Junk.

It is pretty impressive for a camera lens with that zoom factor to get
even remotely close to diffraction limited at the long end. There was a
time when they struggled to do 3x zooms reliably not all that long ago.

If only the world knew the way you hapless mathematicians think so your 3X brought to mind the book by the English mathematician who poked fun at exotic speculation that eventually showed up as Alice shrinking and expanding -

The idea of 3D+1 applied to the celestial arena is fantasy and the fact that I can easily deconstruct the intrusion of mathematicians into astronomy via their concepts of time (really timekeeping) and complete perspective failure is meant to bring not only astronomy back to the population of this planet but also to return mathematics to a proper role.


It may not be true in terms of the fictional book as a reaction to mathematicians but the evolution of mathematics in 20th terms of time and space as distinct from the terms Newton originally applied, falsely as it turns out, demonstrate why it is now all too much with nothing but non visible voodoo coming from your and your hapless colleagues.

Strange people who became dominant but that time is ending.
