hallo,
dabei handelt es sich um ein bekanntes Problem früher Seriennummern.
Zitat von der erst kürzlich besprochenen Review

Zitat:
Some very early purchasers of the A2 have reported a diagonal noise pattern. It turns out that this artifact varies in seriousness from camera to camera. It appears to be caused by some form of electronic "leakage" from within the camera's circuitry that "beats" with the image at a fixed frequency.
Thomas Knoll, the author of Adobe's Camera RAW utility for Photoshop CS has identified the problem, and "fixes" it in an upcoming release of Camera RAW. This means that any shots taken in RAW mode with an A2 that exhibit this beat frequency noise pattern can be automatically cleaned up when the file is converted by CR. This version of CR is currently in beta testing, will likely become available to registered Photoshop CS users some time in the second quarter of 2004. There is no cure for JPG or TIFF files that display this problem.

In discussion with a technical representative of Minolta I have learned that it was only the very earliest batch of cameras that display this problem. All subsequent cameras have had a firmware upgrade. You can check your camera by looking at the Firmware version number. Press Menu and go to the Blue Set up screen #1. Hold down the center OK button on the multicontroler and while doing so press the Info button. This will display the primary version number. Now, with that screen visible press the AEL button and the Info button again simultaneously. This will show a screen with various numbers. The upgradable firmware version is the first set of numbers displayed.
The original version which had the problem is r028. The one that fixes it is r034 or higher. If you have this very early version of the software, contact Minolta about getting an upgrade.
Also please note that firmware upgrades can be downloaded from various Minolta web sites. But be careful. Do not download a version from a web site in another geographic region. For example, Americans should not download a firmware upgrade from Europe or Japan. You could turn your camera into an expensive paperweight, and this will not be covered by warranty.
