Konica-Minolta DiMAGE A2 | Digital Camera Review | Storage and Energy
Noticeable is the fact that the DiMAGE A2 gets warm when it is turned on for a short while. The back of the camera around the multi-functional button gets perceptibly warmer. We will look upon this as a positive contribution when photographing under wintry circumstances! Anyhow it doesn't effect the image quality in any case. The DiMAGE A2 is equipped with a memory slot for CompactFlash type I and II memory cards, and also the Microdrive. Personally I am not a fan of the Microdrive because of lack of trust worthiness of this storage medium. This medium used to be very popular due to the fact that the price of the Microdrive was considerably lower compared with the high capacity storage flash memory cards. However, prices have dropped tremendously in the last 2 years which decreased the market share of the Microdrive enormously. The risk of damage when falling down or bumping is high. In spite of the improvement on the new Microdrive (4GB) this risk is still very much present, in contrast to Flash memory cards, that can be handled rather careless.

The memory compartment is placed on the right side of the camera and is covered with a (plastic) cover that can be opened easily. After opening the slot is visible and the card can be inserted. Press a small catch and the card jumps out again and the slot is freed again. The DiMAGE A2 supports the FAT32 system, so a memory card with more than 2GB storage capacity can also be used. The camera has six different settings as far as resolution is concerned: from 3264x2448 to 640x480 pixels. Beside that there is a choice of three different JPEG compressions. And beside that an image can be stored in TIFF or RAW format and the handy combination of RAW + JPEG can also be chosen. This latter option is very useful to have an 'original' file with the raw unedited material and at the same time a JPEG format to work with.

The camera is rather fast when processing high resolution JPEG files. Processing the combined RAW + JPEG files is not the strongest side of the camera. This handy function will be bothered about its processing time. In practice unfortunately a processing time from over 16 seconds is the rule rather than the exception. Two different memory cards have been used for storage, an older unbranded CompactFlash memory card and the Ultra II 1GB SanDisk CF, a card from the last generation with a fast read and write procedure. When this older card is used it is clear that the differences between write and read times do exist. It is recommendable to have yourself informed when purchasing a memory card, and to pay attention to the guaranteed speed of the memory card.
Considering a 512MB memory card:

The DiMAGE A2 uses a Li-Ion battery (NP-400) and is recharged through an external adapter. The battery compartment is shut properly by a firm lid. The camera can be equipped with an optional handgrip. This grip offers room to some two NP-400 Li-Ion batteries or six AA batteries. In practice the user is well-off for one battery but if there are circumstances like a holiday when there is no energy available to recharge the battery it might be handy to have a second battery and use it as an extra. Performance of the battery is fine to excellent. In the past the first generation DiMAGE 5/7 cameras were energy consuming. But this has changed for quite some time now and the energy consumption of the DiMAGE A1/A2 cameras is on an excellent low level. Some functions like the Continuous AF and the Anti-shake have a raised energy consumption but despite that one can count on a minimum of 2,5 to 5 hours of energy which in practice means many images. A good energy-saving function is the possibility to activate the electronic viewfinder when the sensor detects the eye.
