Some questions about Memory and 40D.

I soon will buy a Canon 40D even though im lowbie knowledge about it. Do you guy have any tips how to perform a test out that it is a flawless Camera without any defective? Like the sound that it make or dead pixie on LCD or Coler correction? Do you think latest firmware solve the problem?

I need some advice about which memory I should get, like which brand? When I check out a brand name ScanDisk and it have Extreme and Ultra I dont know which to get:
ScanDisk - Extreme III
ScanDisk - Ultra II
Im buying this camera for a vacation going back to my country and took some picture do you prefer I should buy 2x 2GB to make sure if one memory got defective or 1x4GB Memory?

unixsac,
Welcome to the POTN forum

When you get you camera just use it as you intend to and you should see if there are any problems with it. I haven't had any problems with mine with months of usage.

As for memory cards, I personally use SanDisk Ultra II cards and have no problems at all with any of my cameras, but Ultra II or Extreme III will both work with your 40D. I also agree with having two 2.0gb cards is better then one 4.0gb card.

Enjoy your new camera

Calumet Photographic has a special on 2GB SanDisk Ultra II CF cards right now: 2 for $29.99, which is a pretty good deal. If you're worried about your cards failing, after you've filled out the card, find a photo lab that can make a CD backup for you. I personally haven't experienced a failed card, but you just never know. Don't forget to get a couple extra batteries as well. Sterlingtek is highly recommended here.

I think you shouldn't worry about the camera not performing all it's functions out of the box. Mine had the latest firmware, and it's still working perfectly.

I have a pair of Sandisk 2GB Ultra II's and an 8GB Extreme III with the 40D. The only difference I can notice is the extra capacity of the 8 GB.
