Learn Digital Photography - A Digital Camera Review

There have been a lot of comments made recently regarding 'Black Dot' and 'Vertical Banding' issues by owners or potential owners who have been scrutinizing the camera's output. The company says it is investigating both issues and will work on 'measures to reduce or eliminate these phenomena.'

I 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, being 1 - "Black dot" phenomenon (the right side of point light sources becomes black) and 2 - Vertical banding noise.

They are currently investigating and analyzing the causes, and examining measures to reduce or eliminate these phenomena by providing correction firmware. 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.

I am personally quite impressed with how modern day giants deal with customer inquiries and this type of post customer service should always be taken into consideration when purchasing a digital camera or any other consumer item.
