memory card question

I have an SLR and a compact camera

I have a 16Gb Class 10 SDHC sandisk memory card

if I put it into my Nikon D7000 it says 445 pictures I can take

if I then put it into my Sony RX100 compact camera which is 20 mega pixels, I can take 775 pictures

why can I take MORE photos with camera that's got a higher pixel count ?

both camera on their highest RAW setting

What ISO settings? The higher the ISO the larger the files get and the fewer you can store. The reason is that higher ISO settings produce more noise which reduces the effectiveness of the compression algorithms.

ooo I did not know that
thanks

I'll double check the setting

checked both camera, both were set to auto, so I tried lowest ISO and the highest, no change to how many I can take

From what I can get from a quick google it looks like the Sony uses a compressed RAW format which will let you get more on the card.

thanks for the info
