Yes
Ive searched and searched for an answer to no avail.

So, if i get a 16gb cf card for my 7d how many pictures will i be able to fit on the card?

A friend of a friend, sort of thing. Has said he can get me a sandisk 16gb cf extreme pro card for £95 as a one off but said would that be enough?

Maybe some one here can tell me how many shots in raw or jpeg at full quality can fit on a card of this size?

Depends on the size of the image and whether its RAW or not. I use a 8GB card and get 200 Raw plus large JPG. If I just have it in large jpg its about a 1000. Hope this helps!

Yea that helps, knowing some thing can store 1000 images in large/high quality is good, i dont think i will shoot at large image size all the time though.
Last thing £95 is a steal, aint it?
 
Have a look at the current file sizes you are getting from you 7D. I would guess they average out at around 22-23 Mb which means around 720 images give or take
 
Only have a little 2gb at the mo, it says only 1.6gb storage. I know some of the storage has to go to workings of disk and deletion. Plus i think this is a duff disk i have at the mo.
 
I find that the number of pictures I can get on a memory card is determined by how many I'm prepared to lose if the card goes belly up :-)

This is a very good point! IUnless you are in some sort of pressured environment and have to bang of 100's of shots in a short session I would buy two 8's!

Agreed,

Stick with 4Gb or 8Gb cards and buy a few.
 
I just use 8gb micro SD cards (from phones) and they work fine in my D5k, get about 500 Raw.

I use 8GB card and get 250 Raw plus medium jpeg.

Useful to have a 16Gb card if you want to shoot some hi def video.
 
This is the dilemma I'm facing. I don't like to have all my eggs in one basket, so the largest card I've got at the moment is 4GB. However, since moving to the 7D I'm leaning towards 8GB, but I'm also wondering if I should go for 16GB due to the Video. Decisions, decisions...

Either way, Sandisk cards on Amazon seem good value at the moment.

I shoot with 16Gb cards in my 7D and 1DIV. Generally means I can get through a day without needing to open the camera and risk dropping cards whilst trying to change them in a blizzard or heavy rain. Its amazing how easy a CF card is to lose when dropped...

Most of the time I don't get close to filling them but the reserve capacity in nice to have.

It's strange, isn't it. It's such an obvious question, you'd think Canon would say something about it in the camera's user manual.

But wait! What's that on page 59? :bang:

but how often do u off-load your pics??? i would do it every night. make sense if you do it once a month but they used to say this when 2gb cards come out, get 5x 512mb cards, and it will keep going, just get the 16gb and have a spare. if the shot are 100% un-losable upload them to a laptop while your out and about
 
I'm not a professional, so I suppose you could argue my pictures aren't worth anything. But I'd still be gutted if I lost 16GB of family pictures after a day out. Taking a laptop out with me is not an option. Yes, I download all my pictures at the end of the day, but that doesn't remove the risk of card/camera going belly up moments before and losing the lot. The loss would be reduced by using 2x8GB, for example. So it's definitely a consideration, whatever your circumstances.

If I were shooting only pictures, then I think I'd have ordered some 8GB cards already. But as the 7D can do video as well, then it'd also be nice to have the extra capacity of 16GB for that.

I think 8GB might be a nice compromise.

There are cameras out there that can take 2 cards, aren't there? How do they work? Could you record pictures to one and video to the other, for example?

I have a 16Gb, it states 610 images at ISO 100, generally I would get around 700 or so in RAW only (not really seen the point of RAW+JPEG, as I can browse the RAW directly).
I prefer a large card, probably for a stupid reason. I prefer not to swap cards, and risk debris getting into the system, where I cannot see it.
At the end of a day, I plug the camera into a device (PC, laptop, whatever) and download all images via USB. I then use the reformat option to blank the card.

Naughty Stewart :):):):):)


John, get the 16GB card. £95 is a great price (assuming it's not an Ebay fake). And don't worry about keeping all your eggs in one basket. It's much safer than trying to juggle several baskets of eggs. CF cards rarely go wrong. I've been using them for over 15 years and I've only had one go wrong - and that was my fault because I pulled it out of a PDA while data was being writ to it.

I have, on the other hand, lost cards - once because I put it 'somewhere safe' in a hurry (found it a few weeks later) and once when it must have fallen out of my bag. With a single, large card (I use 32 GB) the only way I can lose it is to lose the camera - which I hope I'd notice;)

Wow is it on page 59???
Its nice to know that some one of the modern male generation reads some thing called a "manual".
 
I use the 16gb Extreme Pro and that's a great price if it genuine. Very fast cards indeed, and if you intend on shooting video as well you'll want lots of storage. I've never had a CF fail (yet) so don't worry too much about the eggs in a basket thing.

Make sure you get a Firewire 800 card reader to make the most of the transfer speeds to your computer. It's VERY fast!
 
I must be unlucky then. At the beginning of this month I had a brand new 7D go snafu and take the card and it's contents with it. And a couple of months before that my 40D went snafu and did the same.

