SD for D90
Hi, I have a D90 and shoot a lot of windsurfing and kitesurfing photo's. I use Sandisk Extreme Class 10. I have a few other cards and its the Class 10 that makes the difference, they keep up with the buffer and D90 firmware. The Gigabites are not so important, I normally use 8Gb as it suits my work flow, 16Gb, 32Gb will all work if its class 10, thats the benchmark.
