The camera requires Camera Raw 8.2 or newer. There isn't a version of Camera Raw that is compatible with your version of Photoshop that will support the native raw files. You can download the latest DNG converter and create digital negative copies of your raw files that you can use with what you have now. Or you can subscribe to the creative cloud photography plan ($9.99/month) and have the latest versions of Photoshop and Lightroom. Or you can purchase Lightroom 5 and had it to your workflow.
