The essential tool if you want to take pictures. Without these cards, you can not take it. Except in the case where the camera has an internal memory, but I have not yet heard.
There are several types of memory cards with storage capacities and transfer speeds different.
Operation is simple, open the cover of the card slot of the camera, put the card into the slot, close the lid and turn on the camera. On first use, it will make a card format. Even if you think it is formatted. Formatting card properly prepare for the device, with the creation of dedicated folders, formatting memory format ...
For perfect use, I advise you to have multiple memory cards. Problems for two.
1 - Lack of space is a problem inherant every photographers, whether professional or amateur. You are full of photos taken in a remote corner, unfortunately your memory card is full. They will remain open pictures to take. Lack of warehouse or delete photos on your card or you repack and go.
2 - The deterioration or loss of a memory card. Imagine yourself back from vacation, so you no longer have your card or it is unreadable. Farewell memory. For my part, I advise have three or four medium-sized memory cards. A 8GB size is a good compromise, especially with the current capacity of boxes.
Then comes the transfer speed of the card. You must first verify the characteristics of data transfer from your camera. Always take a card with a data transfer speed than that of your camera. It would be annoying to have to wait until the device transfer the latest photos, while an event to be photographed. I can confirm the problem, I have been confronted more than once. Following the purchase of new cards faster, my problem was solved.
Take usually called professional cards more expensive (30-50% more), faster, but at least you have a warranty up to 30 years for some. Moreover, the temperature range of this device is increased (-20° to +50°, instead of -5° to + 40°). imagine yourself on a trip Honeymoon in Lapland or in the desert, and can not take pictures. I personally had the problem in the high mountain and -15 ° with the wind temperature is even lower.

| A favor | Away |

 Having multiple cards. Transfer rate higher than that of the device. Memory medium sizes. Professional card tell. |
Having multiple cards. Speeds lower than the transfer of the case. Too big memories. |
