Hi,
I'm kind of a newbie in Digital Photography and am wondering about the CF's memories' speed. I own a Kingston CF 256 MB card that doesn't really say anything about its speed, but the camera's (Canon A95) performance is real good, in comparison with others.
That's enough background, the point is: is there any REAL difference using a better (eg, SanDisk Extreme III CF) memory card?, does it worth to pay a li'l more for it?
Another question I have is: how can I find out my memory card speed?, like I said above, all I know is that it's a Kingston with a 256 MB capacity and it's orange

Greetings to everyone, have fun.

As far as I'm concerned, the whole field of which card works best with what camera is uncomfortably close to voodoo. The same card can work beautifully with one camera and be a train wreck with another.
I wish that there was a testing facility that would run bench tests with hundreds of different cameras using, say, a few dozen different cards. That's about the only real way to answer the question of how does a particular card work with a particular camera.
This has been done, though in a very limited way, on www.dpreview.com, but they only test DSLR's.
Minus this kind of information, you're pretty much stuck with manufacturer's recommendations and user forums for the kind of camera you have to hear about what other owners of your camera are using and how it works for them. The camera manufacturer's website will sometimes tell you whether the camera can take advantage of the speed features found in higher-end cards.
This seems to be one of those questions that Google only seems to make more complex.

See if there are any identifying codes on the Kingston card and check out their website. You might get lucky and find something in a data base that would tell you the technical specs of that card. If not, and they give you the option, write an email to their tech support and give them all the info' you can about the card and ask them.
Good luck!

There is a great deal of difference in card speeds, and yes, the Sandisk III is one of (if not the) fastest--but your camera may not be designed to take advantage of the speed, so buying one would be a waste of money in that case. You should google for some data on what cards work best/fastest with your particular camera.
Example: my Olympus E-300 has a firmware update that allows it to take full advantage of the Sandisk III's speed, and it really makes a difference in sequential shooting, but the earlier and more expensive Oly E-1 cannot use the additional speed because its firmware can't handle it. In short, don't buy more expensive/faster cards until you're sure what your camera can do with it.

To find out the speed of your card, either go to the manufacturer's website, or try shooting the maximum number of sequential test shots and time how long it takes to clear the buffer (on most cameras, the length of time the buffer light continues blinking). If shooting jpegs, be sure that the camera is locked down to a tripod and the image/lighting is identical in all shots, or else the file size will differ and throw off the measurement. Ideally, shoot RAW for the test, since the RAW size should be identical for all shots. Divide the total MBytes by seconds required to learn how many MB per second the card/camera combination can transfer.

Yeap,

my digital rebel xt needs fast cards. they us sandisk ultra II's or faster. other wise the computer can only write out the picture as fast as the card will accept the data. they will use the extreme III cards too. but, yeap, it's what your camera requires.
