|Home >> Ask Olympus: Advantages of digital camera specific lenses|
What are the advantages of lenses that are designed specifically for digital camera use?
Answer: Although the small size of the individual pixels in CCD and CMOS image sensors enables them to capture even more detail than film, the sensitivity of the sensor elements is highly directional. That is, they respond best to light that strikes the elements straight on. With lenses designed for use with film, the light rays passing through the periphery of the lens strike the image sensor at an angle, and this tends to degrade picture quality at the periphery of the image area. On the other hand, lenses developed specifically for digital camera use can be designed to match the imaging characteristics of CCD and CMOS sensors, ensuring high image quality at both the center and the periphery of the frame.
On my xD card, I sometimes get double exposures, or it cannot read the photo. What could cause that to happen?
Answer: Your memory card has been corrupted. You may be able to restore its functionality if you reformat the card inside the camera; however, be advised that there is no guarantee that you will be able to retrieve the images that are stored on the corrupted card.
Olympus does not offer a service to recover data from corrupted memory cards; however, a number of companies do offer this service. In addition, commercial software now exists that may help you retrieve files from a corrupted card. Olympus does not endorse any specific brand or product, but you can find many options by searching the Internet for “digital image recovery.”
If you are able to save any of the images, transfer them to a computer and store them on a drive different from the one that represents your camera when the camera is connected to the computer. Once you have saved all the files you can, format the card.
How long does the picture image stay on the card?
Answer: Images and movies recorded on Olympus xD-Picture Cards are persistent. They will remain for the life of the card, until you remove them.
Transferring files to a computer does not delete the original files in the camera. To safely delete your files, use the camera’s Erase or Format function. Be sure to save the files elsewhere before using these tools. Once deleted, the files cannot be retrieved.
