sony. The same thing happens when I switch SD cards of any ilk. When I remove the card and open it in my computer - with it's SD card mount, not only are the prior camera's files there but the new files also. Whereas I don't recommend it, I have not lost a photo in any change of camera. The camera just opens a new folder for the current camera.

Try it with non critical imaging. BTW, I have only done this in an emergency - Typically I retain all by cards and use them one time. They become part of a double redundant system the works for me. Cards are inexpensive!

Many thanks. I changed the Playback Folder to All as you suggested on both cameras and both cards can now be viewed on both cameras. I'll probably leave it that way. I'm sure there are disadvantages for doing that but I can't see any. Just out of curiousty, are there any?

I haven't found any disadvantages, as such. I haven't thought much about it though...

No problem. I'll just leave it on ALL and forget about it. Thanks again.

I use maximum 8 Gb memory cards and I have committed the cards to specific camera's.

No way I want to lose 32 Gb of images because one card goes teats up on me.

We had a wedding photographer, who when he switched from film to digital, he was excited to be able to shoot without reloading camera's with film.

Imagine his surprise when he shot his first wedding on one 32 Gb and put the card in his computer, and it was BAD and non recoverable.

Now, imagine his relief when he discovered that he was very smart to have his assistant backing up the wedding on his film gear (just before I purchased his medium format film gear).

Not totally committed yet, he save His OWN Ass... rather his assistant did. He now rotates 8 Gb cards, as does his assistant.

I agree with him. Who needs 32,000,000,000 bytes of information on one memory card.

Or is it 32,000,000,000,000????

Many thanks for your interesting reply.

I'm curious as to the significance of the circled numbers on the cards. I've never really looked at mine to see if there are numbers circled on them or were they put there by you?

This should answer your questions.

I have no idea what the circled numbers mean. Why not post the question by creating a new topic? I'd like to know as well.
