This camera seems to be pretty new and I believe it was released recently and so, the support for these raw files is not yet available in Lightroom.
You need to wait for the next camera raw update though the update would be only for Lightroom 6/CC but not version 5.
You can use Adobe DNG converter to convert the raw files to DNG and access those DNG files in Lightroom.
i tried and copied the raw-files to my harddisc. Then I started DNG Converter and opened the import-Folder. But DNG Converter can't read respective does not list the raw photo-files (.srw extention) in the import-folder.
Thanks for the update.
You should try the steps mentioned by 99jon.
Yes, that works!!!!
Thank you very much!!
Thanks for letting me know that, ssprengel. I think I mistakenly read year 2015 as 2016 in the release notes of Samsung NX 330.
