Interesting, thanks, I didn't realize that. I had come across a reference that said these were all point and shoot but clearly that's wrong. This is what's great about Nikonites, no matter how much you *think* you know, you can always learn something new

Yes, that is awesome thing about Nikonites. especially how some chose to jump to conclusions and put someone down so readily with labels without even trying to find out the truth. And coming from a moderator of the forum, makes it even more interesting.

Take care guys. Have fun and enjoy yourselves here.

It wasn't so much your assertion that Nikon used plastic, rather it was your Oliver Stone-esq attempt at making it something very secretive. So secretive that you had signed a non-disclosure agreement and yet Nikon puts this very same information on their website. So yes, I agree with you, it's been VERY interesting....

Dxox testing or whatever the heck that place is called is about as factually relevant as Oliver Stone...Pure marketing manufacturer funded ca ca to make you go out and buy the latest greatest cameras and lenses IMHO...Plastic lenses are just as good as glass maybe even better...and to further enlighten you folks most camera glass made nowadays is Wal Mart revolution "molded" glass (read cheap made in Taiwan crap) as opposed to old school ground glass...But hey whatever gets the job done right?

This hasn't changed anything. The contention was that Nikon and other manufacturers produce lenses made of plastic and that still isn't the case. When one adds a UV-curable resin film of 0.05 to 0.2 mm thick (that's only 50 to 200 µm) at the thickest part to the surface of a glass element in order to add an aspherical correction to the element, that is a hybrid aspherical lens. It is an aspherical, molded coating added to as surface of a glass lens. All the lenses listed here with hybrid elements are made in that way. The elements themselves are still made of glass, not plastic.

Show me a lens design with a lens made entirely of plastic because that is what was clearly meant.

That's a very good point. I can't imagine there's such a thing as a non-disclosure agreement that would disallow a person to post a link but hey, what do I know?

And just an additional note instead of editing my post.....the hybrid lens design utilizes a resin layer on the glass element. Yes the resin layer has optical properties but it is basically a coating with differential thickness to mimic the qualities of an aspherical surface in order to save costs on grinding/polishing. There's a difference between a layer and an element (lens).

His reference to the NDA was to imply that he had information directly from industry that was proprietary and that he could not disclose, which didn't make sense if he is speaking about lenses that have already seen production.

lol this thread began to derail pretty early on for this forum, but anyways, my newbie take on this-

quite a few modern plastic formulas are tough as literally nails, but im almost completely positive its nowhere near camera lenses due to "cost".

only comparable lenses i have so far is my 1966 50 f2 and 35 1.8g. is metering and af nice to have, esp for sports? heck yea! does lens feel better than old 50? hardly. optically? i learned what fringing is for the first time with the G, lol.

if i could get metering/cpu on oldies, id be all over them, but its just indispensable to me about half the time, so im stuck using newer glass to avoid missing shots.

Yeah but the sensor on the back of your eyeballs and the processing unit they are connected too is WAY more sophisticated than any camera...so you can get away with plastic easier...LOL

Hey do you have Nikon glasses? Did you know Nikon makes glasses? I didn't until a few days ago...
