Anybody want tomake a educated response to this image(s)??

2nd frame of a five frame burst. the first and all others are clear and sharp.

specs are roughly - iso400,1/50sec,f5.6

This is about the 15th or so shot out of a new 20D.

Flash card corruption!
(ie data on that frame is corrupted)

What kind of CF and how fast was it?

NHL-

Thanks for the quick reply. A Lexar 4x, 1 Gb. It has worked flawlessly in my 300D for about 3 months or so.

I will be updating firmware tonight. I understand this is one of the "fixes" that Canon has worked on.

I took a little over 220+ shots on the card and all others are right on. I did notice that it took quite a while to come up in ACDsee.

Just my luck to get a finicky new camera. !!

Yeap... that was my suspicion. The 20D can write very fast while your regular CF card is kind of slow it down!
-> this happens in PC too with slow memory buffers in Video capture cards.

BTW 40x and 80x 1/2G CF cards are now incredibly cheap at less than $100!

As I mentioned this anomoly happened AFTER about 20+ shots and did not reoccur for the next 150+ shots. I have to believe that they (Canon) must understand that there are a ton of not-so-high-speed cards in use out here.

The burst speed is amazingly fast - so the 'glitch' is in how the buffer download speed is directed. Can't imagine I will have totoss outmy two 1Gb cards.

I will put up the test results as soon as I upgrade the firmware.

I don't think your problem is CF corruption specifically, but more likely camera-to-card buffer dump/communication. The 20D has had early reports of miscommunication with some CF cards, so I don't think (necessarily) that you got a finicky camera. The new firmware is supposed to address this issue I believe, so it is probably more widespread than the occasional finicky camera.

Updated firmware last night.

Banged off a series of bursts 4+5+7+5 - All shots worked fine and transfer was quite fast.

Using a Lexar 4x 1Gb card.
