Does anybody have answers for me?

Hey does anybody have a chart that shows how many shots one can get out of certain cards, when at 10.1 mp and shoointg raw or jpegs. i have seen them b4 but can't seem to find itnow online. i am looking at 8gb sandisk extreme III, so if you have a 40D and shoot in raw or jpeg seperate or together, how many shots do you get at full mp settings. i appreciate the responce.

thanks in advance,
Phillyguy

i am shooting a 40D gripped. FYI

Page 57 of your user manual has a chart for a 1GB card. Take those numbers and multiply by 8 to get close.

Actually, the best way is to pop in a card and look at the counter at the top of the camera. I use Transend 133X, 8MB CF cards in my 40D. The counter reads 420 for RAW plus Large JPEG. The chart mentioned above reads 59 X 8 = 472, a difference of 12% from the camera counter.

Pretty hard to do that when the OP doesn't currently have the card.

That 12% is well within the margin of error, since files sizes can be greatly affected by camera setting, such as ISO.

That is certainly your best bet...anything else is just a guess too. Like you said, ISO and other factors influence the file size, so any guess is going to do no better than give an approximate range.

Just keep in mind that the numbers aren't exact, they're an approximate. Specially if you do jpeg because of the compression. RAW is a little more precise in size from image to image, but that also changes.

You shouldnt need to know EXACTLY how many you are going to get anyway. If you calculate out say 470, you stick the card in and you get 450 on the number left counter, and your buddy told you he got 440, figure 400 and get another card if you feel youll need more in one session. Never depend on one card alone if the shots really matter and you should always have at lest one backup card anyway.

I shoot a 10.1MP XTi with the Extreme III 8GB card and get about 450 RAW+Ljpg on ISO 100. With the great rebates Sandisk has been running, why not get two 8GB cards and know you'll be covered?

Exactly.

with a 4GB card i get 560 on my 1D3 on jpeg fine

I shoot a 40D in RAW using an 8 gig card and get around 560 images on it. The RAW files are 14meg on average, the math should be easy.

The counter (or the tables, for that matter) is never going to be perfectly accurate. The actual image file sizes are going to vary because, even at exactly the same camera settings (ISO, shutter speed, aperture, quality, etc.) the amount of detail and contrast in the image causes differences in the file sizes.

I've had situations where the camera counter said I had 10 images left on the card and I was able to get a few more than that before the card filled up.
