Greetings and a short question

Hello to all fellow Pentax users! My name is Doug and I am from St. Louis, Missouri, USA.
I have a question concerning my Pentax K-x camera and the 128MB PNY SD card I have been using for awhile now. These items have worked great until this past week. I recently changed my ISO setting to 1600 and now the camera says the card is full even though I have emptied the card of all pictures. Did changing my ISO speed somehow corrupt the card? On a second note, if I increase my ISO speed do I decrease the cards capacity?

Have you done an in-camera format of the card?

Welcome to the forum, perhaps time to invest in more cards.

Welcome to the forums.

As was mentioned, formatting the card in the camera it is to be used in should prepare it for use in that camera. It will empty the card of any images that were previously taken. The use of 1600 for ISO should not cause much, if any, change in the file size. If you choose to shoot RAW type images instead of JPEG, then usually the RAW file will be larger in most cases, and if you shoot RAW+JPEG files at the same time the SD card will fill up faster than if you shoot one or the other.

1) No. 2) Not really. Higher ISO may in some cases produce a slightly larger file. But it would be insignificant. Certainly not what you are seeing.

Try doing a format of the card in camera and see if that helps. After you copy off all photos of course.

My workflow has been to format the card any time it goes into the camera. That is faster than deleting files and gives you a nice clean card. It also detects any errors the card might be developing. SD cards have a long life span but they do not last forever.

Thank you all for the input. I'll give the in-camera format a go.

Welcome to the forum.

Perhaps that card is dead. It must be pretty old by now. Get a new one, they are cheap.

At higher ISOs raw filesize goes up, but JPEGs should remain unaffected.
