I haven't been able to get it to work.
Does anyone know why Eye-Fi does not make a CF card?
It's a very good question. Maybe it has to do with the relative demand of SD cards versus CF cards, or perhaps the relative manufacturing costs for adapting the tech to CF? It's really frustrating, I tell you, and so I'm tethered like a helpless goat
. Just thought I'd also add: stay right AWAY from SD-to-CF adapters as they are notorious for being very unreliable.
