Hello guys,


is there some documentation available that puts all those lenses


- glass

- hybrid

- all plastic


in a list of advantages/disadvantages,resolution,optical properties , ...


I found an old USPL pdf from the early 90's explaining some aspects


but have never seen HD-114 and explained lenses pop


up on projectors nowadays


is it possible to use older lenses (mostly all glass) to


further improve PQ ?
