The extra speed is not important for slower working styles. For faster working styles (action, etc) it can be important, especially if you have a small buffer. I have several times switched from my D100 to the lower res D1h for model shoots because I was working fast enough that the D100 was having to stop to write (buffer full) and I was missing shots. > Card write speed is more of a marketing tool than anything, real world > operation is where it counts and there isn't much in camera speed difference > between most cards, see: > > http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6432 Do check out rob's tests. For "most cards" it probably does not matter much. I wouldn't expect much difference between most manufacturer's high speed offerings. I have a bunch of older Sandisk 128 and 256 MB compact flash cards, baseline models with no high speed qualifications, that I bought myself. The company bought me 2 Microtech Xtreme 256 MB cards and a Lexar 12X 256 card. The speed difference is QUITE noticeable in some conditions. When I'm shooting action at 5fps with the old cards I will sometimes see the camera writing data for some time after the action has stopped. With the new cards, by the time I take the camera down from my eye it is done writing. Of course the buffer on the D1h makes this a non-issue, but the speed difference is noticeable. DJE
