The mount is the same material throughout. I made a quite deep scratch :) definitively not just metal coat on something else inside.

The material might be aluminium.

Ok.....but mount on PD 10-30 zoom looks 100% identical to the 18.5 mount.
Could we conclude that no mounts are made of metalized plastic?

from ebay :o :o :o
its injection molded but it doesnt appear to be made of plastic, probably some kind of nickel alloy. ::) the same material used on some metal internals of ai-s and later lenses

Ok.....so the reason why the 10/2.8 feels more heavy might be that this mount is chromed brass....so a "real" Nikkor mount on this one?
And maybe also on 32/1.2 and 70-300?

Is there a possibility that Nikon has changed the material from start to end of production, as mine 18mm really feels like plastic?
Bought late in the Nikon 1 history ;)

possible... ::)

this alloy actually feels like plastic. if you read my articles you will see a greyish metal inside of some ai-s and later lenses. this is the same brittle alloy if i am not mistaken, definitely zinc-nickel or most likely :o :o :o

This is a 10-30mm Nikon 1 lens mount - Looks like injection molded metal zinc-aluminum alloy then the mount face is finished on a CNC mill for accurate dimensions.
Strong, light and well suited mating surface for the cameras mount surface.
By far strong enough for the small light Nikon lenses.

I was quite disappointed when I found out that my Nikkor 1 lenses has mounts of painted plastic......but it seems not......so a bit more happy with my lenses......
What material is the mount of the 10/2.8?    .....chromed brass?

I use a 40.5 to 52mm step-up ring on my 18.5 mm lens in order to be able to use standard 52mm filters (e.g. polarizer and L37c filter).
Then a lot of standard Nikon lens hoods can be used also. A 40.5 to 52mm step-up ring is cheap. I use a standard 52mm Nikon lens cap for the lens.

The dedicated 18.5mm hood has a thread for attaching 40.5mm filters or adapters. The usefulness of this particular hood is that you have good flare protection and the camera looks like a cheap consumer-grade one (very useful for on-street photography). I did the 40.5 to 52mm step-up ring trick with the 10 mm lens, and I could reuse an old foldable Nikon rubber hood. With the unextended hood, a 1V1 + 10mm will have a humble look, unlike one with a full size protruding hood. Either way, nobody will consider you as a paparazzi, or as a potential robbery target...

this lens is my favorite for the V1 , the f1.8aperture allows me to keep the ISO below 800 , a bit bulkier than the 10mm f2.8 but way sharper

the ergonomics of my v1 can be annoying, but I've learned to live with it
with the X-T3 I keep forgetting where things are and the menus are a pain to scroll through
the best is still my D800

With the 18.5 the image quality is better than photos from a mobile

Where do I find information for which material the bayonet is made of?

What is "funny" is that I am able to make a mark into the bayonet shinny part with my nail. But maybe the shinny part is a thin coat?
And why do Nikon coat it if it is made of metal?

The mount on FT1 adapter is very different.....it "smells" of metal from far distance :-)  it feels like several steps up in quality and I would have liked this bayonet mount on Nikkor 1 lenses......

plating helps create a protective coating :o :o :o and also make it look "decent" ::)
