Lightroom (5.7) does not open files from my new EOS 5 DS. I have made an update, but nothing change. How can I install the camera raw 9 plug-in in LR ? It works with Photoshop CS 6 but not with LR. Do I have to upgrade to LR 6?
You can use CS6, convert CR2 to DNG or upgraed to LR6. You can buy from the following link. After clicking "Buy" change from Full to Upgrade; then select your existing LR product from the drop-down menu and the correct pricing will be displayed. Then simply choose “Add to Cart”
Or you can take a 30 day free trial via the Creative Cloud and convert the CC version to LR6 upon purchase and without any further installation.
You will either need to upgrade to Lightroom 6 or use DNG converter 9.1. There is no support, and will not be support, for that camera in Lightroom 5.7.1 or any other version of Lightroom 5.
