Came across someone selling this lens on craigslist, ive never heard of it and it sounded insane so of course i looked into it, i havent been able to find anything on this lens , wondering if anyone on here knows anything about it? from what i read its somewhat rare, , i found these pics tho, no idea whats even going on, some insight would be legit!
also what does it mean that there's no space in between the elements? and i cant find what kind of mount it is...
