Improved camera support includes the following cameras: Canon EOS 7D, Canon PowerShot G11, Canon PowerShot S90, Leaf Aptus II 5, Mamiya DM22, DM28, DM33, DM56, M18, M22, M31, Nikon D3s, Olympus E-P2, Pentax K-x, Panasonic FZ38, Sigma DP1s, Sony A500, Sony A550 and Sony A850.
There are a number of bug fixes also. An issue limited to Mac customers using PowerPC hardware has been corrected. The issue, introduced in the demosaic change to address sensors with unequal green response, has the potential to create artifacts in highlight areas when processing raw files from Sony, Olympus, Panasonic and various medium format digital camera backs. In addition there is a fix for a visual glitch on Snow Leopard in loupe when panning.
The additional camera support is not available for Lightroom 3 Beta, but users can access this functionality using the DNG Convertor.
