|Olympus E420 storage capacity
10 Megapixel is an average resolution and may be looked upon as a standard; the file size is growing considerably also due to the low compression factor Olympus use. The JPEG quality of Olympus is fine thanks to the small data loss (compression 1/2.7) and an excellent algorithm. If you choose the highest JPEG quality, you can count on a 6.8MB file. A storage capacity of 2 to 4GB seems the average storage capacity then, certainly when shooting during holidays. If you go for RAW, you should count on 11MB per picture!
|Shoot 8 RAW images sequentially
The Olympus E-420 is capable of shooting 8 RAW pictures sequentially in a little over 2 seconds, which comes down to 3.5 fps. Hereafter the speed drops to around 1 fps until a memory card is full. Writing the RAW pictures to a card (measured after the last RAW picture in a sequence of 8) it takes approximately six seconds. The test was carried out with a SanDisk 2GB Extreme III CompactFlash card.
Olympus E-420 offers USB 2.0 support
Like its predecessor, the E-410, the Olympus E-420 features a fast USB 2.0 interface; a USB 2.0 Hi-Speed. Taking into consideration the file size and the amount of pictures being transferred to a computer or notebook, a fast USB 2.0 Hi-Speed is almost a necessity. In any case for those who find speed a must in their digital work environment. In addition you can make use of a fast Extreme FireWire reader of USB 2.0 Hi-Speed card reader by SanDisk, providing this fast connection is available on your pc or notebook.
Olympus PS-BLS-1 Lithium Ion battery
The PS-BLS1 Lithium-Ion battery with a capacity of 7.2V 1150mAh is also used for the Olympus E-420. Olympus have shown to have the energy consumption nicely under control, and this new DSLR model also benefits from this. The Li-Ion battery is inserted in the bottom of the camera and is neatly covered by a small, oblong lid. The battery should be kept small since the camera is very compact too. The battery has a strong concept and lasts for about 500 pictures.
