[@Bensch.Fotografie]

Information about the coatings or materials can be easily optained through materialanalyses for most products. Processtechnology is a well hidden secret for most factorys, and that's for a good reason, since often times the problem is not "what" to produce, but "how", process wise. So If you are familiar with processes of this kind you get quiet alot of information.

[@mrrcassidy]

I have a bag full of art lenses. They are beautiful. Better than my Canons.

[@peoplez129]

The new mounting systems changed the whole game, because lenses can now be mounted closer to the sensor, which means more sharpness and less corrections needed for the issues that arise from mounting the lens further from the sensor. So while lenses can be tack sharp even with the old mounting system, the fact is that the new mounting system is miles better for lens quality. This also means they don't have to craft lenses as high of quality as previously. So technically older lenses are crafted better, but they perform worse because of all the issues that arise from the mounting distance.

[@captiveimage]

I am now no longer surprised at the cost of these lenses. The amount of manual labour, and the precision and care taken by all the workers to make these fabulous pieces of technology are astounding. I've watched manual production of items before, but the difference between those (no names mentioned) who's workers appear to be simply doing a job, and these guys and girls who appear to be putting so much love into their work is quite disconcerting.

Wow, it's incredible how such craftsmanship is done on an industrial scale. Props to the factory floor workers, they put a lot of dedication into make sure the quality is top shelf!

１年に５，６本くらいレンズ買ってるカメラ好きですが、これだけの工程を経ているとは知らず。 もっとレンズに感謝して使うべきだと思わされました。

Thank you for sharing this video. It's very nice to see how high-quality the production is and what it takes: people, technology and know-how. Keep going, competitors don't sleep.

Such a beautiful job. Thanks for all of those so careful people who make such incredible lenses. Really appreciate your job.

i had no idea the letters were handwritten. that is some skill.

[@Hydrazine1000]

(As someone else mentioned already) The letters are already engraved. The manual work is only letting white paint flow into the recessed engraved letters. This still requires skill and good eye-hand coordination, but it isn't free-hand painting that you see here.

I owned a Sigma 8-16mm ultra wide, it is one hell of a good lens for the price. And feels very solid too

この様な動画を海外のチャンネルでも見るが、日本の工場は安心して見られるってのはスゴイなぁ～といつも思う。

From now on I will treat my lenses with a lot of respect and love. This is a lot. Well done Sigma for giving us an insight into how your fine optics are made.
