The presence of a dual card slot you means that as a user, you fortunately no longer have to depend on the xD Picture memory card. The xD market share is limited and it appears that its development was given up a few years ago. At the time the xD Picture card was introduced, there was still talk of 8GB storage capacity, but that did not happen in reality. A maximum of 2GB storage capacity is its reality while SDHC in fact provides already 32GB storage. And from that platform, a new SD-type is ready to roll. SDXC will offer a maximum storage capacity of 2TB, which will make every competitor pale in comparison. With support for CompactFlash, in addition to xD, at least 32GB is available.
Olympus E-450 - JPEG & RAW photos
With a 10 Megapixel resolution and JPEG storage, in addition to RAW, for digital pictures, the file size is not too bad. For the highest quality JPEG, the size is around 7MB, for RAW format it is 11MB. The buffer can handle up to 8 pictures (RAW) in one go and the Olympus E-450 is capable to shoot action shots at a frame rate of 3.5 fps. 4GB of storage capacity will be sufficient for most situations at this time. A second card as backup should not be a problem, thanks to the fact that prices have dropped lately.
Olympus E-450 - USB interface & Card reader
Below the display, a rubber cover hides access the USB interface. The Olympus E-450 is equipped with a fast USB 2.0 Hi-Speed interface for swift and easy transfer of pictures to a computer or notebook. However, there is a downside to this transfer method. And that is the need for a separate cable. In our work environment, we only make use of a card reader. These readers are external and also available as built-in versions, while often providing support for multiple types of memory cards. Another advantage is that you no longer need to work with separate cables, and only the card is needed for data transfer. The camera itself can then be used to keep on shooting, with a different memory card inserted.
Olympus PS-BLS1 Li-Ion battery
The Olympus E450 gets its power from a PS-BLS1 Li-Ion battery. The battery has a capacity of 7.2V 1150mAh and should be recharged by the included battery charger. Charging the Li-Ion battery takes about 3 hours and 30 minutes. The amount of pictures that can be made with a fully charged battery depends on the conditions in which the shooting takes place, as well as on the manner of photographing. To be able to carry out a standardized measurement, CIPA (Camera & Imaging Products Association) has developed a clearly defined method by which an average number of pictures on one battery load can be calculated. For the Olympus E-450, some 500 images can be made with a fully charged Li-Ion battery.
