I have a Canon 20D and was looking to buy a memory card. Turns out there are lots of options that vary in price. This got me wondering, what should I be looking out for when buying a memory card.
Based on some research that I've done, I have some points:
What is the maximum memory size your camera supports ?
- From what I can tell, the 20D supports up to 8GB (could not find it in the manual), so anything over that would be a waste. Although I did find some posts where users claim they can use a larger card, as long as they dont format it using the camera. Can anyone speak to that? Personally I might just stick with the limit set by the camera.
- I am still trying to figure this one out. I saw this post on speeds that sheds some light. Essentially the write speed of the card should be higher than that of the camera, which makes sense. However how do I figure out the write speed of my camera? Does anyone know what the write speed of a Canon 20d is?
What brand to buy?
- I currently have a SanDisk Extreme 512MB card. That is why I started looking for the same card with a higher capacity. A Kingston or Transcend is approx. $15 while a SanDisk is over $30...
- Not sure how important this is, but I do live where the temperature can go pretty low below 0F. That doesn't mean I will necessarily be doing photography outside in that temperature. What kind of problems do people run in to with low temp?
Are there any other things that I should be looking at?
