I have a Nikon 990, currently i am using a 128 MB compact flash card in it
and that works fine. 

Does anyone know the largest size card that will work in the 990?
Also: is there a speed increase with the newer cards?

I checked Nikon but they still dont even say the 128 will work but it
does and it works fine - i've filled it up twice with no problems.
Thanks
Eric
