| My old Canon G3 supports CF I and CF II, and I've been using a 256 mb. CF II card without problems. Will larger capacity cards work with the old G3? I'm thinking 2-4 gb. At the time I bought the camera, I think the largest size was 512 mb. I read there are problems with cards larger than 2 gigs, but I don't know if that's really true. |

The Compact Flash format currently has cards up to 64GB available, but most CF devices can only handle up to 2GB versions, as they only understand FAT16 (File Allocation Table, 16 Bit), which, like early versions of DOS, only support volumes up to 2GB in size. If your camera supports FAT32, it may or may not work with larger CF cards (some work with larger cards, but only if they are already formatted for FAT32, and will format any blank CF card as FAT16, with a 2GB limit). Not many new CF devices being made, though, as the SD card family (including Mini and Micro SD cards, and SDHC cards) is quickly becoming the standard for flash memory cards. -Troy |
Thanks, that's in line with what I read late last night. I don't know if the G3 supports FAT32, so I went with a SanDisk 2GB ULTRA II, which is the maximum size FAT16 supports, as you said. I also understand the ULTRA II is about as fast as most cameras can actually support, so there would probably be no benefit to using faster cards such as the ULTRA III and ULTRA IV. At the highest resolution my camera supports, the card holds 974 images, which should be fine.

Most of your higher end cameras use CF... I use my Canon 20D with 4 gig cards, and it works just fine. Where do I get a 64 gig card? |
