I suddenly started having a problem with RAW files being blurry after importing them to my PC. On the camera, the images were sharp but the imported RAW files were blurry. I was a bit alarmed until today when i realised that this was only affecting images imported when using a USB-C SD card reader. When i re-imported them directly from the camera, the images were fine and sharp. Does anyone know why this is? I bought a genuine SD card reader from Scandisk along with the SD card..... a very odd issue. I'm going to try with another SD card reader....
