You should first make sure that the camera is set to
2816 x 2112 and that it is set to FINE Quality.
Page 24 of your manual.
I have not heard of anyone actually getting a mis-marked memory card.
For it to have the capacity you stated, it would have to be a SDHC (SD high capacity) card.
As far as "will this cause a problem somewhere", I would be tempted to call SeaLife and ask them.
Yesterday, I got a new digital camera (Sealife Ecoshot). I also bought a 1gb Sandisk SD card. I put it into the camera, and formatted the card with the camera. After that, it appears the card is actually 3.86gb. I had the picture settings set on the best quality it would take, and noticed the available pictures was much higher than it should have been (1232 instead of the 301 the manual says I should have) Upon hooking it up the the computer, and going to the properties of the removable drive (camera) in 'my computer' it listed the capacity as 3.86gb.
Has anyone seen this before?
Should I return the card (will this cause a problem somewhere?)
or Did I just get really lucky?
