How many pictures will a 1GB SD card hold using 7.1 megapixel Canon A550 camera?
Hi boardgirl, congrats on the new camera! I’ve recommended earlier versions of that camera to several of my friends and they’ve all loved them. According to this crucial.com memory card guide, a 1GB memory card will hold 264 photos. They based this figure on a filesize of 3.7MB per photo. But I won’t be surprised if you fit 300 or more photos. Why do I say that? Because Crucial also says an 8 megapixel image filesize is 4.2MB, and a 1GB card should hold 232 images. I’ve got an 8 megapixel 30D, and right now I’ve got a card in my reader that’s holding 254 JPEG images, and they’re only taking up 546MB. That’s an average filesize of 2.4MB. Granted, some of my photos are black and white, but that’s still a considerable difference. I suspect that Crucial errs on the conservative side by using a larger than average size for their calculations. People would complain if they advertised the card
