Canon PowerShot A710 IS | Digital Camera Review | Storage and Energy
Like most digital compact cameras nowadays, the Canon PowerShot A710 IS uses the popular Secure Digital flash memory cards. The Canon A710 IS camera is also suitable for the SDHC type cards, the new standard which allows you to use cards larger than 2GB. The first Secure Digital High Capacity (SDHC) cards are already available from 4GB and will eventually go right up to at least 32GB. The camera comes with a memory card, but this friendly gesture from Canon isn't much use as you can't do much with 16MB. It's a nice gesture, but as far as I'm concerned they can ditch the cards.

Canon A710IS - Secure Digital memory card
At 7 Megapixels, the resolution is nothing out of the ordinary, but you usually need more storage capacity than you thought. In the highest quality, a file from the Canon A710 IS digital camera uses a fair amount of bytes. It would be wise to use a memory card with a storage capacity of at least 512MB, or even 1GB if you like to take a lot of shots. Price is not a reason not to buy a higher capacity Secure Digital memory card immediately. The prices are very reasonable and the SD card has a lot of adjustment options. In the following table you can see how many pictures fit onto a 512MB card.

Considering a storage capacity of 512MB:

SanDisk Ultra II SD memory card
The Canon PowerShot A710 IS has a maximum continuous mode of 1.7 frames per second. It is not amazingly fast, but fast enough for a camera in this level. A fast card is useful, but not necessary for recording and reproducing the pictures quickly. With a memory card like the Ultra II or the Extreme III from SanDisk, you can keep taking photographs until the card is completely full, something you can't do with ordinary cards. This is where the card's processing speed becomes an issue and the camera will have to adjust itself to it. You will have to ask yourself if it is worth looking around for a fast card. Fast cards have the advantage that they can be transferred quicker to a computer. If you don't use a card reader, it is definitely worth your while to buy an Ultra II or Extreme III. The quicker the photos are transferred, the less energy it takes. I would advise you to use an external card reader like an USB 2.0 Hi-Speed card reader.

Canon PowerShot A710 IS - AA format batteries
For an energy source, the Canon PowerShot A710 IS uses two AA format batteries. Canon supplies two alkaline batteries with the camera. They last a reasonably long time, approximately 75 pictures. It would have been much better if Canon had supplied a set of NiMH batteries with a quick charger. That would have enabled you to keep shooting for longer as well as being more environmentally friendly. With NiMH batteries, you can take more than 300 pictures if you are using the LCD display. If the LCD display is turned off and you use the optical viewfinder instead, you can take twice as many photos. It's a good thing after all Canon still equips its entire compact camera's with an optical viewfinder!
