So I've been lusting over one of these new Eye-Fi SD cards, and was bummed to find out that they are currently not available in Compact Flash format. Then I found some cheap (~$20) adapters, in which an SD card slides inside a Compact Flash blank, and could then presumably slide into my EOS 40D.


Does anyone have any experience with this? Does it even work with EOS DSLRs? I don't mind throwing away $20 to test the theory, but I don't want to drop ~$200 on the Eye-Fi card and then find out it isn't compatible.


Any real world experience, or knowledge of this scenario would be greatly appreciated. Also, if you know anything about the future of Compact Flash Eye-Fi cards, or future SD capable XXD EOS DSLRs (I've heard the 60D might offer this), I'd be interested in hearing about that, too.


Thanks!
