Canon EOS 30D | Digital Camera Review | Storage and Energy
With the Canon EOS 30D, Canon have decided to stick to the BP-511/BP-511A Lithium Ion battery, which Canon users will undoubtedly recognise, and is a familiar feature from the Canon EOS D30. Those who are making the change from an older body will thus be able to keep using the old charger and batteries without any problems whatsoever. It is logical that the Canon EOS 30D, just as almost every other D-SLR, uses the CompactFlash memory cards. These cards seem to be available on virtually every street corner, at an attractive price and in many capacities. This doesn't change the fact that it is always wise to invest a little extra in a fast and stable memory card.
Canon EOS 30D - 1GB CompactFlash memory card
Just as its predecessor, the Canon EOS 30D features an eight Megapixels image sensor. In RAW, it produces images of approximately 7 - 9MB in size, depending on the ISO value, whilst in the highest quality JPEG, the images are approximately 3,6MB in size. You will need a memory card with a reasonably large storage capacity, but there doesn't yet seem to be a (real) need for the 4GB cards. A memory card of 1GB will suffice nicely, as is shown in the table below.
Considering 1GB of storage capacity:
RAW - 3504 x 2336 pixels - 8.7MB - 110 images
JPEG large - fine - 3504 x 2336 pixels - 3.6MB - 266 images
JPEG large - normal - 3504 x 2336 pixels - 1.8MB - 534 images
JPEG average - fine - 2554 x 1696 pixels - 2.2MB - 450 images
JPEG average - normal - 2554 x 1696 pixels - 1.1MB - 884 images
JPEG small - fine - 1728 x 1152 pixels - 1.2MB - 784 images
JPEG small - normal - 1728 x 1152 pixels - 0.6MB - 1522 images
Resolution - RAW + JPEG large - fine - 78 images
Resolution - RAW + JPEG large - normal - 90 images
Resolution - RAW + JPEG average - fine - 88 images
Resolution - RAW + JPEG average - normal - 98 images
Resolution - RAW + JPEG small - fine - 96 images
Resolution - RAW + JPEG small - normal - 102 images
Canon EOS 30D digital reflex camera - Buffer
The internal buffer of the Canon 30D is large enough to store 11 RAW or 30 JPEG format images, at least, according to Canon. In practice, we saw that, when using JPEG format, you are easily able (provided that you using a fast memory card) to fill a 1GB card. A small hiccup during the storing is the only thing that reminds you of the fact that the camera is working at full speed. In RAW format, shooting 11 images sequentially is indeed the limit, and this will require a little bit of patience. The Canon EOS 30D is able to store the images quickly onto the card; in combination with a SanDisk Extreme III CompactFlash memory card the entire buffer is emptied within half a minute. This is mainly thanks to the unprecedented DIGIC II processor. A fast memory card is of course advisable, I would recommend a card with a minimum speed of 10MB/sec. A faster SanDisk Extreme III memory card particularly offers advantages when shooting a lot of series and working in RAW format.
Canon EOS 30D d-SLR - BP-511(A) Lithium Ion battery
The well-known BP-511(A) Lithium Ion battery can again be found with the Canon 30D. An excellent choice, as it increases the compatibility between the different models. The provided information claims that when the battery is fully charged, you are able to capture over a 1000 images at room temperature. In practice, and in a colder working environment, we were unable to achieve this, but approximately 500 images should not be a problem. Naturally, this greatly depends on how the Canon EOS 30D digital SLR camera is used. If you are shooting in sequence, you will be able to capture more images than when there is a longer pause between your shots. In comparison with the EOS 20D, the EOS 30D is able to capture more images, and with over 500 images per battery load, you will pretty much be able to keep working without interruptions.
Canon EOS 30D digital SLR - BG-E2 battery grip
Those who require more than the standard amount of power, or prefer not to depend on a Lithium Ion battery, can invest in the optional Canon BG-E2 battery grip. Besides an alternative and extra power source, the battery grip offers a vertical shutter release button and several extra buttons, which greatly benefit the easy of operation. The BG-E2 holder can fit two Canon Lithium Ion batteries, or 6 AA batteries through the delivered holder. The AA format batteries are available on virtually every street corner, which makes them a cheap and stable alternative!
