Just called Kiitos.  Kiitos is a repair shop founded by the ex-Nikon repair persons.

The repair person on the phone said that the rear group of Snoogly's 16/3.5 fisheye is very probably suffering from the balsam separation.  He further explained that the rear group of this fisheye consists of two glued elements and is sensitive to the shock or any sort of force.  If such force is applied, it is prone to separate which is irreparable.

If the seller sold the lens as "junk", I would say he is at least honest.

I hear you :-(

I can’t even remove the offending group though :(

Warm the whole assembly that you have removed from the lens, maybe in a warm oven?

Well, I sent photos of the damage to the Taiwan repair man, and he said he is confident he can repair the grouped element. I will send the lens to him on Monday, but Covid may delay its arrival …

Fingers crossed he can do it, and that it will be for the $150 he estimated.
