If you just can’t wait for official RAW support for your Sony a6500 there is a way to change the EXIF data of your files so that RAW converters think they are opening Sony a6300. Tom Goetz put together a scrip to help you do it quickly with ExifTool that you can download and get directions of how to use here. From what I have read the files open perfectly so I do not think it will be long before we see full support of the Sony a6500 by the majority of converters.
