More memory means more high resolution, high quality pictures. The number of images capable of being stored on a memory card is based on the memory size of the card, the resolution of your camera, the quality selection you choose for the images and how the camera compresses the images.
Lexar Media Secure Digital (SD) Cards are designed for use in many digital devices including digital cameras, MP3 players, PDAs, cellular phones and camcorders. The Lexar Media SD Cards have an erasure-prevention switch to keep your data safe. When the switch is in the locked position, it will stop you from accidentally copying over or deleting data stored on your card. Now you know your data will be safe.
