I purchased the 180 degree ArduCam kit from Amazon for my HQ camera. The original CS adapter that came with the HQ camera threads effortlessly onto the backfocus ring, but the M12 adapter that came with my ArduCam kit will only screw in to the backfocus ring about a half-turn and then stops.
I have another C-lens that screws effortlessly into the backfocus ring.
The ArduCam M12 adapter screws effortlessly into the HQ’s CS adapter - but using the CS adapter prevents me from bring the 180 degree lens into focus.
Am I doing something wrong, or is there a chance that I was sent the wrong M12 adapter (for CS rather than C?) From the videos and diagrams on ArduCam site, it would appear that the M12 adapter for the 180-degree lens is supposed to screw directly into the C-backfocus ring.
Thanks!
