Raw Images using 7D
I do quite a lot of motor sport photography and I have always been in the habit of shooting raw using my 40D. With a 4GB card I was able to get around 300 images.
I have just noticed on my new 7D using a same 4GB card and I see the maximum is 150 images.
I also use trhe continuous mode so it would appear I am going to be kept going changing cards and at the same time investing in more cards as I usually shoot around the 1500 images on a good shoot. Has anyone any views on this or advice.
Cheers

If you're planning to buy more cards, why not switch to 8GB cards? That will put you back at the same number of images that you were getting on 4GB cards with your 40D.

18mp images take a lot of data. I was using 8gb cards and just this day went to 16gb. with my two 7Ds.

Thanks ever so much for all the input on this subject. I have numerous Sandisk Extreme 4gb 30mb cards and the reason I went for the 4gb was in case one of the cards failed. However, I am so pleased to say I have never had a failed card. Having said that I will now probably get one.
I will go for the Sandisk 8gb 60mb cards just in case one of them fails. Although it would be great to use a 16gb knowing I could get around 600 images without changing the card. I do know from past experience I have lost many a good shot on a card change over.

Why wait until a card is chocko full? There's gotta be a break or a few in the events, change your card to a fresh one when the card that's in doesn't have what you estimate you'll need to complete the event, even though it's not full.
I have a Sandisk Extreme 8GB 60mbs UDMA, and it is very greasy.:D

For most people, after you buy your first camera this isn't a choice, but the way it works out anyway. For my first DSLR I bought a set of 1GB cards 5 years ago, then 2GB and 4GB as prices fell. Then, when I got the 7D, I needed to buy 8GB cards. But as is probably the case with most people, buying big new cards did not mean stopping the use of my older cards, which means that as a matter of course, I have a mix of large and small cards providing a range of options for volume or safety.
Thanks Neil. I have just ordered a Sandisk Extreme 8gb 60mbs and I take it when you say it is very greasy you are pleased with it!! Should I find a big difference between this card and the 4gb 30mbs I have been using with my 40D. If this is so I am beginning to think I will be needing a few more 8gb cards.

Thanks Awais I follow you quite a lot on Dgrin and I know you are enjoying your 7D by the remarks you have been making. I don't consider myself in your league but I am sure I will enjoy my 7D once I get all these finer points ironed out from my 40D which I would recommend to anyone.

On a 7D, you can shoot mRAW and get almost twice as many files per card. Unless you really, really need 18MPixels, this might work for you. I shoot my family snapshots in mRAW, and only use the full size RAW when I need it. Just a thought, and cheaper than replacing all your CF cards.
Don't any of the previous posters ever shoot mRAW?
I think one 16Gb card will hold a whole days worth of mRAW files, too. My 7D shows 888 mRAW files on a 16Gb card, so maybe you'll need two cards for 1500 images, but that is a lot better than trying to juggle 4Gb cards.

Thanks Pathfinder, the prints vary in size. I don't really need to use 18MP. What you have said is certainly food for thought and I will change to mRaw and give it a try. I can forsee juggling 4gb cards would create a problem and the 8gb card I have ordered is £38.99p so to order more would be damned expensive.

I've got a 40D, but I'm seeing a few comments from 7D owners that a fast 8GB card is good with it.

Now I have a few fast 8Gb and 4gb sandisk extreme's for everyday shooting, (about 30gb in total) and 3 very cheap (the cheapest I could find, trancend and adata) 16gb cards for when I'm going away and need extra storage or am shooting video.
I've never had a card go bad on me, nor have any of my shooting buddies, but I've certainly missed moments when the card fills up and you don't realise it. So I suggest buying the largest card that's still economical (the 32gb's were still overpriced last time I looked)
And what about the shots you (= me) miss when you don't have a card in the camera in the first place?!!!wink:D

Turning off the option that lets you shoot without a card in stops that from happening accidentally. But I keep my old cards (the 1gb and smaller) tucked away in the lining of my camera bags for when I forget my normal set of cards.
Yep, James, I'll get round to that eventually!:D

Nope...paid for 18mp and I gonna use 18mp. You just never know shooting wildlife when you are going to want/need it.
That would be like going out with a 70-200 instead of a 100-400 and hope you get close enough.:D
Just received my 8gb card and it certainly works well in continuous in the 7D. I am awfie tempted to purchase a 16gb but I would be terrified it packs up on me so I may take Pathfinders advice for the time being.
Tell me Ric what is the exact benefits from shooting Raw and mRaw. I know the size of the pixels are different but is the difference only for the size of prints at the end of the day or does it show in the quality of the photo? Hope I have made myself clear.

In jpg, I get about 2000 shots per card with the 7D, 1800 with the 5DMKII.
They aren't real fast, but they have been very good to me.

Thanks for that Dave.

More data in full size file allows for more flexibility in composition via crop while processing image. This may not matter to you for what you are doing...it does matter to me.:D
Thanks for that Ric I appreciate what you say and I am sure you are right it won't matter to me taking photos of motor rallying through the forests etc etc.
