    Thanks to the advice on this topic, I've upgraded the firmware on the Metabones EF-to-BMPCC Speed Booster. The version on it was 2.4 something and it got upgraded to 2.9 something.

    I don't know if upgrading Sigma firmware will do anything.

    Focus and Iris interact with the lens. It just will not close beyond 9.5 leading to some very washed out daylight footage. Granted, I shoot in ASA 800 because it's the native ISO. I shoot RAW 24fps.

    My guess is I'm going to need some ND filters. Which ones do you personally use? Thank you all for being so supportive!

    Hi Denjin. This is normal behaviour - your lens is stopping all the way down, but the speedbooster has an impact on the displayed f-stop.

    Stopping a lens all the way down is generally not good for image quality. NDs are a must and there is lots of useful info on this site if you search.

    Ben is correct. The general go to is getting a Hoya IR cut filter to go with your NDs in order to negate the infared light that will turn your image a tinge of washed red. This is because regular nd filters only block the visible light leaving the infared which the camera interprets as normal red. You can get filters that are both nd and ircuts but they are more expensive. Hoya is a good brand for a balance of price and quality.

    I do have a Hoya UV/IR cut filter. I'm thinking of getting this https://www.amazon.com/gp/product/B00XZVPPPG/ It's an adjustable ND filter.

    The ones by Hoya are not bad, but keep in mind that, being based on polarizers, all variable NDs have some side effects.

    Unfortunately I didn't think about NDs when I bought the camera and got the Hoya UV/IR-cut, so I already have an IR filter in place, I'd need just an ND.

    Use the following. They're fantastic tools when moving from indoors to outside.
