I have a 10-150mm T2.3 Angenieux zoom in bayonet mount that I will be using for the Arriflex 16 SRI and Arri 16SB. Although I have owned many Angenieux zooms all which performed beautifully, this is the first one I have ever owned with the dreaded "auto-iris" pins (only the Zeiss 10-100mm T2 & T3 lenses have this feature). I am not sure why they made these "auto-iris" pins in the first place since every cine technician that I have talk to tells me they barely work and it's best to disable auto iris by removing the pins. Can anyone explain why they do not work well on the Arri SR cameras?
I would like to do it myself but this may be complicated (I heard it's very simple just remove the back screws and the pins "fall out") -I am not the most mechanical person in the world I admit, is it better to have cine technician remove these? Thanks!
