BP-8 Bridge plate connector
With this BP-8 Bridge plate connector installed on your BP-8 you can directly click in your Alexa mini setup with the Railway plate system and use the 19mm rods from the BP-8.
MAP-1 Alexa mini bracket from cam-jam is required to get the correct height of the rods.
Arri´s MAP-1 is too thick.
A riser plate for Sony F5 /F55 / Venice is available here
This is ideal when switching from a prime lens in steadicam or handheld mode to a large zoom lens.
