Question about Pentax *ist D Digital Camera
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.

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.
