Have you tried the standalone DNG converter to see if it might be more efficient in performing the conversion process?
I have not tried but I may give it a go, do i down load that sperately?
Yes. Windows or Mac? I will give you a link.
Do I convert to DNG and then load into LR?
Yes. The DNG converter is an independent, standalone program. You run it first and convert your images to the DNG format, and then simply import the DNG files to Lightroom. One way I like to use it is as the download software, using the SD card As the source and a folder on the hard drive as the destination. Then the conversion is done during the transfer from the card to the computer. Here is the link to the latest version:
And here is a brief video on how to use the DNG converter:
Take note that the DNG converter works on the Folder level. It will prompt you for a folder containing raw files. Choose the FOLDER, but don't open the folder. If you open the folder the DNG converter will indicate that there are no raw files to convert.
thank you I will give it a go tomorrow
