Eyefi Cards are available as:
- 4GB SDHC format memory cards
- 8GB SDHC format memory cards
- 16GB SDHC format memory cards
Note: Because SDHC works differently than standard SD cards, the new SDHC format is not backwards-compatible with legacy SD format cameras. SDHC cards 4GB and larger can only be read by SDHC cameras. Please refer to your camera's manual or your camera manufacturer's website to check if your camera supports SDHC memory cards.
