Can I write Raw to my CF card and Jpeg to the SD slot?

I can't for the life of me work out how to do it.

I have a 32gb CF and an 8gb SD card and a 1Ds3 and a 1D4 and want to write Raw to the CF card but the Jpegs to the SD card, at the same time.

Is it even possible?

On the 1D3 it's done via the Func button on the back of the camera. I guess the 1Ds3 is the same.

They don't cover that in the manuals?

Yes, it is covered. They discuss the settings where you can say same files to both, just to one or the other as the primary, or files to both of differing types. I would set mine up so that raws went to the CF card, and JPG went to the Eye-Fi SD card.

p52 in the 1D3 manual that apparently people never read.

Heh! The one time I did that I just grabbed an old SD card I had laying around from "the old days" and didn't register that it would fill up with jpegs really fast! Well, it was just my only time shooting Raw+jpeg and I ended up not liking all those jpegs in my library and went back to Raw only, so no big deal!

Sorry guys, I don't have a manual for the DS3

You can download one from the Canon site -- just navigate to the 1Ds3 page for Brochures and Manuals -- here's the USA site (go to the bottom of the page for the camera manual), the UK may have a better link:

It's pretty simple w/ the MK IV. Set-up1(yellow) pick Rec. separately. Under shooting 2(red) select your image size for each card. FWIW page 57 of the MK IV manual.
Good luck

Thanks guys. I worked it out once I realised it was also to be done in the menu system.
I kept trying to do it with the func. button and the dials alone.

I'm just going to post again as that last one was my 666th post ooooooh

Heh! Glad you got 'er done, and now you have escaped from the "evils" of post 666!
