DNG pros and cons
I have been using lightroom 3 to process Canon CR2 files. I import CR2 + JPEG. However, Lightroom 3 does not support Sony RX100 .ARW format. I convert the ARW files to DNG and import. It is an extra step but now I wonder if it is a good practice to convert camera vendors' proprietary format to DNG. DNG claims to be an open standard. What is the pros and cons of DNG vs. camera vendors' Raw formats if I only use lightroom and not the Raw professing software comes with the camera?
