Memory Usage?

I am about to buy my first DSLR camera. I am pretty much set on the EOS 10D. I am trying to decide what size of CF card to go for, but I haven't yet found any sensible information about how much space the images take up.

Lets assume a worst case scenario where I want to store max resolution images in Raw format. How many would I get on a 512M card?

[SoCal69]

Shooting raw, with largest JPG embedded, I get about 70 on my 512MB card. If I recall correctly, the file size ends up being about 7.5MB per image.

[evilenglishman]

sounds about right i get 140-155 on a 1gb

[Hoof Hearted]

I could live with that, 70 should be OK. Just so long as I don't get carried away with bracketing.

If you're thinking 512, I'd highly recommend two 256 cards instead. Then if something goes wrong with one... Or you can have 2 and a portable drive, etc.

I notice that the Canon CF cards are quite expensive. Presumably I can use any make of Card?

Shop for CF's here: http://www.mydigitaldiscount.com/

Get 512's or 1G's. That's the best bang for the buck. IMO 256's are too small and stifle the artistic process. About the time you get into shooting, then it's time to change cards. Also, cards do not go bad as often as some profess. I been shooting digital for about 4 years now and have not had a card go bad yet, but I have heard of cards going bad. Nothing lasts forever...

And yes, you can use any make of card; Read this recent thread: http://photography-on-the.net/forum/showthread.php?t=26231

Yeah,. get a 512,. but plan on getting a second one soon.. :)

Sandisk Ultra II cards are nice.... I got a 256MB for under $70US...

I see you're in the UK, so cool...me too. I have a 512MB CF card I got from Jessops (£130) in April, 03 and it gets about 76 w/ JPEG set at small/fine and the Hama 512MB CF card ($140) gets about 90ish also small/fine JPEG set. This will vary somewhat as it really is what the actual RAW file is. I have seen them 5MB, and over 8MB. It is all based on settings, and what you take the pic of. I have a FlashTrax drive I use to download images to and look at straight away which is cool. The advantage is that I can burn one, dump the card and continue shooting. I got 3GB downloaded one day and a lot of looking at the pics/zooming and stuff before it died. For the just in case factor there is a 2nd battery bought as well. Prices have come down in the going on year since they were bought.

Also remember that the higher the ISO the least amount of pics on the card.

[Hoof Hearted]

I think 512M sounds a good size to be buying. The supplier I use here in the UK sells a few different brands: Lexar, PNY, Kingston and Crucial. Are any of these to be particularly recommended or avoided?

Also, I notice the Lexar is available in 8x, 12x and 40x at prices of £86, £91 and £125. Will I notice the difference?

[iwatkins]

They are all much of a muchness to be honest. Stick to named brands like Lexar (I use the FujiFilm ones) and you will be OK.

The 10D cannot take advantage of the higher speed cards so don't expect spending the extra to get a fast card will help the speed of the camera.

Of course, these cards can last a while and you may move onto a newer camera in the next year or so that can take advantage of them. You pays your money...

As an aside, gliding eh ? That a Grob in the picture ? Anyway, I used to do gliding at Wattisham many years ago, loved it. So of course, when you get the 10D, lots of aerial shots ? And I'll expect to see shots taken with the 10D bodge taped to the end of the wing :D

Yes that is a Grob Astir in the background. It belongs to the club. My own glider - a Pilatus B4 can just be seen in the background.

I suspect the 10D will be too bulky to safely take up and use in a single seat glider, However, 5 of us are buying a Duo Discus Turbo this summer. I hope to make good use of the 10D then.

Now tell me what has the ISO to do with the amount of pics on a card?

I can't explain the why's or wherefore's, but did just get out the DRebel and changed ISO. 52 estimated shots at 100 ISO and 40 estimated shots at 1600. Interesting.

Hmmm... perhaps :
JPEG has better compression when an area is less noisy..., so more pictures... :?:

That's pretty much correct. "Noise" is detail. Detail takes up file space. Higher ISO's have more "noise" hence the file size can be larger. When you set the ISO on a blank car in your camera, the camera is estimating the number of photos it can shoot. Your mileage will vary depending on what you are shooting according to the detail and ISO of each photo.
