It’s increadibly sharp for it’s age, but the auto focus is very slow, because it doesn’t have it’s own motor as far as I understand and relies on the motors from the camera body.
But we have out fair share of Mao and Stalin lovers and Xi loveboys. It’s very simmilar. But I guess they are mostly contained to one or two instances.
It’s not some force keeping them the same, it’s no force changes the speed of the moon. From my limited understanding the moon was created when a smaller planet crashed into the earth:
They both got the same momentum, therefor they started rotating at the same speed, once per day.
There is nothing out there which would be able to change the speed of the rotation of the moon. There is also nothing which would change the speed of the rotation of the earth. Therefor they keep spinning at the same speed.
