Compact Flash Memory Cards


I shoot digital with the Canon 300 and the Canon Eos 1ds. I have several memory cards, all 512mb and up. Two of my cards are the SanDisk Ultra II, and the others are regular compact flash cards. I recently took pictures outdoors with plenty of daylight, and some of my images were blurry. Could it be the difference in my flash cards? I did not use a tripod, but these were portrait shots of children, and I took 188 images and only 100 were not blurred. Is there really that big of a difference between memory cards? Thank you!

  I can't see how your problem would have anything to do with the memory cards. The files are either readable or if corrupted, they aren't. There's no way a bad card would result in a blurred image. 99.999-percent probability it is your technique (camera shake from hand holding, poor focus, unclean or scratched lens/filter, etc.) that is causing blurred images. Can you post a sample?

  Were the blurry ones on the card in the heavier camera? Or use the info and compare speeds/ISO between cameras.

  1) No, the card does not affect image quality. A low-quality card can fail on you and result in lost pics or much slower transfer. The SanDisk UltraII cards are very highly rated cards and will give you reliable performance as well as high speed ... whatever your camera can dish out.
2) You said you were shooting in daylight. Did some of the subjects perhaps wander into the shadows or perhaps the camera's ISO/shutter speeds were set too low/slow?
3) Another possibility is that there might have been too much light, resulting in areas being blown out. If these were one of the areas the camera was trying to AF onto, it would fail since there isn't something for the sensor to lock onto to determine "focus".
I use a mixture of Kingston CF chips and Lexar Pro CF chips, also 512MB. The only time when my camera blurs on me is when I'm hand-holding a macro shot in dim light or when I've been less than gentle with my camera. ^_^;

  Your cards shouldnt have anything to do with that. Im gonna guess improper camera settings. Did you bump something by accident? These things happen easily, taking cameras out of bags and so forth. Another thing, how long a focal length lens did you have or had your zoom at? Longer lengths and a side breeze will do it too. Another thing is using a small apature, that will make for a slower shutter speed. there is lots of things it could be.
