I started my humble collection not so long ago, so I payed a bit more than those 10's and 30's for few of them.
I would love to get my hands on a Trioplan, but they're so overpriced.
In another note.. I saw you joined the @qurator server, I am part of the moderation team over there, so welcome aboard!
I was going to invite you to join Photostreem but I see that you are already there as well. You know where all the cool kids hang around :))
RE: So why would you want to use that projector lens..?
