100-300mm Iris Issue

[Michael Reichmann]

I have seven Panasonic M4/3 lenses and all work properly with the AF100, except the 100-300mm.

With this lens neither Auto Iris nor Manual Iris work. But, the lens works fine on my GH2.

I've spoken with Uwe Steinmuhler who also has the 100-300mm and his works OK, so I'm guessing that it may be my particular lens.

Anyone have any thoughts or experience with this before I call Panasonic support?

I've got that lens and it works fine on mine.

First thing I'd say is inspect the electrical contacts on the back; I have no idea what exactly they do, but if one is dirty and it so happens to be the iris one, then maybe cleaning it off would help. Otherwise, if you can't get it to work, then yeah, ask a service center about it.

Thanks Barry. That was the first thing I tried.
Guess it's into the shop for that lens.
