Default A70, what is the minimum speed CF card required?

What is the minimum speed CF card required to achieve the full capabilities of the A70. I guess this is mostly in regard to movie mode use?
Also suggestions to makes & stockists in the UK would be very welcome for the minimum speed card acceptable
Thanks

I dont think there is a minimum requirement for them.

The cards do not really work (speed wise) unless you get into dSLRs or other storage devices.

I could be wrong though.

i dont think i have high speed CF cards in mine and i can record a full 3min movie with it, i personally dont think that the brad makes much diffrence either, you will never be able to tell between non-brand and branded (same speed) when acually using them.

I have one byte sector (from amazon) and one PQI (2nd hand) both 128, i could get about 2 mnutes of movie, and thats what is quoted on the powershot site, you can get just over 4min with a 256mb CF card (from the powershot site too) all at 640x480.

This may be a stupid question but, I always thought it wrote to the camera first and then transfered it to the card. Dead wrong?

well......it does in a way. when you take a picture it imadeatly goes into the built in memory (or buffer) of the camera then it writes it to removeable storage. eg when you shot in burst mode you take pics, which go in to the cameras built in memory, when you stop shotting you have to wait while the camera emptys the built in memory by writing it to removable storage.

So, card speed really shouldn't matter, right?

well the faster the card the less time you have to wait for it to write.
