Hi, I currently own a Pentax k10d but am looking to make the move to a Nikon. I had my eye on the D300 but the only thing I don't like about it is the fact it has a compact flash card set up. I currently use sd cards in my Pentax DSLR. I have never had any issues with these types of cards they are bullet proof. However, I have hired cameras using the compact flash and had many problems with compact flash cards being corrupted, and when I research online, it seems this is an issue still. I had read somewhere that only the Nikon entry level cameras have the sd card set up? Can anyone tell me what models the entry level cameras are and what the resrictions on them would be if any? Also can anyone owning a d300 confirm if they have had any problems with compact flash cards?
