Are you talking about a stand-alone camera or a unit that turns the Axim into a camera?
I have a Nikon CoolPix 880, and it uses CF-I cards. The Axim can show those files just fine.
It's still better to upload the stuff to the desktop PC, and then save to the Ax w/ Active Sync or Explore.
CF digicams are available, and the
Pretec camera
has been reported to fit the Axim, and work well.
