Report Arri Alexa 35 Won’t Accept Denecke JB-1 in Cameras... love them, hate them Posted August 30 Had my first issue with this today - mini 35 and a mini classic side by side. 2x jb1’s. Followed the very helpful instructions above to letter and no luck on the 35, but the older mini grabbed it right away no issues at all. just got a set of ambient nano-lockets but getting used to the blinkey lights and not knowing exactly what is happening without a screen is not the greatest under pressure. Once i checked my cheat sheet and got it going, nanolockit on mini 35 worked perfect. 1st n 2nd ac’s both found the note about a certain firmware i believe in the camera not working with the jb1, and the lower tc level output mentioned above could also be a factor. Nanolockits are good to have!
