Question about camera memory card?

I just bought a new digital camera that is 7.1 mega pixel and I was wondering if I take the memory card out of my old camera which is 4 mega pixel and put it into the new one, will it cause a problem. Don't want to damage anything since This new camera wasn't cheap

or should I just buy a new one since my card is just 512mbs

As long as both cameras take the same type of card (SD, CF, XD, Memorystick, etc.) you can. But expect about 1/2 the number of pictures with the new camera. My suggestion? Memory cards are so cheap it's easier just to buy a couple. I picked up a couple of 1 gb cards for under $10 and a 2gb for $19 recently. Look for weekly sales in the paper.

You can keep your old card as a backup, or, if you wisely invest in a memory card reader, use it to transfer photos from your computer to a friends. Use the old card as a photo album to share with friends (but ask for it back!).

Hope that helps.

It should be fine, you just won't be able to save as many picture's using the new camera, because the pictures will probably take more space

it depends on how often you use it, and other settings your camera has, I am guessing it will probably be at least 100 pictures with that card, but when you put it in the camera, a lot of them will tell you how many you have left
So if you won't be able to move them from the card to your PC, before hitting the actual limit, then you may need another card.

It will work fine just as long as the card is the same (e.g SD card, CF, MMC, Memory Stick) as the other. Dont forget to format the memory card in the new camera. You can look for the format function in your manual or settings in the camera.
