I have a Nikon 8700 which i use for work (i'm a realtor and so panoramic virtual tours with it), but would like to take up photography as a hobby. I want to upgrade my compact flash card and get one that allows me to hold down the shutter and take multiple pictures in a very short period of time. I don't want to go overboard and buy a top of the range card if the camera can't take advantage of it. What card should i go for? 100x? 133x? faster? Is there a brand to go for, or any to avoid? Thanks in advance.
