Can someone explain this memory card discrepancy

I've been an owner of the K-1 for 2 years and I've been using dual 64gb cards in it with no problems. When formatted they show a capacity of 1618 shots. Not a problem and in line with my expectations.

I decided to rent a K-1 Mk ii for a trip and decided to get 128gb cards for it and to use those in my original K-1 when the rental was up.

Now comes the strange part. In both the K-1 mk ii and my original K-1 the capacity being reports for the 128gb cars is 1569 shots. Why are cards with double the space showing up with less capacity in both cameras? I'm guessing the K-1 has no issues with large cards, but this baffles me.

Can anyone explain this to me?

The number of photos remaining is an estimate, this is because both jpeg and raw use compression (the latter is lossless), so file sizes depend on what's in the image. I'm guessing the mark ii uses a different method to calculate expected file sizes.

I would verify that the 128gb cards are indeed 128gb. Counterfeits are out there. Or they might not be formatted correctly. Try formatting them in the camera.
I suppose it is possible that the K-1 does not recognize 128gb cards properly, I don't have any that size so I cannot confirm that they actually work. Someone will chime in I'm sure.
What brand of card?

I'm using raw and a 128GB Card and a 256 GB card both sandisk
The camera reports

3220 Pictures for the 256 GB Card and
1612 Pictures for the 128GB Card

Both card work fine, the small one for 3 years, the big on for nearly one year.

The sizes are consistent with the values read in my pc and the calculation with the file sizes. (typically 46 MB per raw picture, this is the average value from 32000 picures)


In jpg I get 11124 pictures for the big and 5572 for the small card in the highest quality, but I don't use this format.

Your shown value for the 64 GB card are wrong, it must be 808 for raw and 2799 for jpg, I've tested it with a card from my k3.
With a 32 GB card you get 402 for Raw and 1394 for jpg, I've tested it with a spare card from my k3

The real values for the picture count are round about 60% higher as shown on the camera display.

Are you sure that you get real cards and no fakes? There are a lot of fakes around. It seems as if you got such.

If you are shooting raw your camera will show about 1600 shots available on a 128GB card. if you ever got close to shooting that number you will find in practice that you will get more, a lot more.

The discrepancy you are seeing is as joergens.mi has stated. Raw versus jpeg.

Okay, Mea Culpa. I screwed up. While I thought I had 64GB cards in one and 128GB cards in the other, I actually had two sets of 128GB cards. So the minor difference between the two is minor 1618 vs 1569. That can be easily explained by the formatted capacity of the two brands Samsung (1618) Patriot (1569).

Thanks and again I apologize.
