Should I keep separate SD Cards for my mirrorless camera?

Hello, I recently bought a used Lumix G80 for video use and I was wondering if I should keep separate SD cards for it. I have a Nikon D75000 I use for photography and I've got SD cards for it however I worry that using the same SD cards could cause issues related to formatting such as corruption.

The simple answer is 'yes'.

Regardless of issues with different formatting (possibly), the sheer inconvenience of dealing with remembering which camera has the card, or even worse, being out with both cameras and having to swap, means the answer is really self-evident.

Cards are (relatively) cheap enough to have one or more cards dedicated to each camera. Spoil yourself, buy another card

As long as you format the card every time you change camera there should be no problem. However, it is a chore and easy to forget. Much simpler to keep separate cards for each camera …

... and that applies whatever types if camera you are using. I have three Pentax DSLRs and each has its own set of cards.

Re: Should I keep separate SD Cards for my mirrorless camera?

you should, plus it shouldn't hurt to have extra SD cards. Always helpful

Not necessarily.  Just make sure your remember which card is formatted for each camera.  However, most cameras support the FAT/EXFAT file format so from my experience, at least with my Fuji and Nikons, is that it will just create whatever folders it needs if you put a card in the camera that was used in another camera.

Best practice is to try to keep the separated but only after you use them.  As for when they are blank, it doesn't matter.  Always format cards in the camera too for best results.

It's very important that cameras only use the SD cards that have been used with them in the past. Never swap cards.

Every different camera stores the data very differently which kinda etches the SD memory into a certain way of working over time. So if you pop the card from Canon to Nikon you may well have problems.

Re: Should I keep separate SD Cards for my mirrorless camera?

I’ve got 9 different cameras/bodies and each has its own card that stays with that body. Way easier than moving cards around.

I've never heard of any "etching", other than the fact that flash sectors have a limited (if large) number of formatting cycles.

If a card has been "etched" to such an extent that the failures (wearing out) are visible to "other cameras," that card isn't trustworthy to be used in the "first camera."  TIme to toss the card out and get a new one.

If you are just talking about the high-level files stored on a card, reformatting a card after you move it to a new camera takes care of that.

Statistically i think there is a higher chance of people formatting before they copy the files then coming here for help than having issues with using one card on separate cameras.

Besides, if a camera does require the card to be formatted it tells you so, if it doesn`t it doesn`t need to. If the camera accepts the card, the card is not malfunctioning yet the user has issues it simply means there is something wrong with the camera itself.

I do keep separate cards for each camera, but only so that i don`t mix them together and lose images etc.

I've accumulated so many SD cards over the years, I can't keep track of them. As long as I format in-camera, I have no problem.

for video, you probably want a bigger, faster card than for stills. Not much reason to swap. The smaller, slower cards, I use for spares. I don't care what I use them in.

IMHO, either method is OK, therefore, do what you feel is best for you.

I normally don't bother formatting memory cards, just used it fresh from the factory.
While I have at least 8 SD cards of capacities from 2 gig to 64 gig, I sometime use a card on D5100, D5300, D800 and even Kodak EasyShare and Lumix P&S - - - withOUT formatting between use. A 4 gig SD accommodates couple of shots from each camera. Please read the rest before jumping to conclusion.
.

The camera AUTOMATICALLY create a folder for each camera when a shot is taken with that camera. My Kodak and Lumix does not give me option to display folders other than it's own. SD I used on all the above camera automatically display the pictures in the folder with of that specific camera. I have observed that Nikon D5100 defaults to displaying the photos taken with that D5100 and do not automatically display the shots taken with D5300 and D800. The inverse is true with the two other Nikons. Fortunately,
I can MANUALLY select the appropriate folder(s) to view those shots taken with the other Nikons. I can also select the Kodak and Lumix folders BUT, the photos are hidden.
.
When I insert that SD card into your computer CD card reader, all the folders on that cards are displayed. I could select each folder to view and display the content. I could download the entire content of the SD card, either automatically or manually, The folder and file structure are preserved. I could override the default to suite my preference.
.
Memory cards are relatively inexpensive.
Play it safe. Use dedicated SD card to each camera,
On the bright side, you know you can use the same SD card in a pinch and retrieve the files.
There is "quick format" that only breaks the link between the index and actual file. Quick format allows overwrite of the "un-indexed" files.
There is "safe format" which wipes clean the SD card. I use this to recovered the space taken by "hidden files".

To be honest, I have cards now that are about 8-10 years old and have been installed and used in half a dozen cameras, and have never run into a problem.  The more important thing is that you don't simply swap cards between cameras without formatting them in the camera... that can lead to problems.  But as long as you format in camera, I have never seen anyone complain that they ran into issues because they used different cards with different cameras.

I would go with separate for each camera and even if they're the same make. I can't say I've tried using the same one across cameras however.

Easiest if you do keep them separate.

Only testing will tell. You certainly won't break anything, all that may happen is a warning that something isn't right with the card after doing a swap.

It's nicest and easiest to label cards and keep them apart.

Just now I tried a round robin swap of cards between some cameras and Olympus did not seem to care where a card came from, it simply adds its own folder to the card when it takes a shot, no matter what's there already.

Panasonic and Sony seem to be at odds with each other and cross-swapping between them leads to "card errors" or "image database errors" and again those cards into the Olympus have no problems - so far. But no guarantees on that as Panasonic and Sony both create a fussy set of weird folders.

I have 4 brands of cameras that may get used in the house between my wife and myself, plus others of vintage that may get used very rarely. In the past swapped between Casio and Olympus no problems.

In all cases I do keep cards and spares with the cameras and only rarely swap them around, unless I format them first in the camera to be used.

Cards are so cheap now that it is easy to have too many available.

Now with all this test swapping my cards are in a confused mess and need to get back to where they came from.....

Over worrying

As long as Nikon uses Fat32 (I trust so), it will be 100% OK.

G85, operates upon Fat32 file system. When a card is inserted, it will check for the required folder system ( indeed it could be very similar for most brand: DCIM/....). If nothing there, G85 will create a set by itself. On shooting, G85 will only write files onto its own folder system.

I trust most brands, including Nikon, will do the same.

As per an old thread about similar tropic, our dear friend, bcliff of Photonstophotos, should confirm that he shared SD cards among various brands, models etc on his testing without in-camera formatting every time.

I sometimes share a micro SD card, or OTG USB thumb drive between my Android phone and cameras including G85. Never face problem because of some specific files created by Android on the card...

You of course can do it for better disk management or whatsoever. But practically you do not need to do so.

FAT32 is standard for SDHC cards.  SDXC cards use exFAT.

It's not really necessary at all.  Just format the card in the camera as soon as you insert it (obviously you want to be sure the images have been copied).  I've shared SD cards between my Panasonic FZ-1000, Canon 80D, and Canon 7D II.

As long as it's formatted in the camera (this should be done every time anyway, even if being used in the same camera again), it's a non-issue.  And I have to say, this "etching" sounds made up.  Do you have a reference for that?? 
Anyway, first thing I do when I pop a card into the camera is format it, no matter where it was used last.
