January 9, 2009: Canon has released a firmware update for the just-released EOS 5D Mark II DSLR camera, which 'improves and mitigates' problems detected when the camera was first released.
The following fixes are provided:
1. Addresses the "black dot" phenomenon (where 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 greater on a monitor or if extremely large prints of the images are made. This firmware improves and mitigates this phenomenon.
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. The firmware improves and mitigates this phenomenon.
On its website, Canon advises users of the bundled Digital Photo Professional and Picture Style Editor applications to update both applications as well to prevent a magenta shift in dark, low-contrast areas in the images. The firmware update can be downloaded from Canon's website at http://web.canon.jp/imaging/eosd-e.html. New versions of the software (DPP 3.5.2 and Picture Style Editor 1.4.2 for Mac and Windows) will be available from Canon's Australian website via the Set up page at www.canon.com.au/products/cameras/digital_slr/eos5dmkII_support.aspx.
