Does anyone have pictures or directions or a manual on how to assemble this lense. I took it apart a while ago and I still have all the parts I just don't remember how to put it back together. Where does the small metal plate go and the spring etc.

Sigma 24-70mm F2.8 EX DG Macro: Lens dropped into salt water

Wed, 04 Sep 2019 12:08:30 -0700

Hey community,

I dropped my mirrorless camera and my zoom lens into saltwater earlier today. They were both completely submerged for 15 seconds.

I did not try turning the camera on after getting it out of the water.

I immediately dried it and removed the memory card and battery.

Is there anything I can do to salvage the lens?
