No, what I would say is that these are lenses that require a huge amount of highly skilled labor to manufacture. And it takes big bucks to ramp up a manufacturing process for them as well as do the original research and design. Bottom line, I think these are really hard to make to a high standard.

Take a few minutes to watch the video of how they make these things, it is a crazy amount of manual labor. Assembly is by hand, and I'll guess that quality requirements kick out a good percentage of units after testing.

I think this is the older, easier to make model.
