I reviewed Apple's Camera Connection Kit when it first came out. The Apple kit is two adapters. One is an SD reader and the other is a USB port designed to connect your camera directly to your iPad for image import. The one glaring omission is the lack of a way to bring in images directly from a Compact Flash (CF) card. During my review, I showed how you could attach a standard (San Disk) reader to the Camera Connection Kit and bring images in directly from your CF Cards. However, shortly after I did the review Apple released an iPad software update that basically reduced the amount of power that the dock connector outputs making it virtually impossible to power a card reader. I guess they didn't like people plugging in all the things (keyboard, drives, etc.) they were plugging in to the Camera Connection Kit on their magical devices. That left us with the only option being to use a USB cable and connect the camera directly to the iPad. While this works, it's slow and will drain the cameras battery during long transfers.
Problem Solved by M.I.C
This Hong Kong based company has developed a CF Reader that attaches directly to your iPad and allows you to import your CF cards (up to 400x speed cards) right into your iPad. Of course I ordered a couple of these immediately and mine just arrived this past Friday. I was hopeful and doubtful at the same time. I just couldn't figure out how they would get around the power problem. Well, they did! I plugged in my standard SanDisk 8GB Extreme IV card and it showed up just like the Apple Camera Connection Kit does. I imported my RAW (.NEF) files with no problems.
You can order the M.I.C CF Reader here. They are back logged (as you might expect), so give it a couple of weeks.
I would normally do a video of such a gadget in action. However, they already had a video that shows it in action and I concur with the results shown. So here it is:
