 p.1 #15 · SanDisk Extreme Pro in 1D4? | |
For my applications it's related to shooting sports for a specific client that requires RAW files instead of JPEGs. The issue has been that through the evolution of the 1D series, the number of frames buffer capacity hasn't effectively increased much since the original 1D. The best so far has been the III with a maximum number of 30 images up to around ISO 400 or 500. The IV sits at 25, which is OK, but is slightly lower at high ISOs (as are all cameras).
Here's the issue with sports: One cannot predict the duration of certain action sequences. Say a running back has the ball and breaks an initial tackle that results in a cool shot, so you shoot that, then you shoot a nice running sequence, that turns out to be longer than usual, then he scores a TD, then there is the celebration with teammates, etc.. So do you take a chance and shoot the first half of the play, or do you hold back somewhat and wait to see what happens, thus missing some other images. For most plays this isn't an issue, but in every game there are at least a few extended plays that cause buffer issues and missed frames. @ 10 fps there's not much time until one hits the buffer on cameras previous to the IV, but with UDMA card support, it seems that one can stretch the buffer to a higher number than the officially rated number. It would be valuable for me to know just how much more performance a premium card like the Sandisk Extreme Pro will offer in this regard compared to less expensive 45 or 60 MB/s UDMA 5 cards.
I can't speak for Stan's needs... maybe he plans to shoot a 10fps 16MP motion picture?

For this upcoming job I need a 64GB card, and they don't come in any other variations. Second, I am intending to use the card in the 1Ds4 once it comes out, which has a notoriously shallow buffer and hitting that buffer is not common but does happen; there, every little bit of help counts.
