Free CF to SD Card Adapter?

[Stitch-Up]

My Canon 5D Mk3 has two memory card slots 1. A CF Card Slot & 2. An SD Card Slot.

CF cards seem to be less available these days and also more expensive per Gb memory.

I only just noticed there are adapters CF to SD this would mean I could load 2 x SD cards in my 5D.

Will this work with the 5D? Any reasons why not? Any good reasons to use one of these adapters?

Will be interested in any comments.
Thanks
John

It'll work, but they are just a bit crap.

Plenty of CF cards available on the used market.

I bought my cf card from this ebay seller, it arrived, works and as far as I can tell is a real SanDisk

CF cards have faster write speeds, and are more harder wearing, I don't know if this matters to you.

The card records photos almost instantly, ensuring you will catch your best shot. Capacities up to 128GB accommodate high-quality file formats. Read speeds of up to 120MB/s (16GB - 128GB capacities only) make transferring images to your computer fast and simple.

Plenty of brand new CF cards available too, and given the size of the files on the 5D3, 32 or 64 GB will be plenty (unless you are taking many thousand shots a day).

Bear in mind the SD slot in the 5D3 is considerably slower than the CF slot

Why You Should NOT Use an SD Card in the Canon 5D mkIII

It turns out that the Canon 5D mkIII reverts the SD card write-speed to 20MB/s no matter what card is used. What's worse, if you are using a CF card at the same time, the CF card will also be crippled to the 20MB/sec. Read more to find out.

This.

It’s not like they cost what they did when 4gb was a big card. They’re still relatively inexpensive in the grand scheme of things.

Thanks all

Do CF cards have any benefits over SD cards?

Thanks for that, as I don't have any 'serious' reason to stop using the CF card, you've provided a good reason why I should stick with them I'm sure I've read similar sometime in my distant past
