They are very, very worth it.

Google "tour Nikon lens factory". Several popped up, you can tour the Sigma & Fuji factories on how they make lenses and bodies.
BTW: They are only going to show you only a very small portion of their manufacturing processes, there are lots of proprietary stuff behind the scenes. Unlike the mistakes in US in the 70s & 80s where they gave Japanese engineers unfettered access to US manufacturing.

The videos are older, but look for the Canon lens manufacturing video. They start at the glass manufacturing process and go through the ginding and polishing all the way up the the final product.

Pretty cool

ETA: Here.

12K Is not too out of line.

I would love one. But honestly I would rather see them come out with a 600 in F4 or even an F5.

400 is a bit short for a lot of what I do, but the speed would be nice.

Thank you for the links. I'll check them out in the morning.

After seeing all the youtube videos on this lens the bokeh seems weird to me.

In my line of work, TV/film, $20k to $40k is the reality for high end glass.

Before HD in the late 90s a SD zoom video lens would easily top $14k.

Here is a nice Fujinon 75-400mm T2.8-3.8 for $96,000.

It’s best to just rent these.

They seem to be a bit more reliable and consistent.

F stops are what the lens should do. T stops are measured and calibrated for that light volume. At least that’s my understanding of it. So like buying a harbor freight caliper vs a fancy machinist one.

You sir, are correct.

T-stops are Transmission Stops, as in the actual amount of light that is transmitted through the glass, taking in consideration the light absorbed in the glass.

F-Stops are theoretical or mathematical stops with no consideration for light loss due to the glass.

No glass allows 100% transmission.
