This lens is big. Close to 5 " in diameter. Back in the days of the 90's there was one in every business for meetings to replace the chalk board. They were often built in to conference rooms as a podium. It projects a 4x3 , TV size image, from what I am gleaning... 200cm, but most had a problem with focus, at big size.
Big size.... Not for theatre ... Only for conference. Small room, medium room, even large room, but in dark controlled atmosphere. So too, out with the grocery market, in with the Walmart!
I could use a manual, too if anyone has one they would part with. I found a remote on eBay for about 20$.
