You own Adobe Creative Suite 4. Recently you upgraded to a Canon 5DMK11 full frame camera. You don't like their conversion software at all.
Your other digital camera would place SDHC directly to DNG, which made it easy to work from. How do you have that Canon RAW converted to DNG without excessive expense or purchasing more software? You can download and install Adobe DNG Converter 5.1 update for free.
Basically, you convert your RAW camera files into DNG format with that converter. You should then be able to edit them with your Adobe creative suite 4. This Adobe DNG Converter, is a free utility that converts files from more than 200 cameras to DNG, enables you to easily convert camera specific raw files to a more universal DNG raw file.
