Casio EXILIM EX-V7 | Digital Camera Review | Storage and Energy
As is usual for most digital compact cameras, the Casio Exilim EX-V7 uses Secure Digital memory cards and supports the new SDHC standard. SDHC stands for Secure Digital High Capacity and is available with a minimal storage capacity of 4GB. The Casio Exilim EX-V7 is powered by a thin, long Lithium Ion battery, which can be charged with the charging station included. The charger also connects to a computer or television.

Casio V7 - SanDisk Ultra II SD memory card
The Casio Exilim V7 has a standard resolution of 7 Megapixels. For the most applications this resolution is more than enough. An added advantage is that do not have to invest in extra capacity, unless you plan on taking the Casio on a trip around the world. It is also not so important to have a very fast card, although the SanDisk Ultra II is recommended. Writing to the memory is fast and the photos can be written quickly to the hard drive. For storage capacity, I would say that 256MB is the absolute minimum, and 512MB is recommended. The table below shows how many photos fit onto a 256MB Secure Digital memory card.

Casio Exilim EX-V7 - USB 2.0 Hi-Speed interface
The Casio Exilim V7 is equipped with a USB 2.0 Hi-Speed interface, which transfers the images very quickly. During the practical tests I have used the Casio Exilim EX-V7 camera in combination with a very special type of Secure Digital memory card: the SanDisk Ultra II Plus SD memory card. This has the same format as an SD card, but it has a unique attribute: removing the card from the camera and splitting it open will transform it into a USB interface. This way you can plug the card directly into a USB port and have access to the photos or video recordings on the card, so that you no longer need USB cables or card readers, even the camera is redundant in transferring your photos to your computer.

Casio Exilim V7 - 950mAh Lithium-Ion NP-50 battery
Casio has chosen to supply this camera with a 950mAh Lithium-Ion NP-50 battery. This battery is exchangeable, but taking along a second battery is not very useful. You have to charge the battery while it is in the camera with the cradle which is included. This makes carrying it with you while travelling less pleasant. The advantage is that you can hook everything up to the charging station when you are at home, and quickly connect the Casio Exilim EX-V7 digital compact camera to the computer. For the manufacturer the advantage is that they can make a more compact design. According to Casio, with a fully charged battery you can take about 240 photos, which is reasonable.
