I bought a CF Card for my Canon EOS 1D, but I don't know why I cannot use it (the camera shows "Err" when I try to press the button).

Can Canon EOS 1D use 4GB CF Card?

My CF Card: A DATA Speedy CF 4GB (45x)

Thank you!

Can anyone help me please?

Thanks!

HI,

I'm 1D user too,
what I understand is I am using 1GB & 2GB CF
but the camara only can format as 1GB size,
my 2GB CF, I use other camara to format it and 1D still can store the photos in it.
4GB I knew before can not support
