Plastic molded (PMo) aspherical elements should make lenses cost less

Considering what EF and RF lenses cost the consumer do you believe that those prices are justified when the manufacturing of plastics components is easier as opposed to the manufacturer of glass elements. 

 The manufacture costs of anything plastic on a mass scale is lower than that of glass or metal.

Canon uses plastic elements in it's L lenses do you believe it justified the high cost. 

I feel that any cost savings that company enjoys should be passed on to the customers.

Having spent most of my career working in the in the chemical and plastics manufacturing business, I know a little bit about The cost of raw polymer as they go to the manufacturer before they become a final product. 

They are sold by the railcar full at fractions of a cents per pound.

So you know how to use and read Ai. Good! 😊

It is a thin line of distinction of the word 'lens' when talking about the resin 'lenses'. It is more of a coating than a true lens. The non-L lenses do have real full on plastic lenses. The main optical elements in L lenses are all glass not any plastic.

Disclaimer. Now that being said I am not completely up on all the latest or new products in the R- series of L lenses. There may be a new lens out I have not used or seen. I don't keep up on that as much any longer.

"Yes, and?"

Ai has made a lot, millions, of people overnight experts. Voilà. No experience necessary just read it and repeat it.

Your statement of the obvious aside, AI has an astounding ability to merge correct information quickly and respond to a question in nanoseconds drawing on the sources a person could spend time looking for if they were to research a question.

In life a person can choose to be a Luddite who distrusts "newfangled" things that "the kids these days" invented, get their pitch forks and burning torches, and chant "AI is bad" over and over again as they burn the letters "A" and "I" in effigy in the town square, or they can choose to understand and benefit from the informational leap that AI is. I stand squarely in the latter group often chuckling at the "think they know betters" who hate AI but use it to edit their photos in post.

And just because I responded to your statement, don't make the mistake of thinking that I am responding to you specifically.

"Plastic" is a general/umbrella term rather an a specific/technical term.

Talk about a flare the dramatic!

"AI has an astounding ability to merge correct information.."

And incorrect info. Ai or any resource on the ole inner web, is only as good as the sources are. GIGO, garbage in and garbage out. It's not that I don't trust Ai, I don't trust anybody so, I question everything. You don't. You select and you believe. I much prefer to rely on my own personal experiences gained over a lifetime of successes and failures. 

It is a fact at my age I am posting and replying less and less as the newer stuff comes online. But, and a big but, some things don't change or change very slowly and that's where personal experience is better than any Ai.
