It's the other way round, Klaus: For a 130 grams lens, a metal mount is overkill. And if I remember what I saw inside my broken 56/1.2 Fujinon with metal mount, I have to say, a metal mount fixed on plastic with 3 tiny screws is also no guarantee for durability ![Wink Wink](https://forum.opticallimits.com/images/smilies/wink.png)
