That camera requires at least Lightroom 4.3 or Camera Raw 7.3. Camera Raw 7.3 is only compatible with Photoshop CS6. So your choice is to at least upgrade your Lightroom, which will work with your version of Photoshop. Or the other choice is to use the DNG converter to create DNG copies of your raw files. But having Lightroom 3.5 is really limiting your capabilities when compared with what is available today. The choice, however, is yours.
