Compact Flash Memory Cards

[Blazing fire]

I suspect that the cards probably can write at the speeds specified, but (a bit like printer speed tests where I'm sure they print a single full-stop in draft mode for the test) probably under certain conditions that just happen to be "ideal"

I agree! And ideal conditions are far and few between.

Not often - depends what I'm shooting. If I'm trying to capture some nice waves on the beach - and I've filled by CF Card (and am on to the SDHC card) then yeah - not hard. The one of the few downsides of the 1Ds3 compared to the 1D3 is that the buffer is only good for 12 shots -v- 30 (assuming RAW). This weekend we have some high-powered boats racing (F1) - and it's easy to max it out in those circumstances unless I shoot JPEG.

If you reduce the resolution of the 1ds3 to that of 1d3, will you get a buffer of 30 RAW shots?

It can only go to 2784 x 1856 (5MP equivalent), and then the buffer goes from 12 to 18, which is quite surprising considering that the images is only 1/4 the original size.

On JPEG (10) it goes to 42 and on JPEG (8) it goes to 56, so it's not really much of an issue - as much as I love RAW, JPEG is just fine for sports type work.

Also a happy Sandisk userwith a selection of Ultra 11's & extreme 111's.
Have always purchased from 7day shop and never had any problems (and they are genuine!)
They have them on special offer at the moment, worth a look.
