How to use cf and sd cards Mark5d3
« on: February 09, 2014, 08:38:39 AM »
Hi all,
I like to know how you use your cards. I've got the mark5d3 and there is the possibility to use both cards. Do you use both cards at the same time or only the cf card?

Depends on where I'm shooting and why.
Usually I just use the CF card and leave the SD as a "overflow card" in the case I'm shooting, I filled the CF, and can't stop shooting to insert a new card.
When I'm shooting in a situation where some people may want a jpeg copy of photos immediately, and I do not need fast shooting, I select to write jpegs to the SD and RAWs to the CF.
If I'm shooting something important I can't shoot again easily, I may write to both cards at once to avoid a single card failure will mean total data loss.
Settings are versatile enough you can choose what the best way for what you're doing.

I use the CF slot for RAW, and is my primary card.

I use the SD slot for JPG, and I keep a Eye-fi in it... the idea is that JPG is there for safety, and when I want to, I can enable the Eye-fi, for iPad previewing during a shoot.  I also have the back-screen review set for this card, and have my sharpness/saturation/etc. set on my picture style to match what I typically do in ACR, so I get a better idea of what my photos will look like later.

When I empty the CF card for the day, I format both cards in-camera before storing the camera.

i usually have both record raw

but i sometimes will set the SD to record JPG if i am not going to be doing processing and hand it off straight away

It's important to realize the potential write speed to SD in the 5D3 is nowhere near the potential write speed to CF.  The result is that when using the SD slot the buffer capacity fills up more quickly, and empties more slowly, than when only the CF card is being used.  To put this in concrete terms, if you shoot RAW to CF only you may get 10 continuous shots at 6 fps before the shooting speed slows down to 2 fps; whereas if you use the SD you may get more like 7 continuous shots at 6 fps before the shooting speed slows down to 1 fps.  The real-world difference can be significant.  This is why many 5D3 shooters, myself included, shoot RAW exclusively to CF, keeping a card in the SD slow only for overflow or backup purposes.

This is my approach too. I have the fastest Extreme Sandisk cards in both slots even though the SD is appreciably slower. I have tested the CF buffer and if I recall I can get 21-22 frames before the camera starts to choke but that is when only the CF slot is active. I rarely shoot and fill the buffer so I keep two 32GB cards in the card at all times set to mirror to both cards and that provides a level of data redundancy while operating in the field.

What I do is I keep a fast CF card in my body (only 8gb, 800x) and I shoot shoot shoot.  Then when there is a break in the action, I'll put in a 32gb sd card and copy everything over.  Remove the sd card, delete the shots on the CF card.  Rinse and repeat.

I'm sure others would be concerned about the deleting what is on the CF card just in case a file is corrupted... but that hasn't happened yet...

At the moment I'm just using a 32gb extreme CF as I prefer to have the full speed capability and I've yet to fill the card in a day's shooting in raw.

i use the SD as a jpg backup and the CD for RAW but I've never, ever, had a card fail nor have the few pros i know.  is this a real issue with cards made in the past few years? has anyone here actually experienced a card failure?

I shoot only RAW for stills, and I do a lot of video too.

I shoot mainly to the CF card, and use the SD card as overflow to keep shooting till I have a break to change the CF card.

HTH,

Wouldn't it just be easier to have a couple extra CF cards to swap out when they get full?

My wife washed and dried a card a few times and it died.  So there was that experience...

Yep... but I'm too cheap to pay for cards that lose value very quickly over time. 

Heck... even brand new, a $30 card will lose half of its value when selling on the secondary market...

I've yet to encounter the situation where I need to hand off JPEGs on an SD card, but the above is the approach I would take. (I've imagined the scenario where I'm vacationing and a tourist couple asks me to take their photo, but with my camera instead of theirs, and then gives me their SD card to record the JPEG on ... but I've yet to have that happen.)

Similar to what someone else has mentioned, if I fill my CF card (rare even at 16GB, because I usually shoot mRAW) and time permits (i.e., when I'm hiking and have some idle time between shooting sessions, I'll copy the images over to my (32GB) SD card in-camera, reformat the CF card and resume shooting. Otherwise, I'll simply pop out the CF and replace it with a backup card.
