My longest lens right now is a 1000mm Meade C90. Use it for bird watching. Bird portraits at 100ft.
How big is that Elcan?
There are some strange optics out there. I have a lens from an Optical Computer that used (Pinky to lips) LASERS to perform the computations At Fantastic Speeds. They were made in the 1980s, and cost about 40,000 per lens. They are very pretty, and very heavy.
