All my Sandisk 16gb Cards hold different amounts of images ?

[jasonsony735]

I have just wiped all my images from all my Scandisk cards all of them 16GB and everyone of them gives me a different reading on how many images they can store in RAW ?

One of them will only hold 307 images and another one 507 ? lol how is this possible when they are 16GB ? completely confused.

Well I'm sending them back to Amazon then as that's where i got them from ! The ones where you don't get any packaging ! I also looked on the back on the all ones that hold the most images after cleaned have Sandisk printed on them

don't get me wrong I have used these for the past year and never noticed until recently lol & have always worked great . I future ill make sure they have from amazon only and will check them once I get them right away.
