All SD cards are built to the same standard.
The standards organization is here:
Panasonic's parent company, Matsushita Electric Industrial Co., Ltd is the founder of the SD standards.
Panasonic brand would certainly be a good choice.
But I buy whatever brand is on-sale.
Never had a problem with any.
When you buy a new card, A L W A Y S format the card with the camera that it will be used with. If you fail to do this, you could end up with a card full of pictures that you can not access.
there are so many brands of memory cards on the market..my camera uses Secure Digital....anyone have any preferences to which brand is the best to buy (I need a bigger card)..