I was thinking if i need to shoot quick in anticipation of a shot happening that i want, 8 pictures a second on write to the card is going to get used a few times. If a card slows it down then i would have lost out for the sake of £40.

Also to shoot 1080p hd video as and when i might use it, although i think i will be taking enough pictures to make a movie.

IF 60mbs is going to be enough from peoples views then i will save the £40 for some thing else, but if its better off being a 90mbs then so be it.

Im a novice, so advice is always welcome.

The extreme @ 60Mbs should be fast enough for HD video without a problem. I think the 7D buffer will run out before it writes to the card anyway....

I'm so glad I listen to all the folk who told me that when I bought my 30D, and 2 x 1GB card as now I've upgraded to a 1D they hold a huge 40 images and are more or less a waste of time :shake:

Get a 16GB, your more than likely not going to fill it, but in a few years time when we are using 50megapixel cameras it will still have some use, unless of course your an old film user and think 36 shots before a refill is how it should be.

That's the advantage of the very fastest cards, they empty the buffer quick enough that it makes it harder to fill the buffer in the first place.

Like you, at the end of every day ... but that can still be a hell of a lot of pictures :)

I have a couple of 8GB cards (plus a slew of 4GB ones) and have on one ocassion filled both in a single day. The only card I've had fail to date was a 8GB Sandisk extreme III and whilst Sandisk replaced the card without question they couldn't recover more than a handful of the pictures.

Here's a posting about card speeds and the 7D.

This was my conclusion...

So, before you splash out on a 60 or 90 MB/s card ask yourself some questions -

* Do I often fill my camera's buffer?
* Do I ever fail to get a shot because I'm waiting for the 'Busy' light to go off?
* Do I have a high-speed card reader?

If the answer to any of those questions is 'Yes' then a high-speed card may be for you. If the answers are all 'No' then you'd probably be wasting your money.

Erm, never seen the busy light and i dont want to specially if i miss the shot i want.
Yes i have a firewire card reader.
I dont know what the capicity of the cameras buffer is.

I take it these are Canon cameras :D :exit:


I keep my card in the camera and after every outing i transfer them to my pc via the usb lead. I then format the card in camera. Some say you should use a high capacity card to save swapping and damaging pins in the camera or the cards. I haven't had any problems as yet and usually don't have to swap cards as I can get over 360 RAW on an 8GB card but the spare 8GB is there if need be.

You'll only see the busy light if you shoot a lot in burst mode.

FW400 or FW800? 400 is just a bit faster than USB2, around 40 MB/s. 800 is twice as fast - definitely worth having a FW reader if you've got FW800.

If you shoot raw it's 16-20 shots. If you shoot jpeg then it's virtually unlimited.

Don't ****ing listen then :razz:

The point is, if you have one large (16Gb or 32Gb) card and either; fill it up in one session or don't clear images off it until it is full then you are risking losing hundreds or thousands of precious images.

Split across several smaller cards (and nobody mentioned 1Gb cards) you are less likely to lose shots due to loss, failure or damage of one or more cards.

If you are really touchy over having a couple of 1Gb cards that are worth 2 or 3 quid and are now of little use then you shouldn't be buying camera gear as it all depreciates and we all end up with some 'surplus' items that we no longer have any use for.

But, according to the 'eggs in more than one basket' theory, you should be using 1GB cards - or smaller. That way, if a card should fail, you only lose 40 images instead of 150. I'm sure loads of us have old cards we don't use, perhpas we could donate them to you? I've got a few 64MB cards that would only result in the loss of four images if it should fail (although it still seems to be working OK after 15 years).

Now you're just being a **** :cuckoo:

I'm glad you have never had a flash memory card fail resulting in lost images, the reality is that they can and do fail, sometimes the images can be retrieved other times they are gone for good.

I don't actually give a flying **** if anyone else loses their images - buy a 64Gb card, fill it up with your most precious memories and then lose it - see if it bothers me one bit :thumbs:

I mentioned 1GB cards :)

hollis_f is right we should be using the smallest card possible just to be on the safe side, your saying it's OK to lose a few hundred images of an 8GB card if it fails, but not to lose a few more hundred of a 16GB card. At what point is even one precious image worth losing.

My original point was that as the biggest card sizes double then the safer than sorry size cards also double. Over the years I've had digital the argument has gone

2 x 1 and not a 2gb
2 x 2 and not a 4gb
2 x 4 and not a 8gb
2 x 8 and not a 16gb
2 x 16 and not a 32gb

and so it goes, when 1TB card are really available I guess you'll be shouting no get 2 x 512GB cards just to be safe.

I have the 800 one, it came in the laptop i got.
I dont know if i will shoot in raw or jpeg, i will make my own mind up but most prob end up doing what everyone else will be doing.

Ive looked at the lexar 600x 16gb, they are £12 cheaper than the sandisk ones. But is this a whole other arguement about which is better, sandisk 600x or lexar600x? There is only one way to find out FIGHT............!
