Quote:If it's of any help I have a Nikon D300S which also has 2 card slots. I am not interested in using the secondary one for JPEGs so my choice was between back-up or overflow. I felt that the risk of card failure was less than the need for extra capacity so I chose overflow. My primary slot is CF with SD as the overflow location. It works for me.

Thanks for that input, Ewan. I feel that back-up would be of more interest for my circumstances rather than overflow, as I always have 2 x 16GB CF's with me at all times...good tip though, and one to keep in mind should I need that option.

Erm...I believe an apology to newdevonian is in order Malc

I can see every sense in his advise and because it was on a higher level than you were capable of understanding there was no need to be rude and ignorantTongue

SD cards are now capable of write speeds the same as CF so it would be a minor inconvenience to do a little research as to the right for your needs.....assuming you know what they are...which you clearly dont.Tongue

My top tip for you is read the manual....assuming you can read of course....if you cant then ive just wasted a few seconds typing thisTongueWink

Backup in case of a card failure obviouslySmile or you can set the camera up to write to the SD card after the CF card is full. But it all depends on what you shoot perhaps, you should read this dual cards I haven't got a 5Dmk3 yet but I use both SD and CF in a EOS 1Ds mk3. It appears Canon didn't use the latest spec for the SD slot and it also appears to slow the write speed to both cards to the slowest write speed (if your writing to both cards at the same time) to that of the SD card slot, irrespective of the read speed of the card. I hope I got all this round the 'write' wayWink The figure quoted is 133x, hope this helps.
