cf cards

[stuart wanuck]

for the purpose of bird flight photography can we address
the proper sandisc cards to use so that buffer life is extended
when shooting in high burst continuous modes

[Fabs Forns]

Sandisk Extreme IV should do it. They seems to both write and download faster.
Long time no see :(

[Michael Bertelsen]

I agree with Fabs, the Sandisk EXtreme IV is the ticket. I think there is new Sandisk Extreme Pro out now.
Its supposed to be twice the speed of the IV. Now that's fast!
I plan on picking up the 8 gig .

It depends on the camera. If it supports UDMA 6, then it will benefit from a very fast card such as the Sandisk Extreme Pro that reads up to 90MB/s. I use one of those in the Mark IV and the buffer clears amazingly fast.

What camera do you have? Rob Galbraith has an extensive list of different CF and SD card speeds sorted by camera.

[Grant Eldridge]

Axel is correct...depends on the write speed of the camera. For instance a D3 can write at 35MB/s. A Sandisk III only accepts data at 30MB/s while the IV does 45MB/s (I think those numbers are correct) so to get the best performance I'd by a IV. Best to find out how fast your body can't output the data and then get the apporpriate cards. The Sandisk IV are pretty reasonable now.

I remember reading that a 90MB/s card reads faster than a 60MB/s card even if the maximum write speed of the camera is lower than 60MB/s. I haven't tested it, though.

i usenikon d 300 will the faster speeds work?

According to this guy, the Extreme Pro works really well, the Extreme not so much: http://sportsphotoguy.com/extreme-disparity/

[Ed Cordes]

I believe SanDisk has re named their CF Card line. They are now Ultra at 30 mb/sec, Extreme at 60 mb/sec and Extreme Pro at 90 mb/sec. The old Ultra II, Extreme III and Exterme IV have been discontinued.

Here is some info on compact card speed versus how full the card is. It would be interesting to see how the newer cards do on the 1D mark IV and the latest Nikon bodies.

FYI, lots of rebates going on right now at Adorama on Extreme III and IV. good time to stock up. http://www.adorama.com/IDSCF8GE4.html?emailprice=t

Yes, for the Sandisk Extreme Pro, too.

I will be shooting a Mark IV w/ 16 gig Sandisk Extreme IV Pro cards in YNP the next two weeks, leaving tomorrow. Will report back when possible on both. I can tell you it is difficult to overshoot the buffer with the new card.

Best,

Very interesting, if that would apply to the 1D4 then the Lexar might be even better than the Sandisk Extreme Pro.

[Jeff Donald]

I'm sure the 1D4 isn't any slower than the 7D. It's funny, because for a long time SanDisk was thought of as faster in Canons and Lexar was faster in Nikons.
