Darkslide:
I'm new here - please take this into account with regard to my question  ;)

I recently posted this on a well known 'rumors' forum, but foolishly forgot that a large part of the forum members can't spell 'photography' let alone own cameras (I had no response)...so I thought I'd try here

Context - off to visit Scotland in the fall - will be there a couple of weeks, and travelling light - Z6ll and a couple of lenses. I'm taking material to dump the cards / backup on the run, but I'm interested to know just how many images I can REALLY get on a 512Gb card.

I shoot RAW 14 bit lossless and according to personal experience, my files average 33Mb (I fully realise that RAW image size varies in terms of content, exposure etc.)

My math is probably severley wonky, but 512 x 1024 = 524288Mb

Divided by 33Mb = 15887 files

Is this reasonable? If so, I will be able to run a backup (protection) from time to time but continue shooting for a few days lol....

Many thanks in advance for your input

Ann:
Firstly: a warm Welcome to NG!

It will depend very much on how and what you shoot but on a wildlife shoot I might expect to shoot 600 images in a day but for Scottish landscapes I would expect perhaps half that number.

I suggest that you take two 512 cards and when one gets filled I would use the second.
Back-up the first card and wipe it when the second card is close to getting filled.

Enjoy Scotland!

Darkslide:
Hi there

Many thanks for the welcome, and the advice.

I have 'invented' a system to backup my images when travelling (involving a card reader, old telephone and an NVMe drive - works very well.)

However, being particularly anal about this whole sequence, I would very much like to A: backup and B: leave all the original files on the card/s. In this way I have more copies.

Somehow 600 images on a 512Gb card seems VERY low, and even with my weird maths, I'd get more !!

Anyway, perhaps one of the 'teccies' out there might be able to put me on track!!

Again, many thanks for your reply.

Best regards from France

PS If I were rich and/or American (who wouldn't have to pay high European taxes on things) I wouldn't hesitate to buy more 512/1Tb cards.... ;D

Bent Hjarbo:
In my Z8 it displays a number of 1.5k images on a 128GB card, so I guess you would get approximately 4 times that.
On my Z6 I get the same number on a 64GB card.
