I found this reply in a similar thread in another forum

"The manufacture should indicate if the camera will be SDHC capable. SDCH will allow 4G and higher for capacity. The speed does not matter for single shots, a class 2 is sufficent. Higher speeds would be applicable to digital movie cameras only as the bottleneck for single shot is the camera not the card. I have a Nikon DSLR and wasted money on higher speed SDHC. The additional capacity was great for taking a lot of pictures but the speed beyond class 2 was a waste of money for the application".
Maybe this answers my question......unless someone knows otherwise
