I have the same issues with my Sigma Art 50mm F1.4, so it is definitely a Metabones problem.

Interesting findings! Any updates on how to approach this problem?

Thanks for the video. I'm struggling with the same issue. Under f/1.8 there's magenta color shift indoor or outdoor. (so not a flicker issue) I thought that I had a bad adapter, so I bought another one, but it behaves the same. Did you find a solution or workaround?

I have the same problem for my metabones speedbooster for bmpcc. Have you reached out metebones about it?

[@WarrenGoldswain]

yup, they asked me to perform new tests for them, but since I submitted my findings they have gone quiet.

[@shukakizawa]

thanks for replying. Strong magenta tint appears as it gets wide open on all of my 3 Rokinon lenses. I'm thinking to ask Metabones to change it to a new one if it's not how it's supposed to be.

I am still waiting for their response.
