When you look up the 7D on the B&H website, under accessories it recommends the Sandisk extreme IV compact flash card. I've had good luck with sandisk using my HF100 and GH1 so I'm going this route.
B&H are sold out but buy.com has them slightly cheaper, with tax and shipping they are $93
There is a $60 rebate offered by Sandisk which is valid if you buy this card before sept 26 and mail in the rebate before oct 12.
Rebate can be downloaded here (http://www.bhphotovideo.com/bnh/controller/?O=home&A=getRebate&Q=&sku=443594&ic=SAE4CF8GB&is=REG)
If this works I should have a CF card for $33
Hope this helps you all. Any other deals, post em in this thread !
EDIT - thanks finster (post 9) this rebate doesn't work with buy.com instead see stores listed on the pdf

What size Davis? Wait I guess 16GB cards since those are the ones with the $60 cash back and the largest IV.
Will 32GB cards be compatible with the camera?

I'm a bit confused by this rush for speed. IIRC, the 133 Kingston is plenty fast for 7D video capture.

Canon manual says 7D tops out at 8MB/s. Lets say they are wrong and overestimate to 10MB/s.
The Kingston 133x card transfers at an estimated 20MB/s. Even if that is an overestimation, it is twice the speed necessary for video from the 7D.

Be sure to read the fine print! I don't see buy.com listed as a "qualified retailer" for the $60 rebate.
Which one are you seeing for $93??? I can only find the SanDisk Extreme IV on buy.com for $164.
Edit: Oops - I see you were referring to the 8GB card. I was looking for the 16GB card.

Well, I bought them months ago for my old DSLR and I don't remember where I got them exactly. It was some eBay seller (You have to be careful though as many companies sell knockoff Kingston cards) back when eBay and live.com (now bing) had 32% cash back which made the cards even cheaper than the ~$70.

The 7D codec is the same as the 5D Mkii right? So we need a class 6 right? Can't do like the gh1 with a class 4?

The 7D and 5D MKII use CompactFlash (CF) Cards, which are rated in terms of an "x" rating, linked to a MB/s write speed.
The "Class" rating system is used for SD and SDHC cards, which are incompatible with the Canon DSLRs in question.
The Canon 7D manual has specified cards must meet or exceed an 8MB/s write speed. That means anything faster than a 66x CF Card, which provides 10MB/s, should work. However, some cards do not perform to specifications and so it is generally wise to add in a bit of a buffer. Users have reported no problems with 133x (20MB/s) cards in terms of dropped frames under normal operating conditions. Others prefer stepping up to faster (and consequently more expensive) cards for perceived brand reliability and performance.

I own 4 of the 32GB kingstons. Absolutely great. Something that should be noted is that the real world transfer speed of the 133x 32GB kingston is greater than both the 8GB and 16GB of the same line. After experiencing that myself I searched the internet and found that others had found the 32GB similarly faster than expected given the price point.

Looks like the 64GB card really is shipping as of TODAY and for "only" $250: http://www.buydig.com/shop/product.aspx?omid=103&ref=froogle&utm_source=Froogle&utm_medium=cpc&utm_campaign=SDCFXP016GA91&sku=SDCFXP016GA91
So within the next month there should be a small drop in price for this card, the 32GB, and 16GB. Though it might take a little longer... might be best (as always with memory) to buy at the last possible moment so it arrives together with the rest of the gear.

Sometimes a project needs and deserves the recording time... however with the max clip duration that this camera imposes is simply doesn't apply here. Might as well make that two second stop a 10 second stop.

Anyone worried about the potential problem with the SanDisk Extreme 3 cards and the 7D? There's been talk of trouble with those cards and the 5Dii here: http://www.dvxuser.com/V6/showthread.php?t=167750
and here: http://lightingmods.blogspot.com/2009/06/tip-canon-5d-markii-video-locks.html
I just ordered a few and I'm a bit worried about it. I'd rather not find out the hard way after my camera arrives (and I can no longer return the cards) that they don't work properly. Perhaps I should return them for the Kingston 133x cards instead? Thoughts?

I think it's Sandisk Extreme IV that is being recommended, not Extreme III, well at least that's what's on the B&H site.
I'm not sure why there is so much buzz about CF cards with huge capacity.
Sometime its better not to have all your eggs in one basket if you know what I mean. Have a few 8 or 16 gig ones and use them in rotation.

