Recommendations needed for Compact Flash cards for 5D Mk III

[zim]

Using 64GB sandisk extreme pro 90MB/s for my Mark iii
was using the same for 7d.

For the faster frame rate you need faster memory cards

As long as your not using the SD?

I use the sd for backup as jpeg for important occastions.

I've been using Transcend UDMA 32 GB 400x cards in my 7D for the past year.  The card keeps up with my burst rates.  I have gone through about 16,000 images on my main card without any problems.  They are currently selling for $45 on Amazon (down from $65).

I am currently in Geneve, filming the 2013 car expo and I passed by a local photo store to pick up a few extra cards. They have a very nice deal (relatively) on Lexar Pro 400x 32GB (~50 euro). For some reason, this card is not on the list of http://www.robgalbraith.com/bins/camera_wb_multi_page.asp?cid=6007-12452 as far as I can tell. Any reason to stay away from it? If it performs similar to the other Lexar/Sandisk 400x it it is fine for my current use, anyone got experience with that particular card?

I have been using Lexar 16gb 1000x for almost a year.  No problems whatsoever.  I also have the usb 3.0 card reader.  Very fast and it reads both CF and SD cards.

What's the fastes SD Card that can be used before the speed advantage of the card is limited to the slow SD slot in the 5D, is it simply any 133x card?

It really doesn't matter, the fastest ones write at 10MB/sec in a 5D MK III unless low level formatted.   A regular format does not erase old files, just marks them as ready to overwrite.
 
The higher speed specs are only for a new and fully erased card.  This means that you would need to do a low level format perodically (depending on the card use).  Otherwise, it will drop to 10mb/sec once it starts overwriting old files.  If you get a very large one, you can do a low level format less often, be aware that low level formatting takes a very long time, you do not want to do a low level format for a large card in camera, it may run your battery down.

Is there any way to low level format a cf card in a 5DIII?

Meh, turned out to be a "typo" (or so they said)... they were really SD and not CF
Guess the best deal is something like [size=78%]http://www.ebay.com/itm/SanDisk-Extreme-Pro-32GB-Compact-Flash-cf-Card-600X-90MB-s-UDMA6-32G-GENUINE-/281074150591?pt=Digital_Camera_Memory_Cards&hash=item4171532cbf[/size]
I have bought quite a few cards from china so far and they always seem to be genuine quality, but I guess you can never know

As said before, it's better to do it from your computer than from your camera. It's long enough to use a lot of battery. And maybe down your battery before finish to format.

You can do it looking in your menu and do "format".

But maybe you will prefer to use it to shoot than to format
