I currently have just a standard sandisk 8gb sdhc card.

During some continues shooting I found it only shoots two then a lil paus then two then will slow right down and says busy between shoots.

Is this my camera processor or is it the sd card as I know you can get sdhc 3 etc

any help welcome
 
My Nikon holds them on the camera when the memory card can't keep up. If the Canon doesn't do that it might be worth getting a class 10 SDHC if your going to do a lot of continuos shooting.
 
I think there is a big difference in the class 10 performance! Are you going to do a lot of continous shooting because the cards are pretty pricey.
 
Hmm I wouldn't say ALOT, but I wouldn't like to get my 6 continuous raw shots without the pauses I get now which is about half a second upwards after the first two shots. Even four would suit me.

There any other choices?
 
I'm not sure otherwise maybe another Canon owner might be able to shed some more light on the situation.
 
I used to get my 450D stalling a lot when I was using bog-standard SD cards but when I upgraded them to Sandisk Extreme 3 SDHC cards it rarely happened. Extreme 3s are 30 megabits a second. Sandisk now do five different speeds in their SDHC range with the fastest being 90mbs. These are eye-wateringly expensive, unfortunately, but are probably too fast for a humble 450D anyway.

If you have only SDHC cards rather than ultra 2s or extreme 3s these will not be able to keep up with a 450D, even at its relatively modest frame rate of 3 and a half shots a second. If you're shooting in raw, it will be even worse.

I would consider upgrading to extreme 3s at the very least. You can generally get these from Amazon or Play.com for reasonable prices.

thanks, I will see if I can pop to a shop and test it out see how it goes :-)
 
Hi a friend has the 450 D and uses the new Ultra cards or the Extreme 3's and on continous shooting he can shoot in XS of 16 shots with no buffering on the camera :thumbs:
 
I've got both of the above memory cards and they are fine on the 450D, continuous shooting.
 
I haven't tested on raw and jpeg together, but I've tested on raw and it was fine. I would get the Extreme III if you were planning on that anyway.
