looking at all the videos on YouTube they show a lot of people tethering. And at first I was excited to see they were using C1Pro, until you look close and they are using JPG mode. I'd love to see one good review of tethering with whatever the best option is for raw shooting. I remember when the Leica S came out not long before I bought my H4x/Credo kit and seeing how slow the tethering was was the main reason I never even considered it.
