[BUG] BMPCC 6K - BLE issue with iris on Sigma & Canon lenses
Posted: Fri Aug 16, 2019 4:35 pm
Hi there,
I just had the chance to test the BMPCC 6K with two old Sigma EFS lenses.
The camera worked completely fine.
Iris on the front wheel, etc. etc.
Then I tried to control the camera via iPad with the official Blackmagic Camera Control app.
Here I found the following issue.
The iris value is not shown correctly.
It displays always f 1.2 even though the lenses were not that bright.
While moving the slider the correct value is shown and the iris in camera is adjusted correctly.
When I stopped touching the slider it jumped instantly to f 1.2 on the display without changing the actual iris in camera.
But if you touch the slider again the iris will go fully open for a moment before going to the designated value.
This causes a weird effect in the recording.
When I stopped touching the the iPad the slider jumped to f 1.2 and so on..
BTW: The third party app on the iPhone was showing the same issue.
Is this a lens incompatibility or an easy to fix flaw in the BLE firmware?
Can anyone confirm the issue or mention lenses that do work fine?
Thank you in advance!
Chris
