I linked in the other thread on the same Nikon 1 lenses 
As always you can rely on Rolands pages for such information

PM is indication of Plastic Mount

I see......and 18.5 has the indication "PM".....and that is 99.99% correct :-)   .....it would also be my best guess.....but.....maybe it is still metal......below the coat.....

Different materials are chosen for wear resistance and mainly to prevent galling

According to Roland's Bible, the featherweight 18.5mm (only 70 grams, compared to 77 g of the 10mm/2.8 and 235 g of the 32/1.2 ), can safely get away even with a plastic mount. I would not worry too much!

It's very comprehensive and 99.9999% accurate,,,

That implies only one error in one million entries. I don't even have that many data points, and I am sure there is more that one error or inaccuracy

here's the review

[Gerhard2006]

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

I agree with you Armando that's why when I bought my V1 I bought the Nikon grip and later got even a cheaper one for it on eBay. The original grip I adapted to my J5 and cut off the little snibs(for lack of a better term) so the screen would still tilt.The grip made the camera so much more enjoyable to use. Regards Gerry

Big fan of the 18.5 1.8.. Just got into the N1 ecosystem at the end of January after picking up a V2 with 10-30 and 30-110 to play with... Now, somehow only just over 2 months later,  I have a V2, V3, 6.7-13, 10mm, 18.5mm, 10-30 pd and non-pd, 30-110, 10-100, SB-N7, GN-N100...  "Just" missing the 32 and the 70-300.... Like, those two lenses will double the cost of my entire setup.

Anyway, big fan of the 18.5mm. what a nice closeup performance.

Richard,

I think that with the lack of durability of the N1 series lenses, it's always good to have a backup... I've got two of each of the cheapie lenses... 10, 18.5, 10-30 and 30-110...  These things really are less consumer grade, more consumable grade.
