Re: Can anyone explain me the aperture mechanism FA28-105 F3.2-4.5 IF-AL

Thank u all for the replies.

I'll try the same npw with my old fa* 24-70f2.8 which I also rarely-seldom use.

I think now I know what the spring is for: keeping the aperture open in 'A' position of aperture-ring to provide ttl. Removing de tiny bal which enables blocking/locking/clicking might not change anything else, I know now.

Thx 🙏😀
