While researching info about cameras, I came across several comments about the Nikon D80 using SD memory like it was a knock. Some reviews noted that the D80 uses cosumer memory and not professional compact flash. Any reason why the photo word views SD as a negative or sub-pro? I know for the most part DSLR cameras have always been Compact Flash but I have always prefered SD. The speeds are generally the same and SD is compatible with more products in the market. Upgrading from a Panasonic Lumix FZ-20, I already had SD memory and my old PDA had SD memory so I view it as a plus. Feel free to give your opinion.
