I have lightroom 5.7.1. My camera is not listed in this version. It says I need 6.5. Can I update my current version or do I need to download the new program?
You have to PURCHASE either Lightroom 6.5 or Lightroom CC 2015.5 (or later, the current version is 6.8/CC 2015.8).
The free alternative is to use the Adobe DNG Converter, convert your RAWs to DNG, and then import the DNGs in to LR 5.7.1.
