I have been using the *ist Digital since October of 03 and absolutely love this little camera. Quality is excellent. Since about a month ago I noticed when I put a 256Gb card in camera, the camera says I should get 57 photos in High Quality Jpg. Yesterday I shot a 256 card and when downloaded to my computer I had 103 images. Anyone had a problem with getting many more images than normal. I have checked and always shoot at Hi-Res Jpg. This happens on all the different cards I use including 1GB ultra SanDisc. I am getting double the amount of images on all cards. I contacted Pentax, they have no idea why this is happening.
When images are opened in Photoshop. The size of image is same as always with no loss of quality in any form. Anybody else experienced this problem. I am still sold on the camera and intend to purchase a second body with the new 16-45 lens.
Need your help on this dilemma.

Re: Minor problem with doubling of image quantity
It happens because there's a range in size for compressed images depending on scene content - could be 2MB (lots of plain surfaces, sky etc which compress very well) to 4-5MB (lots of grass, leaves or high ISO noise). The camera uses the worst case number to tell you how many images it is sure you can get on the card: as you shoot you may notice that it writes an image and doesn't decrement the number of images that can be recorded. It is doing the right thing - the alternative is for it to give you an optimistic number rather than a pessimistic one, and then you'd all be complaining that it said you could fit 100 and you only got 60.

On my D-90, the camera is set by default to store two images of each picture I shoot...raw(NEF) and JPEG Fine.
The raw image contains far more data than the JPEG image and is therefore the best to use when you want to do extensive detailed editing.
The JPEG image is used when you only want to do minor editing before publishing or sharing the picture.
JPEG images deteriorate quickly when subjected to editing while RAW or NEF images can handle many more editing steps before losing quality.
If you're shooting snapshots, you probably don't really care about extensive editing and you can save a lot of space on your memory card by changing your menu settings to store only one image of each shot.
To do that, go to the wrench icon in the menu then scroll to image quality. Click on "image Quality" and you will find multiple lines to set the camera to your preference. Choose the one you want.
Yes. The CCD chip has died and they don't tend to be cheap, but I would call around to other service centers before giving up hope. $400 seems a little steep to me, but I don't often work with Pentax units, and haven't priced their CCDs recently.
Your lens would need to be absolutely filthy with enormous dirt specks to cause the fault you describe. Dust, fingerprints, and regular minor debris simply doesn't show in the final image. In any case, you cannot clean inside the lens without dismantling it and that is a job for experienced specialists only.
Your fault is a dirty image sensor. You can buy sensor cleaning kits, but if you're inexperienced with them or trying to clean the sensor in a dusty environment you'll just make matters worse. Many camera shops offer sensor cleaning while you wait at relatively low cost. The reason you don't see the dirt when taking the picture is either because you're looking through the optical viewfinder or because the LCD screen simply doesn't magnify the image enough to show the marks which are present in the image.
You can prevent the dirt from reoccurring by never leaving the camera with the lens throat open for more than strictly necessary, and by always trying to keep the open lens throat pointing slightly down when swapping lenses.

Press the menu button and go into the image mode setting. Use the right arrow to go into the table of quality options. Use the up/down on the dial to select the file size (quality) you want. You will then see the quantity of images the card has room for, at the selected resolution.
I've had this problem... it was, of course, the quality setting which was reduced to lowest by whoever was doing the repair. I have never used this setting almost always using the *** setting or RAW. When I set these I get the kind of numbers I was used to in my remaining images counter. I am so glad I came on this forum and now the only fly in my ointment is the embarassment I feel for not having spotted the problem and the realisation that this may have been the problem before and I need not have sent my camera off on the second occasion.