THIS!
16GB is a ton of data. An absolute ton. Its just getting to the point where we're comfortable with tossing this amount on a single card...and I'm still weary. I'm confident in the cards holding up, but I've physically lost cards before. 64GB of data on something the size of a half dollar is unnerving!
I think it's Sandisk Extreme IV that is being recommended, not Extreme III, well at least that's what's on the B&H site.
Um... hit the "See more memory cards" button on the B&H site and you'll see Extreme III card listed as well. The WAY more expensive Extreme IV card is featured though (imagine that!).

So, given the lack of responses to my SanDisk question, I guess there isn't much fear about them working? It seems the research I've done is that the problem is inconsistent at best. Perhaps there was a batch of bad SanDisk cards? Dunno.

I have the Kingston, and it works fine. Seriously, there's no need for SanDisk and their crazy speeds, unless you do burst RAW photos.
Some people are paranoid about reliability and compatibility, so they decide to overpay for SanDisk. But remember that there are bad SanDisk cards, too. And people have already found some.

Actually, the larger capacity cards offer better value in terms of price per GB. Smaller capacity cards will go through more write cycles and thus should theoretically wear-out faster.
If you're that concerned about losing all of your data on the card, then just download the files after each set-up. You don't have to reformat the card every time (and you shouldn't); just copy the new files.

ydgmdlu
09-21-2009, 06:20 PM
May lose bit rate. Easiest way to know for sure is to do some tests.
I guess I can go with the kingstons for now until someone does some tests. They are cheap enough and I can always use them strictly for photos if they turn out to be not ideal for video

From the new GH1 firmware thread:
Sorry but from a engineer's point of view I can't help but laugh about this card-mud-relationship theory :D
The firmware will not measure card throughput and dynamically adjust the encoder to produce optimal results. This is even better than the CMOS fixed pattern burn-in theory :grin:

I find it pretty funny that so many of you are talking about the super high speed disks for tons of money. Having a faster CF card, other than a little buffer for safety, provides absolutely no benefits. If the camera writes at 8 MB/s and your card writes at 10MB/s your fine. Paying extra to write at 45 MB/s?
I'm going to try these Kingston 133x 16Gb for $39.99 each. They should be plenty fast enough.

Yea, UDMA for that I would imagine. But I wish Canon would clearly draw the distinctions between what is needed for video recording and what is needed for the other functions. These general all-inclusive requirements are needlessly confusing.

Real world use has shown that UDMA is not a requirement, but there are theoretical benefits to using these cards that I haven't seen anyone manage to disprove yet -- should also be noted that outside of the statements by the Canon rep, no one to my knowledge has proved or documented problems with using slower cards, outside of the inability to take stills while shooting video on occasion.
Unless we get into some kind of conspiracy theories about backroom payoffs between memory companies and this Canon rep (who is not a small fish), there is little reason for him to advocate for UDMA unless he believed (or, as he stated, saw) a reason to using UDMA enabled cards.
For this reason, if I was on a paid gig I would want to be using fast UDMA cards just to be absolutely sure my client was getting the best image out of the camera. Specifically I would be using UDMA no question for weddings as well, for the ability to comfortably shoot a still during video. Are they necessary? Obviously not. Is there a peace of mind vs. cost of expensive memory debate that every shooter can legitimately have with themselves? Yes! And that's for you to decide.
For personal projects I'll probably get a 32gb relatively no name, for paid work I'll use speedy name-brand UDMA cards and wait for deals to accumulate a nice staple of those.
J Davis
10-11-2009, 04:12 PM
The older sandisk extreme IV's are 40 MB/s the newer ones are 45 MB/s both are UDMA. The label on the older one doesn't say UDMA but the FAQ on sandisk website confirms that it is.
SOURCE: ---> link (http://kb.sandisk.com/app/answers/detail/a_id/262/session/L3NpZC9QZDRfcGFLag==)

Canon's product manager has drawn that line -- he said you need UDMA.
And that is hogwash from what I can tell. The business my family owns is a security consulting firm and one of our clients in Frys electronics. Being on good terms with the managers there, I was able to get a few different CF cards for testing on my 7D. I already had a couple 32gb Kingston 133X non UDMA cards and we tested a couple non UDMA 150X no name cards and two UDMA cards, Sandisk Extreme IV and Lexar Pro.
Didn't bother with stills because the issue there only seems to be with high FPS continuous shooting.
In video mode, there was no discernible difference in any of the stuff. No more artifacts or noise. Nothing. I think if you can afford the UDMA cards, go for it...but if price/capacity is more of a concern I don't see any reason to bother.
