Plastic or metal bayonets on the Nikon 1 lenses?

There was a discussion on a camera forum the other day about the type of bayonet Nikon is using on the Nikon 1 lenses which made me a bit curious. Some people claim that the majority of the lenses have plastic bayonet, others claim that some of the lenses have bayonets made of two parts, a metal ring and a plastic tube. To find out the truth I decided to check out the 10-30mm and the 30-110mm lenses.

After removing the screws and looking underneath it is clear that these two lenses have a 100% plastic bayonet, made out of one single molded piece. The circular marks underneath are typical marks after the molding process.




 
Never the less, it seems to be high quality, and while not as good as a metal bayonet could be, it doesn't really matter as long as it works. It is amazing that the surface still does not show any signs wear and tear, and it still looks like metal.

Please note, I have no idea if the majority, or perhaps all the Nikon 1 lenses have plastic bayonets, only these two.

The coating is pretty well done, but the fact that it is plastic will stop me from using my ring flash on those lenses, and I would advise every user of the V2-F1A to not use any ring flash on those lenses any more.

On the other hand, the FT1 is really well made and is definitely 100% made of metal, so if you intend to use a ring flash with the V2-F1A I would advise to use a real macro lens together with a ring flash.
