More info about lens model and adapter please. Has this been reported to our support team officially?
Its not been reported to the support team, only mention on this forum.
BMCC6K when using Sigma MC-21 L to EF adapter the following Canon Macro lenses iris fluctuates depending on focus distances.
Canon EFS 60mm f2.8 Macro
Canon EFS 35mm f2.8 Macro IS STM
Canon EF 100mm f2.8L Macro IS USM
All of these lenses the iris are fixed and does not fluctuate with focus distances on any Blackmagic cameras with EF mount or cameras with M43 mount with Metabones EF adapter. With Canon cameras the iris also does not fluctuates with these lenses.
