1-you need to download Leaf Raw Converter
2-you need to set up automatic import in lightroom, define a watched folder to store the .mos files that you will convert using LRC. Otherwise you'll have to copy the files after the conversion, that will double your work.
3-open Leaf raw converter, select the card where your images are, and select the lightroom folder where they will be copied. Click "save compressed (lossless)" and Convert.
4-if you are shooting thetered, there is no need to do all this, you just need to use Leaf Capture to conect the camera and then select the same lightroom folder to transfer the images. No need to use LRC.
Hope it helps
P.S Lightroom must be running when you use LRC
