While I am hear learning about coins, I am happy to help with something that I know a little bit about!
- Any SD Memory card will be fine. If you are only going to shoot coins, go for capacity, over speed. If you want to shoot bugs with that Macro, might need to find a better memory card. The standard cards at Best Buy write at 4mb per second, which is horrible compared to the XSI that you are shooting with, which I think is frames per second. So, the standard Class 4 Memory card will take 12 seconds to write what your camera can take in one (assuming large Jpeg setting, not using RAW)
- one more thing, and don't ask me how I know this. Never....EVER...delete an image on your card. Only delete it once the images are downloaded on the computer. SD cards have a fixed memory structure, as opposed to PC hard discs which have the ability to split a file. If you take a few shots, then go through a delete some, you will run into a problem. If you delete a 4mb image, then take a 5mb picture, it will try to stick that 5mb into the 4mb slot. Wont work, and your memory card will get locked.
- Once you copy your images to your PC, and your HD backup, then reformat the card...every time.
If you have any questions, feel free to PM me.
