Image review from two cards

[brentb]

Hello. Newish to SL, and I have a question about image review during playback. I have the camera set to backup from one card to the other. While deleting images from the card (1), in camera, I noticed I was seeing images that I had already deleted, then realized I was now scrolling through card 2. If this is supposed to be a backup, then when I delete something from card 1, shouldn't this be synchronized to card 2 as well. It seems counter intuitive to have to pay close attention to the little number that indicates you are now on the second card, or have to repeat the entire process of selecting the same photos to delete. My understanding is that is supposed to be a redundant backup in case there is a failure of card 1. If I needed space, and deleted a bunch of photos from card 1, I would then have to find and delete the same photos on card 2, not only is this is a waste of time, it doesn't really accomplish the task of having an exact duplicate of the first card. If I choose to delete an image, shouldn't it be deleted on both cards simultaneously?  Am I missing something here?

It’s a very basic failsafe feature really just intended  to protect you from loosing files if your primary card fails. I don’t know of any camera that does the functions you want. I use 128gb high capacity cards to avoid running out of space.

I think the answer is that Leica assumes that if you are concerned enough to make two copies of every image, you will also never delete on the street, but will carry extra cards.

As an aside, what’s the reason or rush to delete anything in camera?  Storage is abundant and cheap, takes time and attention away from shooting, and PP provides greater flexibility and efficiency, while also potentially adding to learning by giving perspective to miscues.  Plus I wouldn’t want to accidentally delete an image in camera.  Never used the functionality on any camera.  YMMV.

Exactly... my pics get deleted from the card through the computer... never saw the need to do on any camera I’ve had.

Only delete files if you run out of space and there is no other way to continue shooting. Do housekeeping of files only at home, not on the street.

512 GB now costs less than 100$. Buy a few cards for reserve. (And forget about deleting single files). Set priorities (double copies or more space). UHS II is only for video. Photography can live with UHS I cards easily. (The buffer speeds the camera up, not the SDXC card.)

Partly disagree - UHS II gives you much shorter time needed to transfer the files to your computer (as long as you are not using older hardware). And after a day´s shooting with SL2 and its on average 80mb files I notice a significant difference from using 250mb/s UHS II cards vs the UHS I cards I had in my previous SL (601).

Ok fair enough points about large cards, and deleting at home.  You might not have that option if you’re on vacation somewhere without computer access and no more cards and shoot more than expected, but If you do have that option then what’s your process for that? Are you copying everything to the computer at once, then deleting everything from both cards at once? If not, what’s the best method to selectively delete the SAME images from both cards? Sometimes you just want to delete some of the files and keep filling the card. How do you make sure you get both copies on each card to keep them in sync?  

[caissa]

Go for lunch or tea, while the files are downloaded. No need to wait for it.    If you are a pro who is in a hurry, then you can easily afford the fastest cards and enough of them (the cheapest part of your equipment). Then this whole discussion is unnecessary.

[Exodies]

Copy everything to the computer then format both cards in camera.

if you have so little confidence in hardware that you mirror your SD card in camera then it would be sensible to carry two card reading disc drives with you to offload the cards every few hours. I can’t blame you for being paranoid but I really do think you could be consistent and thorough about it.

Its not a matter of time. Its the matter of deleting both versions of each photo from each card.

Its not that I lack confidence in the hardware. This is my first camera with Dual SD slots. I'm merely taking advantage of what Leica has provided. Just looking for the easiest way to erase the duplicate versions on the second card to match the first. If I have to remove the card and copy everything, then format both cards each time, seems a little counter productive, when I just want to remove a few files and keep shooting on the card. If Leica (or any manufacturer) expected you to remove the cards and do everything on a computer, then the delete functionality wouldn't be built in to the camera at all. 

[verwackelt]

You should not mix what is called backup on a mac or PC with that what the camera manufacturer calling a backup meaning the second card slot.
It is never meant as a syncronising function like an iCloud backup or similar.
You have to live with that it is just a duplicate copy of your photos without that syncronising thing.
I  copy only my first card to my computer from time to time. If then an error should occur i have the second card as a backup (not syncronised).
I always format then both cards in camera and start again.
When on a trip without computer, i store always both cards and replace them with two next cards when i get short in space.
You should always have enough cards and batteries with you. 
As in filmtimes you always had enough films in your bag…

Leica also put ‘snapshot’ mode on some modern M’s. And JPEG mode. Doesn’t mean I have to care about either.

Anybody who can’t figure out how to carry a couple of extra, large capacity cards has likely never shot film, at least not large format.  

One needs to develop a rigorous backup routine for computer files, regardless of SD cards.  I routinely format my cards in camera once I backup results.  Simple.

Hmm. Well the 60+ film cameras and Speed Graphic I have would indicate otherwise, but Ok. Are you not using the recommended SDFormatter app then?

 

[verwackelt]

I spoke to different technicans from Panasonic and Nikon service. All technicans suggest to format cards in camera because then they interact with the camera best.
I never had any problems with my cards only formatting in camera never on my mac…

Well then, why the worrying about not having enough cards? Have you lost your discipline... or your pockets?  

No, I only format in camera.  Never a problem.  And equally recommended, depending on source.

I also don’t shoot much more digitally than I shot in film days.   Never have come close to overfilling cards.  But that’s just my approach.

I never said I was worried about not having cards. I asked a question about workflow, specifically the best method to make sure I deleted the same photos from both cards. If your method is to shoot then reformat every time, then so be it. I don't always have the capability or desire to offload to a computer instantly, hence the question.

With older cameras I formatted first on Mac then in camera only. I have trouble believing that one formatter can be better than another. Timings won’t convince me; I need source code proof. With current cameras I skip the Mac format.

 

As you are writing each shot to two cards just because Leica provide the option then it really doesn’t matter what else you do.
 

Eccentricities must be consistent otherwise they don’t deserve respect.
