I got a chuckle when they showed the focusing on a Canon body @4:43. Although you can see the scene starting to focus Cosina never bothered to continue focusing until the triangles appeared and brought it into full focus where the triangles would line-up.
Nice to see that it has contacts and communication. I have a 35mm Ultron and it works great on an R5 v1 camera. It is a dumb lens. I always wondered if the focus arrows really work. Focus peaking never worked great for me. I rely on magnify now but options of new RF with comms is great.
