As above. Often the store bundles an SD card with the camera. So if anyone is at fault, it is the camera store (for not telling you to buy an SD card separately) or yourself (for not double checking, although I get it)
Originally posted by Docrwm Where possible Sandisk Class 10 is the preferred type.
This is the important part I would say. Sandisk or maybe Lexar. I would suggest against buying other brands, as they can be fickle. 8GB should be enough to begin with and very affordable. I wouldn't bother buying anything above 16GB, I prefer a couple smaller cards over one huge 32 or 64GB one. Just my thoughts
Oh, one more thing!! The camera stores photos on the SD card. Then you need a way to get those photos to your computer. You can do this by using the cable, or by taking the SD card out of the camera and connecting it to the computer with a card reader. Many modern laptops have a built-in SD card reader, but if your machine doesn't have a way to read SD cards, you might want to invest in a good SD card reader. I find it much faster than using cables to connect the camera. Just don't buy a cheap, flimsy card reader (especially online). Its worth it to pay just a little more and get a good, fast, reliable one.
