The contemporary trend of sterile optical perfection at any size cost has truly gotten out of hand!!!  :o haha

The only positive thing is that this particular lens can be made as sterile as possible without any "character".  :D

Expect one from the Chinese very soon.
Probably won't focus to infinity tho .. I think I read that the register distance is only 15mm on the new telescope!

:p

An adapter with the focus reducer should be possible.  But I'm not sure if the focal length can be registered in the camera for the IBIS to work properly when the combo is handheld.

Read the comments!  Lots of humor, referencing things like selfies, KR, DP Review, common online photo forum behavior, past LensRentals posts, etc.

Apparently this is part of a larger optical system where the main element is a mirror.

Does it cover fullframe? How well does it do in infrared and is light weight? I hope it fits in my sling bag.

Yes, apparently it is placed right in front of the combined multiple sensors facing the mirror.

If you are as tall as Gulliver, the lens should be even pocketable!
