Digetal carara card lack

Sorry, no. If it fit onto a Pentax camera then the lens has a Pentax mount. The Nikon (I assume you mean the D80 digital camera, or perhaps the N80 film camera) has a Nikon mount. Since the Nikon mount has a deeper flange distance than the Pentax mount, there are no adapters available to allow you to fit a Pentax-mount lens onto a Nikon camera.

Its possible that your have locked the SD card; remove the memory card from the camera and make sure that the physical switch is in the "UNLOCK" (up) position. See photo example...



Keep us updated.

Only cameras with a Pentax mount can use the lens.

SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

on your memory card is a little switch thing. if it doesnt work one way try putting the switch in the other position

Are you just plugging the camera straight into the computer? Does it come with software to install? Try plugging the camera in while the computer is off and then turn the computer on with the camera plugged in. Otherwise get a SD memory card reader that the SD card can plug directly  into and this connects straight to the computer.

Is your memory card locked? It won't let you delete pictures if it is. Check the little switch on the side of the memory card and move it in the opposite direction and then see what happens. Good Luck.

okay, so i had this same problem..
it can only be fixed by pentax so hopefully youre camara is under warrenty. its a software error and your camara is defective.

Hi again: About the black and white pictures on the TV... not normal I think... I have never seen your camera model but a common thing can happen to any camera!! Have you already tryed to connect the camera to your TV using a AC Adapter (D-AC8 in your case)? Are the connections Ok? You're connecting following the manual instructions? If you don't have it download it... :) http://www.pentaximaging.com/files/manual/OptioS5i_Web.pdf Regards
