Thanks Klaus.
You have a somewhat complete overview of all Projection Lenses? Or are there still a lot of 'discoveries'?
I have a few, but there are so many on the market which have been made by different lens makers.
Basically all optical companies have made them since decades if not centuries, dating back to Petzval
which still is a very common lens design for projection lenses. There are still discoveries to be made
and cheap ones to be found (especially russian ones), although the prices went up considerably since
the "hype" started and I also plead guilty for that trend... ;-)
