Canon bestätigt Probleme mit dem EF 70-300mm f/4-5.6 IS USM


Canon hat auf seinen amerikanischen und japanischen Supportseiten eine Servicenotiz zum EF 70-300mm f/4-5.6 IS USM veröffentlicht. Bereits seit einiger Zeit ist in zahlreichen Foren von Auflösungsproblemen in den Rändern und Ecken bei Verwendung dieses Objektivs bei Hochkantaufnahmen die Rede. Bisher weist Canon allerdings nur auf das Problem hin, kann aber noch keine Lösung anbieten.

To Customers Who Use the EF 70-300 f/4-5.6 IS USM Telephoto Zoom Lens.

Thank you very much for your patronage of our products.

We have recently become aware of a phenomenon in which some images captured by the EF 70-300 f/4-5.6 IS USM lens appear in insufficient resolution. This phenomenon may be seen at the edge of the frame at the 300mm setting when the camera is held vertically. We have been studying the symptoms of this phenomenon in order to determine its precise cause and to develop an appropriate remedy. We will inform you on this Web site as soon as this remedy has been decided, which, at this point should be by the end of June 2006.

We are very sorry for the inconvenience this phenomenon represents for customers who use this lens and appreciate your patience as we work to resolve it.
