Change to V1.02:
  • Correspond to the SD memory card greater than 1GB, also Version 1.02 include the additional function which was released at Version 1.01.

Change to V1.01:
  • At the long time exposure situation such as astronomical photography, green noise might be generated partially on the image when the noise reduction is turned on.
    This phenomenon only occurs rarely under special shooting condition such as starry sky, and will never occur at the general situation that we are assuming.
    The version 1.01 will minimize this phenomenon as much as possible for the customer who use *istDS for this purpose.
