How large a compact flash card can the 7D take?

With the announcement of the 128GB compact flash cards

http://www.dpreview.com/news/1001/10011904siliconpower128gbcf.asp

early this year I began to wonder just how large a compact flash card the 7D can take. My largest card is only 32GB and I cannot find any information about card size on the Canon web site.

Has anyone used a 64GB card in the 7D? Does anyone have an interest in the 128GB cards?

Re: How large a compact flash card can the 7D take?

The largest CF card, according to the current standard for Compact Flash cards can only be up to 128Gb. That's because the addressing is only 28 bit.

All cameras that support cards larger than 2Gb CF cards automatically support the 128Gb cards. Please note that this is not related to the speed.

I think that I've included enough techno-babble.

Why would you want a card that big? I recently picked up a high-speed 16GB card, and even shooting raw that's the largest I feel comfortable with. Besides, with 128GB being new they're also going to cost more per GB.

Re: How large a compact flash card can the 7D take?

We tried the MONSTER 64GB and it worked great in our 7D for years.  This was fantastic since occasionally the 16gb would fill up with out noticing especially when shooting non fiction-off the cuff-sort of shots.  Or if we had a single shooter that was also interviewing the subject, he might miss that the card running out, if he was not watching the monitor every moment.

The cons are - if you format it in the camera it seems to mess it up sometimes and you dont get the full capacity.  We had to use a swiss knife utility on pc to reformat the card properly to resurrect the card once.  It seemed to work fine if we reformatted and emptied the trash each time on the mac. NOT the camera.

Also, it locked up on a transfer once, and when we rebooted we lost the card forever as well as the ENTIRE DAY of shooting, the upside of a smaller card is that you loose more when they go bad.  It seems all cards may go bad at some point after reading about the most expensive cards, they often go bad as well.

Use them wisely.

Yes the 64Gb works but there is one restriction according to Canon. Can't use it for updating the firmware (the largest size is 32Gb).

I use a few 32Gb and I would be interested in the 128Gb once the price goes down. For trips, puppy and birding.

I noticed this is an old thread too, but I'm compulsively forced to reply... can't... resist... I use a pair of 1000X 128 Gb cards for traveling with my 7D when I don't want to lug a computer around. I can shoot for weeks and not fill those cards up. Never once had any problems, and they're the third-fastest CF cards made, according to Rob Gallbraith.

On principle I do not use cards bigger than 16G, and I shoot only in RAW.  I recently had a new 8G Sandisk 60mb/s card lose its memory chip and I could not recover any images and lost a three hour studio shoot as well as other client images.  I could not even format the card, it was that dead.  I use smaller cards in the event of something going wrong you at least limit the quantity of images that you could lose to what you can get on an eight or 18G card.  That is my penny's worth!!

Each card has interface electronics and of course the physical connector - so more cards means more points of failure. Changing cards more frequently means more wear and tear on the pins in the camera. Cards which are not in the camera are more likely to be lost or damaged.

And then there's the shots you potentially miss when you get that 'card full' message and have to fumble around finding a fresh card, swapping it over and putting the used card in a safe place. Shots missed when nothing has actually gone wrong - how frustrating is that?

So for several reasons you are much less likely to have a problem if you use a single large card.

I understand the fear of "losing everything" with larger cards but that has to be weighed against the greater risk of failure/damage/loss with small cards. I'm 100% satisfied that one large card (plus backups, often your older smaller cards) is the way to go.

Steve I agree with all your points, I am thinking of going to the 5d for the sake of an extra card slot!!:-)

Re: 2-1/2 year old thread... still relevant

If you were replying to an old thread asking if they were going to come out with monitors bigger than 15" or if there would ever be a successor to the 20D, that would be a waste of effort. But questions about memory card sizes still come up and therefore this thread is still relevant and worth a response.

Oh good grief.  I've been using CF cards for 14 years, and have never had a failure because of wear & tear.  The one time a card failed it was fairly new, it was simply an electronic failure on the card.  Kingston replaced it.  As for losing them, the reason I prefer CF to SD is because of the size.  I have a card wallet where they're always accessible and easy to find.

And then there's the shots you potentially miss when you get that 'card full' message and have to fumble around finding a fresh card, swapping it over and putting the used card in a safe place. Shots missed when nothing has actually gone wrong - how frustrating is that?

Never missed a shot or had to "fumble around" trying to find one.  A 16GB card holds 600 raw images.  I don't use a machine gun approach to my shooting, and I know when the card is getting full so I change it at an appropriate moment.

So for several reasons you are much less likely to have a problem if you use a single large card.

I understand the fear of "losing everything" with larger cards but that has to be weighed against the greater risk of failure/damage/loss with small cards. I'm 100% satisfied that one large card (plus backups, often your older smaller cards) is the way to go.

That's fine.  I prefer smaller cards.

you can also put an SD-card in there; preferably with an adapter to it..

Re: How large a compact flash card can the 7D take?

I have a 32 gb 30 mb and a 32 gb 60 mb . 4 - 16 gb 30 mb .

I have found the only time I use the 32 gb - 60 mb is for bursts .

Shooting raw +jpeg you can fill the 32 gb , but it takes a while to down load from camera .

I really don't see a need for anything larger than 32 , but I felt the same way with 16 gb on the XTI .

My opinion is 2 cards are better than one = 2 - 16 better than 1 - 32 . I would buy a faster card - like a 16 gb at 60 mb rather than a 32 at 30 mb .

Sorry , kind of wandered off subject .
