MIC Gadget has an iPad adaptor that many professional (and semi-professional!) photographers might be interested in: a CF card reader that seems to work really well. They tested it on the iPad 2 and transferred three 21 megapixel photos in 4 seconds.
Interestingly, MIC Gadget says that since the iPad does not support 5D Mark II footages, they couldn’t watch the videos they shot on the iPad. A bummer. The adaptor is $US30. [MIC Gadget via Engadget]
