Along with Photoshop Lightroom 2.0, Adobe released DNG Converter & Camera Raw 4.5 on Tuesday. The update added support for the Olympus E 420 and E 520 cameras.
DNG Converter & Camera Raw 4.5 requires Photoshop CS3 or Photoshop Elements 4.01 or higher. Using version 4.0 or higher of the plug-in will disable the ability to open camera RAW images in Photoshop CS2.
DNG Converter & Camera Raw 4.5 is free and available for download at the Adobe Web site.
