I am not familiar with Sony camera models. Here is a list of all cameras currently supported by Camera Raw. I didn't see the model number that you typed, so maybe you can verify and compare against the list:
If you are talking about the A7 II, then you need Camera Raw 8.7. It is only compatible with Photoshop CS6. If you use Lightroom, you would need at least Lightroom 5.7. Or you can download and use the DNG converter to create DNG copies that you can use with your current software.
I have the A7rII and had the same problem. I downloaded Sony PlayMemories and go through it to Photoshop and problem solved. Don't know why, just that it worked for me.
