Canon statement: To Owners of the EOS 5D Mark II Digital SLR Camera Thank you for using Canon products. We have learned that some users of the Canon EOS 5D Mark II digital SLR camera have identified two types of image quality phenomena that appear under certain shooting conditions. “Black dot” phenomenon (the right side of point light sources becomes black) Vertical banding noise We are currently investigating and analysing the causes, and examining measures to reduce or eliminate these phenomena by providing correction firmware. An announcement will be made on www.canon-europe.com as soon as measures have been determined. Details of the phenomena and shooting conditions under which they are likely to occur are as follows. 1. “Black dot” phenomenon (the right side of point light sources becomes black) When shooting night scenes, the right side of point light sources (such as lights from building windows) may become black. The phenomenon may become visible if the images are enlarged to 100% or above on a monitor or if extremely large prints of the images are made. 2. Vertical banding noise If the recording format is set to sRAW1, vertical banding noise may become visible depending on the camera settings, subject, and background. ▪ Vertical banding noise is not noticeable if the recording format is set to sRAW2. ▪ Vertical banding noise does not occur if the recording format is set to RAW or JPEG. ▪ Noise can be reduced if C.Fn II-3: Highlight tone priority is set to 0: Disable. Canon apologizes for any inconvenience caused and thanks photographers for their patience. |

比问题本身更严重的是，佳能公司在这次事件的声明中只对欧美的顾客致歉，而对亚洲国家的声明中故意删除了道歉的字句。 http://forum.xitek.com/showthread.php?threadid=586097 在佳能对此作出解释和更正之前，大家应该抵制佳能的任何产品。 |

问题不算大。
感谢您使用佳能产品。 我们了解到一些佳能EOS 5D Mark II 数码单反相机的用户指出，在特定条件下拍摄的图像有以下两种现象。 1. “黑点”现象（点光源右侧变黑） 2. 纵向条纹噪声 我们正在调查和分析原因，通过新的固件减轻和消除此现象。在决定了解决方法后，会及时在佳能网站发布公告。 这些现象的详情以及容易出现这些现象的拍摄条件。 1.“黑点”现象（点光源右侧变黑） 在拍摄夜景时，点光源（例如，来自建筑物窗户的光）的右侧会变黑。在显示器上放大到100%及以上尺寸察看时或者用特大幅面打印图像时，可见此现象。 2. 纵向条纹噪声 如果记录格式设置为sRAW1，依据相机的设定、被摄体和背景，可能在图像上出现纵向条纹噪声。 ▪ 如果记录格式设置为sRAW2，纵向条纹噪声不明显。 ▪ 如果记录格式设置为RAW 或JPEG，不会出现纵向条纹噪声。 ▪ 如果将C.Fn II-3:高光色调优先设置为0：关闭，噪声可以减少。 我们一直努力为用户提供高质量的产品，非常感谢您的支持和理解。 |
C'est la vie
