|Panasonic Lumix TZ1 - Storage capacity
The Panasonic TZ1 comes with an internal memory of approximately 134MB. It's a nice gesture, but you can't really do anything with it. Internal memory is a good option in itself, but then it should be increased to 64MB, for example, so that it can come in handy as a reserve. The file size of a 5 Megapixel digital camera like the Panasonic DMC TZ1 is a bit larger than 2.5MB (JPEG - 2560 x 1920 pixels / aspect ratio 4:3). The internal memory is good for just a handful of pictures. If we take 3 film rolls of 36, 108 pictures in total, you will need approximately 280MB. A memory card of 256MB or 512MB would combine well with the Panasonic Lumix DMC-TZ1 digital camera. The Panasonic TZ1 supports memory cards with a storage capacity of up to 2GB, so the new 4GB SDHC Secure Digital can't be used in combination with this model.
Panasonic TZ1 - Secure Digital memory card
The compartment in which the Secure Digital memory card is inserted is underneath the Panasonic Lumix TZ1. I used a different SD card for the practical test: the SanDisk Ultra II Plus Secure Digital memory card. As well as being a means to save pictures, this type of card also includes a handy USB interface. It works very simply: remove the card with the saved photos from the camera and bend it in half to reveal the USB interface. Place the card in a free USB port of a laptop or desktop computer and you can read or write data onto it immediately. The speed of the Ultra II memory card is more than enough to enable the Panasonic TZ1 to work continuously or to record high resolution video clips (VGA - 640x480 pixels/30fps).

|Panasonic Lumix DMC-TZ1 - Burst function
The integration of the Venus Engine III processor has made the Panasonic Lumix TZ1 extra powerful. This means that the Panasonic is capable of shooting a quick series of pictures in succession. The Burst function is good for approximately 3 pictures per second with a maximum of 3 pictures. You can take pictures continuously at a speed of 2 frames per second until the flash memory card is full. It is advisable to buy a quicker memory card than the standard SD card to prevent your card from becoming the weakest link.
Panasonic DMC TZ1 - USB 2.0 Full Speed interface
The Panasonic Lumix TZ1 has a USB 2.0 interface, type Full Speed. Despite its name, this is not the quickest variety, i.e. the Hi-Speed interface. The difference in theoretical speed is 12Mbps or 480Mbps, which is a considerable difference. In practise, it doesn't reach this speed but then a 5 Megapixel digital camera doesn't really need a Full Speed variety. Transferring from a full card takes several minutes, but this is acceptable. If you need more speed, you could buy an optional USB 2.0 Hi-Speed card reader; you will need a USB 2.0 Hi-Speed interface connection on your computer to really benefit from the speed.
Panasonic Lumix DMC TZ1 - Lithium Ion battery
The compartment in the Panasonic TZ1 in which the memory card is placed also has room for a rechargeable Lithium Ion battery. The camera runs on a Panasonic CGA-S007E 7.3V 1000mAh. Measured according to the CIPA standard, this capacity is enough for approximately 250 pictures or approximately 125 minutes. The play time of pictures saved via the LCD screen is approximately 260 minutes. Recharging a battery via the charger takes about 170 minutes. These are good figures and probably more than enough for more than enough to get most consumers through the day. Of course, it is possible you are unable to recharge the battery during a day trip, party or on holiday. In that case, you should buy a second battery.
